OK, waiting to pay the invoice from Leroy Diesel for the DS-2 set. $275 USD plus $40USD delivery

Ordered, now just waiting for its delivery, will go on at the same time as the timing gears and fluid damper

[PeeBee]

Finally got the part number for the high output water pump from BD. Its an AC Delco 251603. It appears to be the same capacity as the original high output pump, but has a screw on fan assy instead of a bolt on. Its serpentine belt driven also.

[PeeBee]

Ordered the fluid damper this morning. Ended up going with Leroy Diesels instead of Summit. Summit made a meal of the enquiry and their arrogance lost them the sale. Could not get a delivery cost out of them, their auto check-out system contradicted the sales guys and then I had to resubmit a product enquiry after sending them a request to delete the original - NOPE, why should I have to do the work to fix your screw-up. Pack of monkeys.

One email to Leroy Diesel, invoice received, paid 5 minutes later, 15 minutes later had tracking number, now thats service.

[PeeBee]

These were waiting for me when I got home for R&R today, timing gear set and fluid damper. Heading over to the land of Yarra Glen on Monday to pick up my safely stored Supercharger kit from Mr MB and AB - thanks guys. Its real when the bits are in your hands - now just have to find the time to sort it out.78230782317823078231

Guys, radiator was ordered with bungs for upper and lower temp sensors plus a redarc low coolant sensor. True to form, the Redarc bung was not added. Can you advise how far down from the top of the radiator it should sensibly sit - will have to get this welded in before I start.78263

Dare I make the reckless statement that I have finished buying stuff for the s/c conversion???? Just pulled the trigger on a billet aluminium harmonic balancer pulley in 8 rib config from Leroy diesels. $250USD plus freight of $75USD. This will replace the unit I had supplied by BD which is a heavy steel and rubber unit - prone to delamination over time, and will reduce weight by 3kg approx.

I thought the pulley set you got from Bullit had the 8 rib balancer pulley.
My understanding is the balancer is the bit with the rubber but not the actual pulley, is that not the case then?

Bullet only supplied the s/c nose pulley, all other pulleys via BD.

There are two parts with rubber,the factory balancer and the factory pulley. I have replaced the balancer with the fluid damper and now replaced the 8 rib pulley with the aluminium billet pulley. yes, its confusing, and surprising, but until you actually get the parts into your hands, you never know what you are getting. I cannot check whats on the vehicle without pulling it apart, so am going with the two parts upgraded without the rubber.

Where are you up to with your build? Going OK? I sent you a PM - did you see it?

[poindexter]

The shop manual that I have shows no rubber on the crank pulley

Just saw the PM.
OK, time for an update :

Got assurances that my "project" will get the attention that it deserves after easter. If it does not, I'll be looking else where.
At the moment I have not been pushing too hard as I've just been through two major renovations at the house, but that has all finished now.

Interesting, I am now wondering if BD have taken the harmonic balancer pulley and machined the outside off to produce the 8 rib pulley - as it looks suspiciously like that pulley come to think of it. Anyway, I have the replacement on the way so don't have to think about it.

Hi Guys

I've been reading through the thread for a few days now trying to soak up as much info as I can. I'm looking at buying an all ready converted GU with the turboed 6.5 + 4L85E. Apart from overheating issues, is there anything in particular that I need to be looking for with these engines? Apparently the one that I am looking at has recently had the injectors replaced. Is that something of a concern?

Cheers

If it is already converted and the owner has had it for a while, I would think the majority of niggly issues associated with the conversion would be sorted by now. I have a GQ manual so cant comment on the auto. Injectors could simply be age, or crappy fuel or tune related perhaps - is this a private sale or thru brunswick? Can you get a service history verified?

Do you know if the motor was new or a s/h or BD reco engine? If a s/h engine could just be old injectors needing to be replaced.

[thebrod]

Thanks PeeBee

It's a private sale, and I haven't actually been to see the car in person yet (hopefully next weekend). If it were through BD or a dealer I guess I'd feel a little less nervous as there would be some form of warranty. I wonder if I called BD with the VIN or engine number if they would have the details of what was done at the time of the conversion?

[poindexter]

Update time.

