the reluctor is for the DS-4
Sure, understand that, but what does it do? Did you buy the DS2? I have sent a note to the supplier to comfirm the DS2 is for the Optimiser.Quote:

Took a lot of trial and error but got it so I was happy in the end.
Main issue I had was setting the maps so that the Gear change points and TC Lock and Unlock points were suitable.
Top gear was easy but the intermediate gears got a tad messy 'cause the engine is such a low and slow revver
OK, waiting to pay the invoice from Leroy Diesel for the DS-2 set. $275 USD plus $40USD delivery
@MB, you might want to take a look at this pump setup from Summit Racing. It uses a machined impeller with a closer fit inside the housing to achieved higher flow rates - I think you can also buy the impeller by itself and fit it to the water pump. I am pretty sure the vee belt runs cw?

@poindexter, Ralph, where did you buy the fluid damper from? I have trawled back thru the posts but could not find it - thinking since I have to pull the balancer off to install the timing gears I may as well upgrade at the same time when everything is apart.
thanks

That suits clockwise rotation only, what do the 6.5 rotate?Quote:

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.
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.Attachment 78230Attachment 78231Attachment 78230Attachment 78231
Most welcome mate and welcome back home!
It is most definitely safely stored, on top of my now 6.5SC [emoji106][emoji106]

Thats fine, you will probably get more use out of it in the next couple of years than I willQuote:

The photo of the front of the engine is from the trial fit due to wider pulleys being installed
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.Attachment 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.
Nope, don't say it.Quote:

You're killin' me!! I dont know how I am going to fit half this stuff on - starting to look like its turning into a saga like the big guy in Geelong with his never ending timeline - now completed which is good for him.Quote:

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.Quote:

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?
The shop manual that I have shows no rubber on the crank pulley
Just saw the PM.
OK, time for an update :
It has been 5 months now and other than the engine removal, nothing has happened.
I'm at a loss as to what carrot to dangle under the noses of these guys, but money is not one of them.
To be fair, he has struggled with workload, but as I have said many times, that's not my problem.
He has a lot of work and is getting stuff done, just not my stuff.
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.
So, I'll give you guys an update 4th May, and please feel free to pester me.
that is allll
Just saw this entry in the shop manual:
Procedures for Destruction of Equipment to Prevent Enemy Use . . . . . . . . . . . . . . . . . . . TM 750-244-6
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.Quote:

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?Quote:

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?
I think you would find them very approachable, ask for Greg. He is the owner and super salesman, but he wont shut you down.Quote:

I'll be convinced when I see progress, or I'll be looking elsewhere...
that is all.
Bloody hell, you must be working thru the list of non performers! I will certainly want to know who isn't to be contacted as I may end up farming mine out as I am struggling with time to do it myself, however really would prefer to do it. PM me if you canQuote:

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.
that is all
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.
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.

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.
see pics

Beautiful Stuff Ralph mate!
Huge work both your good self and PeeBee are putting in, Legendary Blokes!
Please do massively consider as you’re already above onto front diff clearance to P400 sumps mate.
Higher power, hotter oil, originally were designed about 3.0L too less IMHO nuffy opinion mate!

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.Quote:
