Turbo & LPG on GU 99 TD42 N/A?

Hi All,

I have just bought a 99 GU DX 4.2 N/A wagon and am looking to fit an aftermarket turbo and gas. I have spoken to 2 'reputable' turbo shops in Perth and have been told that TD42 motors built after 1995 and before 2000 have weaker internals and donot cope well with excessive heat.

These shops advised me that if I were to turbo:

1. Not to boost above 9 psi

2. Pyro not required. One said when they dyno they tune to ensure egts do not exceed 475 as opposed to 550 on pre 95 TD42 motors.

3. Donot use lpg as this will increase egts and threaten longevity of motor. One of the shops does fit LPG and he was pretty clear that he would not do it on a 99 TD42 N/A with aftermarket turbo.

4. Go for watercooled garret turbo as this will be better at keeping heat down.

5. 3 inch dump pipe with 2.75 exhaust is all you need. 3 inch is 'pose value'

Now I have researched this issue to death on many forums and am starting to get confused as. Am I being fed a load of by these installers?

I am not after masive amounts of power as the truck is a daily driver/tourer towing a camper trailer.

In my view if I go for 9psi boost (water or oiled cooled turbo) and 3inch exhaust with an EGT then gas it but get the gas tuned mainly for economy with obvious power gains and watch EGTs I should be ok in the long term. What do you guys reckon?
