TB42 to TD42 transplant

G'day, i inherited my Dads1993 TD42 turbo, it had boat lifter rack and the roof is full of rust and its eating into the two rear sliding windows at the top, considered my options and scored a grandpa spec 1992 TB42 for $2500 and had it flatopped to my partners place (she has two double garages and a big concrete area) for another $250.

ive read an excellent post on here by Andyh on his conversion, great post andy, heaps of info:049: The TD42 is a very reliable bus and runs very well, the TB42 spat a welsh plug and cooked the motor but everything works.

so plan is to strip out what isnt needed in the TB42 and get it ready for transplant, (selling the duel fuel system, reasonably new exhaust system, ECU, etc etc) both cars are autos and from what ive read my diesel will fit straight in, the diesel fuel tanks and plumbing will have top be taken out and transplanted as well, and the wiring loom and dash pod.

dads old gq shell will be for sale to.

so on with the planning:drunk:

Any and all advice welcome

I cant give you any advice on the conversion mate. But good luck. You have the donor car so theres no much else you would need to buy.

Thanks mudski, yep having the donor makes it cheaper, I can cut wiring loom sections out and graft them in, lots of posts on here exolaining how others have done it so should be ok 👍🍻

reading reading so many threads on how to do this, I'm writing down all the issues so I can hopefully avoid them

Hey mate did a conversion on mine years ago, don't regret it the best thing I've done to it. Very straightforward really, I didn't end up putting a loom in just the cluster and adapted the loom, also just put in an aftermarket glow plug timer which works well.

Also just put a new cab on mine which was same colour as the red & gold one out of interest sake . . .

Hi Rossco, I'm looking forward to driving the new bus, I'd love to know which part of the wiring you changed 👍

Hey mate you'll love the bus i recon.

There wasn't too much in the way of wiring had to change. Just extended alternator wiring across to the other side of the motor, starter, oil pressure, coolant temp all hook up again. Took ignition power from solenoid on carby to plug into injector pump fuel cut solenoid. Tacho I didn't do myself got patrolapart to do it but you need the td cluster and run a wire straight to the taco sensor in the motor. Not sure what pin you need to pick up think GQ Jett sussed that out with his. Originally had manual glow plugs but put in a Bogaart timer now which works great. Apart from the water sensor in the fuel filter everything works and looks factory.

Thanx Rossco, great info 👍👍👍

So Im set up to do the change over this week, just called an engineer in Geelong and he has suggested asking if anyone has had issues with vehicle exhaust emmisions? during a TB42 to TD42 change over? and who has had theirs done and where?

Can't see the problem with emissions mate unless you're not running a muffler , as long as you swap everything over the only difference is the body swap .
Interested to know if it's a factory auto or original .

from what ive been told, the td42 did not comeout with an auto ?

Yep from what I know there was no factory td42 auto in a Gq released in Australia, also no factory td42 with turbo. Only OS safari.

Incorrect. There was a small run of oz delivered GQ td42 autos. The family actually owns one.

You are correct in that the import safari and os gq did come with td42t auto.

Yeah right I didn't know that, must've been a small run.

So old mate shouldn't have issues with compliance doing the transplant into Auto then because of factory AU spec ok?

Mine is a 1994 and was one of the supposed 100 imported as a trial , I have seen close up another 94 that was original auto but had been converted to a manual and heard of one more also 94 that was drowned on a beach I think in WA and it was also a 94 .
The compliance plate tells you what motor , gearbox colour etc also tells you country it was shipped to originally for compliance .

Also buying a part from Nissan I have to say it's a 93 or 95 if I want diesel parts and tell them it's a manual , if I want gearbox parts same thing for years but tell them it's a petrol or computer says no .

Compliance plate from mine showing TD4.2 , auto box and second Nissan Aust .
Would be interesting if there were some from other years .

This is interesting. The one my folks own is a 01.1994 Model Complianced and Au delivered.

We are hijacking a thread here but do they have the TD stamp which I'm assuming turbo diesel .

The TD part of TD42 engine doesnt mean its a turbo diesel. The early GU 4.2 Were a TD42T same as the earlier safari import items. All oz delivered auto TD42 were NA.

another issue, height from roof to ground is 1850mm i susoect a 4 inch lift is in it

Got this from specs 1815 overall height .

plan today is strip the TB, remove exhaust, fuel tank, gas tank, fuel and gas lines, and engine maybe the rear diff and wheels as well, got 3 days in a row of 31C and working in a brick garage, beer oclock at 3 ;)

fuck old bolts :) exhaust is off without cuting any of it :) lpg tank is out, engine periphials, wiring, radiator efi shit etc etc, got codes off shockers, its got a tuff dog 2 inch lift front and rear, plan is today to change diffs and wheels over.

Attachment 73799Attachment 73800tanks out of the diesel, towbars off, back farked, beer oclock

its on again