It has started,

Engine out, engine bay being prepped, firewall is having shiny heat shield/sound deadened material fitted.
Hydroboost brake booster is going in.
Looking forward for trial fitment of engine and gearbox as I want to see the oilpan to diff clearance.
The 6.5 blocks lack a trans mounting bolt at the 12 o'clock position, I'll be putting one on with a "beaming bracket" that will bolt on and pick up the mounting hole on the trans.
I'll post pics when I checkout progress this week.

Hi all, currently puting together a turbo kit for my gu 6.5 and looking for a decent large top mount intercooler. BD ones are too small imo and the cross country set ups are $2500. Any recomendations?
Cheers

Jump onto the Aussie P400 Optimiser facebook page - quite a few guys on there that have done the yards you will benefit from.

[poindexter]

Update time:

Engine is together after the gear drive and fluid damper update.
Trans is trial fitted to engine and "beaming bracket" design has commenced.
Existing engine mounts removed from chassis, and new brackets are next to go on.
I'm keen to see the engine in "the hole" to assess the exhaust and fan to radiator clearances.

78934

[poindexter]

Alright, time for an update:

The engine has been trial fitted into the engine bay and positioned as per the Marks adaptors bits.
I'm not happy with the location, so, the position will be revised approx 35 to 50mm rearwards to allow additional clearance to the radiator.
From my understanding, this is a common problem.
There appears to be plenty of room to move at the rear of the engine, with the drivers side cylinder head to dash panel being 70ish mm gap at the moment.
Interestingly the upper pulley seems rather high.....
I'll be looking into the oilpan to front diff clearance to see if I can lower the motor.

that is all.

Yes I'm very much keeping an eye on the oilpan to diff clearance, no suspension limiting for me! I'll modify the oilpan if needed.

Engine location 2.0:

[poindexter]

Update time.

Engine location 2.0 is now final.
Oilpan to axle housing clearance is good, engine to dash panel is good, and engine fan to radiator is good.
Supercharcharger to hood panel is tight, touches on insulator, however, the insulator in that region is quite thick, so trimming is an option.

79222

Next on the list is to get the exhaust headers sorted.
This may well be the biggest challenge, as on the drivers side is bugger all room, need to get creative for this.

that is all.

[poindexter]

Update,

Pic to show the oilpan clearance. I'm happy with the way the oilpan clears, no issues when the springs are taken out and the chassis is on the bump stops.
Pic to show the exhaust, will be running the supplied manifolds until its on the road, will assess and see if custom one are needed.
The clearance is tight, and the supplied manifolds not too "sporty", however I'll see how the P400 performs.

Good to see the progress. What clearance do you have sitting on the bumpstops for the sump? Did you nick a corner out of the sump to get the clearance? If its close I would consider solid blocks to be honest as its better to hit these than put a dent in the sump I would think. You certainly have more clearance around your motor than I do. I am not sure hydraulic units would help unless they are set up to bottom out - I still have these for consideration on mine, however my coils are just about right I reckon - Dobinson 110kg constant rate units from memory on the front - guys in the dandenong shop set them up for me - very helpful.

Hi PB, the bumpstop clearance is 25mm, the oilpan was modified by BD and it seems to fit, which is a miracle considering what Greg has supplied.
The hydo's would be an option as you can control the "hit rate", but I'll see how it handles the bumps when the truck gets mobile.

Thinking about the rocker cover vent, which is only on the drivers side bank of the engine. Why isn't there a similar vent on the passenger side? Is there any advantage of venting this rocker cover? I read an article last night where there was a noticeable build up of gunk in the non vented side cover. If I went ahead and vented the passenger side as well, would it create any problems? I have a catch can for the drivers side. Also, wonder if I could simply buy a drivers side rocker cover and install it on the passenger side?

My understanding is that it's technically a "PCV" valve or vent. That being positive crankcase ventilation or something similar to that. It's purpose is to vent the blowby and other gases generated from the crankcase, not specifically the rocker cover.. so I couldn't see any real benifits to fitting another vent on the other side. I also don't see any detriment if you really wanted to.

[0-TJ-0]

So what happens on the non vented side?

