Another turbo thread

[Dads GQ]

Hello people.

Yes I know this has been touched on 1,238,002 times but who doesn't like talking about turbos.

So my GQ has some high mileage. Like 500,000 kms high.

tb42e engine... I want to turbo it but not too confident in the motor coping. So I am considering a rebuild before turbo charging.

Does this seem sensible or unnecessary?

Also it has extractors, will they get removed to install turbo?

As it is vehicle with alot of sentimental value I would like to keep it as close to how I got it and would actually consider not turboing it if it required removing something that my Dad put on...


I guess if that was the case I would still consider a rebuild and upgrade cams, whatever power upgrades you can go without turbo..

What are my options?

Thanks

Gday mate I have one the same...NA but i only got 250k on mine...

best bet...get your head and compression checked...make sure it doesnt burn oil and yes you will be swapping your extracors out for a turbo manifold and dump pipe that will have to be grafted onto an exhaust if your keeping it.

Thats as far as I have gotten...best to get the donk checked out by a pro before boosting...Boyles law come into effect when you add pressure to a cylinder...P1T1V1...basically your boom chamber will get hotter...your intake will get hotter and your zorst will get hotter so sort your cooling out as well. A good head and Radiator with new tweeked water pump should give you good results.

I am no expert and asking one would be the go. Actually ask heaps of em the same questions. Hopefully you gt the same answers.

best of luck...

In terms of cooling is there aftermarket options?

do a compression test mate, if the numbers come up good and it doesnt use any oil id have no issue bolting a turbo on, i put one on my old tb42e gq at 390,xxx kms and sold it 3 years later at 460k with no engine issues. that was running 10psi without intercooler. still wish i hadnt sold that rig was alot of fun to drive

Use a garrett 3576 or 3582 or non garrett equivalent.
You could buy secondhand of an xr6 turbo, but you take a risk doing that

The biggest risk for a conversion is the shit quality workmanship from the conversion mobs.
Some stuff is pretty rough

i had a much smaller turbo came in a kit from axt turbos, i set mine up to make boost more or less from idle yer it sacrificed a little power up top but had tons of torque down low more like a diesel and was very useable while still being quick enough to leave my dc cruiser for dead

I would be chasing that power down low. Bit of giddy up straight of the mark.
