How many kms are to many?

[Fity]

I am looking at buying a 2.8 or 3.0 l GU and do a TD42 conversion either straight away if I pick up a GU with a dead motor our eventually when a good TD 42 turns up.

How many kms would you expect a 2.8 or 3.0 be good for? Assuming that the necessary precautions are taken to prolong their lives? There are plenty around the 300k mark. I may have to drive it around for a while.

if you're going to do the transplant buy a 3 ltr you can use the gearbox and diffs. the 2.8 gearbox is too small check out marks adaptors for more info. As to engine life I can't help you sorry I have 178000 on the clock just replaced the turbo and nads and runs well 121.4 hp at the wheels with chip and mods

Thanks macca.

I thought I read somewhere that there was a plate on the 3.0l bellhousing which you take off and the 4.2l bolts on after fitting a 4.2l gearbox crossmember to move the gearbox forward and let the motor clear the firewall?

Is the gearbox up to the extra grunt?

As far as km's go...
I've driven a GU with 700,000km's, it surprisingly drove very well! It had a couple of issues like the drivers door hinge had dropped a bit but I was very impressed.
Obviously it depends on the sort of driving but these cars are very truck-like so will go a long way!

That sound about right and yes it's up for the grunt the 4.2 is only a little bit more power. Thay still use the gear box for Ls1 and chev 6.5 ltr conversions

Great info.

That will save me looking for a replacement gearbox for the conversion.

I have a tb42. ..Petrol just about to clock ova 600,000kms and still going strong and has pulled a heavy trailer all its life and has copped a punishment from me on and off rd. .... I think a diesl should last longer than a petrol

I assume you have a manual as the auto's don't swap over just the manuals forgot to add that.

Yes it will be a manual.