Well it's all interconnected. The oil is pumped up to the rockers and gravity feeds it's way back down to the crank case. If one rocker cover is vented the whole system is. The "non-vented" side just wouldn't see flow so to speak. As long as you're keeping good oil up to it there's no reason either side should gunk up.

Just purely speculating now but out of the 2 I would have expected the vented side to accumulate more gunk as it sees a constant flow of fumes and blow-by.

[0-TJ-0]

Perhaps the fumes act as a bit of a scrubbing/cleaning agent as they're probably fuel rich

Trying to remember my old FJ modded 350 V8 petrol days, think one side had the oil filler vented cap and other had the vacuum back to Quadrajet carburettors?
Our 6.5 diesels as you know Phil mate have the oil filler smack in the front middle so couldn’t also like O-TJ-O mate kindly mentions foresee a problem either with venting both sides?

OK, thanks. I don't think I will do anything right now it it involves removing the supercharger, and injector lines to get the rocker cover off. I spoke with the diesel mechanic in the workshop at the mine and he said its a 'nice to have' but not entirely necessry as there are vent passages around the pushrods for one that would allow pressure venting

[poindexter]

OK guys,

I would like to see some pictures of your accelerator cable setups, at the IP end.
I'm at the stage of running the cable and would like to see some solutions, or is there only the one obvious design.
Bullet wanted some stupid money for a "bracket", how hard can it be?
Thinking that the cable run will come from the front, connect to a lever on the IP? and that should be that, or am I wrong?

Also, for you P400 guys, what water temps are you running, and is keeping the airflow to the radiator as critical as the regular 6.5 motors do?
I have in addition to the AC condenser, power steering and radiator, the engine oil cooler, trans oil cooler and intercooler heat exchanger to mount.
Mounting all this in font of the would be a challenge at the best of times, without the cooling issues of the 6.5 in general.
Looking at putting the "extra stuff" under the tray.

What do you guys think?

I bought the stupid bracket and linkage and binned it. You needed to be a 1cm tall 8 jointed insect to install and adjust it, totally impractical, and yes, expensive. I went with the BD accelerator cable from the n/a installation. BD claimed I needed to change this to a GQ TD42 throttle cable assy, which I did, then found it would not fit, so changed it all back again. The BD cable can bee seen in the shot going over the s/c snout. The other cable is the cruise control, which has not worked since I mangled it in the fan blades. The BD cable cost be around $150 as I wanted a spare. Its a fair piece of gear.

[PeeBee]

You are welcome, glad the install is going well.

[poindexter]

Update time.

Small hiccup with the torque converter, the nose locator was too long to fit into the crank.
The guys who made up the converter popped out, picked it up and and altered and returned for a perfect fit.
Part and parcel of pioneering a combination that was never offered by the factory.
The engine location was changed, as I didn't like the offset, now all central, millimetre perfect.
Radiator fan shroud fits as intended, exhaust done to the rear axle, hydro-boost going in next.
I'm looking at putting both batteries under the tray to remove weight from the front of vehicle.

I think I might end up goin to one of the local mechanics here Tuesday as he has one to have a look at, to see if there is something I am missing.

There is only 1 spring. Have you adjusted the threaded sleeve with the lock nuts - 1 either side of the anchor bracket for the throttle cable? Where are you located?

OK time to post.

finally got the truck home after 36 months.
I'm happy with the truck, but not the time frame, although it doesn't drive well due to the 6L90 being in limp mode, and the accelerator pedal needing too much pressure to use.
The truck is going to have the air bag replaced thanks to TAKATA, and then it's time to get a cal into the trans.
Wiring is not to my liking, however it starts and runs, I'll have something to do over the next few weeks.
I'm also going to do the center console for the new shifter, and looking at what needs to be monitored gaugewise.

Well, got the airbag replaced, so the rego doesn't get cancelled.:animierte-smilies-t

The trans is in limp mode, due to the engine rpm and the throttle position sensors not being connected, so its reverse or third gear.....
But it does sound good,
I did notice the the p/s pump whines a bit, but I guess that's probably normal, might have a look at the hydroboost push rod adjustment as I think the rears are dragging a bit.
Need to sus out an auto elec locally, so if anybody knows someone who's switched on, let me know.
Then it's on to the center console!

