Conversion was done in 2005 by Brunswick.

In saying that what needs to focused on with our diesels is torque. You can't have hp or torque without each other anyway. We want to aim for fast torque rise and then a nice flat torque curve.

Something which is difficult to achieve with an asthmatic engine?

Yes but how many miles on the engine itself? Was it a re manufactured item or a "low mileage" option?

Yes the torque rise is ok but you can certainly notice how short lived it is.

I have no idea mate I will have to get hold of the previous owner.

Does it start easy when hot?

G'day, I don't go on here very often, & even less when I'm at work (FIFO).
no problem starting when hot, I rang Brunswick & the engine was a rebuild, sold to the last owner & converted by himself.
I think she has a done a fair mileage since then towing a van around the north of WA possibly a few other areas as well.
I haven't got hold of the original owner yet, but at a guess I would say 250K plus.

Today I ripped the aux battery out from under the truck and fitted it up in the rear, in front of one of the drawers. I was sick of seeing high temps on the battery monitor due to its proximity to the exhaust. 49 degrees C on much of my last trip convinced me it was killing the battery and I wanted to move it. I am posting this here as it really is a specific thing to the Brunswick conversions as there is no room in the engine bay.

Couple of pics.

New battery location. I just used the same battery box as it was easier to mount than a tray.


Shortening one of the drawers...





Just used rivets to refasten the back of the drawer.





Battery now sits right behind the Redarc BMS.



Now have some re-wiring to do to complete the job. Some new lighting, compressor power, and a fuse block are being planned.

Bit of feedback on how the 4L85E gearbox after doing the Meetup trip.

Around town - 10/10 - awesome mod. Sure beats the pedal work involved with the manual box.
Uses more fuel but thats 'cause you can't keep your foot off the loud pedal or the smile off your face

Cruising - 9/10 - just lopes along with the TC engaged and the 4th ratio locked up is taller again than manual 5th.
This means 1800 RPM is just over 100 KPH with 35's (that will vary with tyre manuf as all manuf are different dias and none are true 35)
Deducted a point because it usually drops straight to 3rd when the TC unlocks which is a slight annoyance.

Towing - 9/10 - same comments as cruising really. 35's are too big for "ideal" towing with the 3.9 diffs but that is tyre selection not the tranny.
Next trip I will throw my 33's back on to see how they go and I reckon they will be heaps better.

4x4 - 7/10 - Off road is a two step process. Point it, plant it. I need to get a manual TC lock up switch sorted and then it will be 9/10.

Fuel consumption - Not quite as good as I hoped. I averaged 20 LPH for the trip towing my van (2 tonnes) for over 1/2 of it but in fairness a few more tweaks of the programming and 33's would def improve that figure. By how much I don't know

I found it relatively easy to program the Tranny Computer (well at least the one that was supplied as apparently there are a few oprtions) but as I still haven't got my head quite around how the tranny works I took baby steps and still don't have it quite how I want it.

Good feedback. I plan to install mine when I get back home from work in August. Got a Compu Shift II and the manual TC switch. I ended up opting for the Wholsesale Automatics re-built Nissan tranny with their HD parts in it as I think I have more chance of doing this change out myself. Don't need to shorten the tailshaft or move the transmission support crossmember as you do with the 4L8xE etc.
