Td42 Turbo....to Many Kms??

[coilcabclifford]

Gday all,
I have a gq ute td42, thats got about 320000kms on it.
Ive procrastinated about putting a turbo on it for quite some time. Ive heard alot of different things about putting a turbo on this model (engine build date 6/98) and dont really know what to believe or what is the correct information:
- Apparently they have lighter pistons and oil injectors that are not as strong as previous models, some say it doesnt matter, some say its a problem.
- That while 9 - 11 psi boost is considered conservative anything to much above that can cause problems?
- I have looked after this ute very well as far as maitanance goes, but is 320kms to much to put a snail on it?
- Its on diesel / gas: could that be an issue as far as longevity goes with the turbo on it aswell? I havent heard of anyone with this set up with an aftermarket turbo to compare with.

Bottom line, I know like many of you out there, that they are a bloody good strong engine, but I just dont want it to go bang. :ranting:
Any feedback / info would be great.

Thanks

the 98 model might be a bit of a concern going by what every one else has said about year of manufacture
but if you have maintained it well and is still running good personally i would try for a conservative amount of boost say around 9 psi

personal opinion only and like you said they have been built with lighter pistons and also they dont have the oil squirters for piston cooling

yeah ok, and the thing is to, im going to try and keep the ute for as long as i can, run it into the ground. Not to say that people who have fitted aftermarket turbos dont achieve longevity. On track 4x4 have qouted $4500 and for what i want to do to the truck in the futrue that could probably nearly do it all with that sort of money.

Ha ha she has just run in.

Bang!

[coilcabclifford]

yeah......bang. Heard of it happening on quite a few even with lower kays

Ive never seen diesel / gas on any thing smaller than a truck how do they go with economy and power whats a conversion cost is it worth it ?

[coilcabclifford]

yeah its definatley worth it mate. Ive got an extra 25% more power and economy.
The gas is injected in via the inlet manifold and mixed in with the diesel. Its not straight but yeah mixes in with the diesel to make it burn more. With a 80lt diesel tank i have a 30lt gas tank and they both run out at the same time. I get 170km more with spending and extra 6 or 7 bux

I would get a compression test done and see how it is wearing. Mine had 350000 when I was looking to get a turbo but I was told by west end diesel that the compression was to low. It was even across the cylinders but they recommended having the engine rebuilt before fitting a turbo. It was still running really well and it still is now.

I would say that having the gas system would be a concern with fitting a turbo with that many km's unless your compression is still really good.

mates truckis a 97 coil cab n it has 360 on it. been turbod for years and still fine. id never run big boost in a late motor tho

[gqturbopatrol]

mate ive got an aftermarket turbo on a 92 gq. it done 450000 and the turbo has been on since 100000 and all ive done to the engine is injectors and fuel pump and it is still going strong. it is running 10 psi but then again they say the pre 95's are a tougher engine.

[ozy1]

id say go get your compression check, if it turns out okay, id say mild boost shouldnt casue you a drama, if tuned right, with the diesel/lpg it should run cooler inlet temp, thus healping to increase te life of your motor anyway, but talk with the experts first, always

[sudso]

My TD42's done 320 odd thou and it's still going strong with the turbo on it.
If the compressions good and the valves seal well etc go for it.