Funny enough I have an endless air compressor for sale and a converted sanden compressor for sale - PM for details. Both running vee belts, neither even done an rpm. The genuine is missing one mount ear though. I could not get mine to fit when running the vee belt but then I was running the a/c as well

Time for a little write up on putting the 6L90 trans behind the 6.5.

The 6L80 & 6L90 are almost identical in physical shape and size, the 6L90 is about 17mm ish longer,
Both will bolt right up to the 6.5.
On the 6L90 and some 6L80 trans, you will only pick up 5 of the 6 mounting bolts, the "2 o'clock" bolt on the drivers side is missing on the trans.
The early 6L80 will have that missing bolt hole available, and that convertor housing, which is integral with the oil pump housing will interchange with the 6L90.
There is no provision on the 6.5 to pick up the "12 o'clock" bolt holes, and there are 2 bolt holes available on the bottom of the trans convertor housing, but no provision on the 6.5 to pick these up.
I have had bosses welded to the aluminium oil pan, with brackets to pick these up, to aide "beaming strength".
The convertor is where it starts to get interesting.
In the US, there is a version of the 6L90 that is used behind the 6.6 duramax diesel. that convertor is what makes this trans doable behind the 6.5.
I got a trans specialist to modify my convertor to match the 6.5 flex plate, and the 6.6 internals to make this viable, as the 6.6 max rpm is 3400, not the 6600 of the donor vehicle trans (HSV GTS)
An 3400 rpm will suit the 6.5.
Marks 4WD makes the adaptor to the Nissan transfer case, just don't use a 4x4 trans as the splines won't match.

Now, it's HSV GTS shifter on the trans tunnel with either a cable or rod connection, and you're all done....

One small problem, trans control, most will say a stand alone controller is not available, but there is.
Zero Gravity sell one and it comes with a harness, requires just a TPS and engine rpm to make the trans work.
Also, that US vehicle that has the 6.6 and 6L90 combo, will also supply the initial calibration that gets loaded into the trans.

My trans is at the moment in "limp mode" as I haven't got those 2 sensors connected. It still drives, but only in 4th, no TC lockup and I get reverse.
I chose to drive in "limp mode" in order to get the airbag replaced before the end of the year and avoid the rego getting cancelled.

So I'm getting close, keen to see how the trans handles the 6.5, as the is no provision for a torque cut on upshift.....

[PeeBee]

I may have found the 'ticking ' noise I mentioned. On start up this annoying ticking sounds is quite noticeable. i thought it was the same noise some have reported with the fluid damper installation, however that didn't sound at all right as the damper can't move. Anyway, dropped the belt off and checked each pully and found the auto tensioner wobbling a bit and the clamping bolt finger tight - odd because this was loctite'd when I did the swap over. Anyway, the issue is the clearance between the brg bore and the mount peg on the adjuster - there would be a good 0.5 mm gap, its as sloppy as, so relies only on the clamp bolt to hold it and i am sure the tension of the bolt pushed it to one side. Anyway, i have bogged up the clearance with a liquid metal product and once its set will reinstate it. I have spoken to BD, 'never heard of this before ......., anyway, waiting for their solution ie a correctly fitting brg to stub and that should fix things. i drove the vehicle back into the garage and no noise, so hope this is the culprit. There was a slight amount of axial movement on the PS pump so this would be the next focus if the tensioner hypothesis is incorrect.

Update - BD checked all their stock and they are the same, sloppy joe fit, thousands of them out there so I have asked for a precision one to eliminate this, and the PS pump axial movement is normal, and the same happens on the vac pump, so maybe I have not found the noise source?

I may have found the 'ticking ' noise I mentioned. On start up this annoying ticking sounds is quite noticeable.

