Turbo on a GQ

Brian,
I had a 93 GQ and had a Safari Turbo installed. It was a Garrett turbo, but not sure what the model/size was etc. It was a straight bolt on job as far as I know. They had to move the air filter from lengthwise over the inlet mainifold, to crossways, over the back of the tappet cover. They supplied a cross-over pipe from the turbo to the inlet manifold (which you are going to need in addition to the turbo itself).

My advice would be to seek a professional fitter to put it on. They are high tech units and need to be set-up properly to be of any benefit. The fuel pump settings need to be altered and it would be preferrable to have the injectors tweaked as well.

Speaking of air filters, I have often wondered why the GQ needed 2 filters? The GU I now own only has one air filter, about the same size as the pre-filter was on the old GQ. I reckon if I was converting a GQ today, I would probably opt to do away with the main air filter assembly altogether as it is a bloody nuisance.

As far as boost is concerned, the standard turbo fitted to the GU runs at maximum boost of about 9psi. I had mine checked over and modified slightly by that diesel place in the NSW southern highlands. They made a minor modification to the small rubber hose on the turbo and it now shows maximum boost of almost 12psi. I have only become aware of this when I recently fitted a boost gauge. I was curious about what would happen if that rubber hose alteration was disabled, so I pulled it off the air filter housing and whacked a bolt in it temporarily and the max boost was then down to 9psi.

Turbos are great, but you need to get it done right the first time.

Theres more to it than just the snail..

Crossover pipes, manifold, etc.. Then you have to get these to match the snail you got cheap...

If your on the cheap, call soem of the bigger turbo places, they are doing $1000-1500 for Ex- GENUINE GU Turbo systems, that people are replacing with the good kit aftermarket gear.. Dude in Qld on OLimits seems to get hold of a lot of these for "mates"

And your well and truly better off to have someone who knows their crap set it up or it can cost you 100's by so called experts. Installation you can do yourself, theres not really anything to it IF you get a kit, like the Denco DTS, AXT, or Safari but safari wont sell to you to install yourself.

I believe you guys have just given me some great advice...... which is exactly why I posted on this forum!

After reading the responses SWMBO and I have decided to wait and have a brand new system installed.

Thanks guys!