Well, the noise is a lot less pronounced and does not last for anywhere near as long now that the bearing to shaft void has been taken up with liquid metal. Certainly nothing like it was, so think I am on the right track, or its now just a sticky stiff 8 track belt - trying not to get over anxious about this right now.
Took it out for a burl, new tyres, wants to float around a bit, so looking at pressures, but they dont look visually out of sorts - might just be a different pattern thing. Speedo is out by 10klm/hr, so probably should change the gearbox speedo gear - there was a chart I saw 'somewhere', can anyone post it up, shows the gear tooth number. I am going from original 32" to 33".
Tried out the water spray system today - total dud. not enough water/mist too fine, so back to looking at nozzle and spray combo's when I get a chance.
Had to modify the belly tank fill pipe as the offset on the rims leave a lot less clearance inside the guards - wasn't that difficult, just squashed the tube to generate some additional room and put it back together.
Need to get the a/c system pressure re-checked as the Interchiller is not as effective now it seems, but then again, it could be my jinking around with the external heat exchanger add on that's nobbling it - will get to the bottom of it soon enough - the heat exchanger is the only thing that has changed and the performance has gone to OK to not quite OK.

OK, ticking noise resolved. The Gates greenline or fleetline belts have a tacky back surface. This tackiness is releasing on the back side running pulleys it seems with a 'pop'. I took the vehicle down to the mechanic I use and he listened then went into the workshop to return with a graphite puffer. He applied the graphite to the back side of the belt and at the idler pulleys and the noise stopped instantly. Happy happy days. Still waiting for advice on the precision pulley from Brunswick - might have to say i will buy another motor to get them interested in responding i think.

Update - BD came back with a cost of $150 for the revised pulley which involves machining and putting a sleeve on the existing tensioner arm, then fitting a different ball bearing unit to the pulley with an increase bore size, so ordered that. Just kicked the truck up again now that everything has cooled down and the clicking is definitely gone. One thing to note is that the various belt noise sprays on the market don't work well with multi vee configured belts, more round and Vee belts.

[PeeBee]

Well guys, good news, most unexpected, but Brunswick have decided to supply and send the new pulley assy for free - yep, no charge on the basis I guess that this configuration should never have been adopted to begin with. Absolutely floored me.

ripped the interior out chasing that knocking noise since I put the 6.5 in......
sort of sounds like rolling thunder, oh well, might as well put some sound deadener in then I suppose, will keep me busy for a while me thinks....

Merry Christmas Ralph Mate!

Ok, the drivers has been done, just need to fit carpets.
Stage one deadener, heat shielding, stage two underlay, now off to the passenger side.

All right, passenger side done.
At SWIMBO's request, I will get new carpets. So none installed in the pics.
That just leaves the doors to do which will be an easy job.
One thing for sure, if you are near your GVM, the Mass Noise Liner ( the black stuff) will put you over.....
Put the thermal barrier along the whole passenger side as the exhaust runs under there.
Glad to get it done before works starts Monday.
Seats are back in and time to start her up.
Does work though, you can certainly hear that big boy under the hood, but just a little quieter now, will make touring that much nicer.

Question guys:

how long is your throttle return spring?
I'm having issues trying to get a reasonable feel on the pedal, it is currently way too strong, and I suspect that the geometry is all wrong.
this is the setup I have,
If I know what the original length is, it gives me a starting point...

Post #57 of my build shows the spring fitted and the same mount bracket - photo is off MB motor. Brunswick can supply you with the spring and the bracket for sure. I sourced these from them - as usual they sent two variants, a single and a double coil version. Both are dimensionally the same, spring rate just doubles. OD of coil is 15mm, wire dia 1mm 14 active coils on the single. double has 14 active coils also, wire dia 0.75mm, inside of coil ends is 60mm approx overall. I run the double coil version, but carry both as spares.84427

Thanks again Pee Bee for the info.
I'm assuming that you are running that bracket and spring with the supercharger then?

[PeeBee]

Here is a pic showing the bracket and the pump with the spring set-up, taken when the heads were off recently.84428
Accelerator cable to the connection with the gold coloured clip, and bracket configured for accelerator cable and cruise control cable, since deleted. Just noticed my spring in use is the single wire version

[PeeBee]

If you want the installed dimensions of the spring, let me know and I will put a ruler over it

[poindexter]

that would actually be great

[PeeBee]

No worries, you are welcome.

Hi guys,
I have joined the 6.5 Chevy team.
Brunswick Diesel install and I have had it back only a couple of weeks.
Still working towards the 2500k for the check in service.
Not that much thirstier than my 2002 3.0 Di.

Very nice installation, I hope you don't end up with a pile of bee-stings like I did!

[poindexter]

time for an update, albeit a small one.

finally got the accelerator spring sorted.
I have been told that the Bullet linkage is rubbish (looking at you Pee Bee). but it has in fact turned out to be perfect.
The supplied accelerator spring and bracket is less than ideal, so I got my hands onto a "standard bracket and spring" (thanks Dewars), and blow me down, this has turned out to be perfect as well.
Now that is done, I will do a more optimised bracket to satisfy my inner engineer.....

Now to things 6L90 related:

It has taken Zero Gravity (suppliers of the Gateway Module and software) basically 10 months to realise that the software and calibration supplied was for the wrong transmission (4L80)
Now that little faux par is behind them, guess what? the gateway now talks to the 6L90, and even better yet, reads the CAN and engine sensors!!!!
So now the trans has been flashed with the correct CAL, and talking to the gateway, I can finally make some progress on the programming.
All the mechanical side of things has been perfect, even the starter motor issues have resolved themselves.
While this has taken a while, with COVID and other dramas, I have been learning how this shit works, mind you, I didn't want to at the start.
I've got the Trans calibrator at work onside to do the programming ( he was lead calibrator on the 6Lxx program in the States), so at least I have access to someone who knows what they are doing....
Next post will be huge, you'll see.....


that is all

[PeeBee]

Well so glad you are now living in a perfect world. And yes the Bullet linkage will remain crap in my eyes moving forward, but glad your perfect solution has transpired. So funny how you have two completely perfect items and still see the need to make them better - what next AI?

[poindexter]

Got this done just in time for the new year.
The hood sound insulation from Carbuilders
Went surprisingly well all things considered.

Hi guys,

Time for an update.

I have finalised the TPS and throttle return spring bracket, including the connection to the injector pump shaft (thanks Pee Bee).
Got it right on the third attempt.

87858

Did have an issue with the hydroboost at the same time, the knuckleheads that installed it, plumbed it incorrectly.
When the engine was running, the brakes were always on, but turn the engine off, the brakes were off.
Marks 4WD were very helpful in advising me what to do, good customer support right there.

The area of focus lately has been the operation of the trans itself.
Good news, is that after the dramas of the TPS and the gateway module, all is working as it should.
Currently creating the shift schedule and road testing to see how it goes.
The trans is shifting well, now just refining the shift points, no flaring on the shifts at all, and down changing well.
Once the shift schedule is to my liking, I'll work on the tap up tap down of the shifter.
All in all, I'm happy now that I'm in this phase of the trans swap.
There was a time when I thought the trans would flare the changes, but this has not been the case.

Now that things have started to get sorted I'll post more often.

[PeeBee]

Good job , glad to hear some progress. When is it going to be on the road as such?

[poindexter]

I have got an electrical guy on the hook to tidy up the wiring, and by that time the trans should be done and dusted.
So a few more weeks me thinks.
87859

[poindexter]

an update to the transmission side of things.
The calibration seems to be working well, I'd say it's at 80%
6th gear hooks up now, and I just need to get it to hang on a bit better,
All in all, very driveable, will get the tech crew to fine tune the cal at work, will work on the 4wd mode next, then it's TUTD time!

[poindexter]

another update, truck has been delivered to have the wiring sorted, woohoo!
87903

[poindexter]

It's been a while, so here is what has been happening.
As part of the electrical wiring clean up, the instrument cluster will be refreshed
I'll be replacing the instrument cluster with an AiM cluster, so that I will be able to monitor multiple sensors without having the dash full of gauges.
The dash will also display transmission gear and drive mode position.
3D racing solutions did the dash insert after I had sent them a sample cluster to model, they did not do Patrol GUs up until this point.
The guy doing the wiring is an ex motorsport electrician, and is very familiar with AiM products.
Looking forward to getting the truck back.
More to come....

Gday Poindexter. My guess is there was a late Saturday night misinterpretation of your pic showing 234kmh and the fact it was just a demo pic, not a dash reading.
