Gcg Turbo Upgrade!

[Anthony]

hey guys & girls,

im in the procrss of doing something with my turbo. Not sure if it put a T04Z and go the hole works or something else. I contacted GCG Turbs in sydney to get a ruf price on a T04Z. the guy told me they have an option that is you send them your turbo the refurb it, do the flapper mod with actuator and install a bigger turbine keeping all existing housings so it a bolt straight back on job. when I asked how does this compair to a T04z I got the answer it very close but not quite as big but very close my question is how much biger than std is a T04Z and has anyone had this mod done from GCG I want to find out if its worth it as it costs $2150. if its not really worth it I would rather put that money toward a t04z and setup. The reason for the upgrade is I have my std turbo running 18psi and I want to get my boost levels down to say 14 and maybe in the future push it a bit harder.

If anyone can help it would be great

regards

Anthony

I had this Turbo mod, it made 420rwkw's and 1280ish nm torque @ 20psi through a C4 3500 stall, awesome on the street, mine cost $1900ish from MTQ

While they say its a straight fit, too get it too fit properly(well what i consider properly) without the intake rubbing on the back of the power steering reservoir is a little more complex. Especialy if you want too run a Nizpro or similar Airbox

I wound up relocating the power steering tank, modifying the power steering, supply, return and pressure lines and modded the pump too suit the extended inlet hose.

Im very happy with the setup on my car. I can happily see 18psi @ 3k in 4th gear, and its taken alot of work too get the gate too flow enough and too get the Eboost im using setup right, otherwise instantaneous 24psi is on the cards.

I have this mod from GCG and Is definitely more than enough for a street car. Mine bolted straight back into place with zero modifications and is currently running a 4inch Plazmaman intake. However if I had my time again I would have saved my money and bought a T04 or something bigger just cuz I love the highmount look

Got any pics of your setup MrDose? I think Dalts was running a Plazaman intake as well and he said his was a fairly easy install

Hello Hiddeous,

It seems your turbo is modded more than what GCG do as you have a .70 comp housing. who done your turbo mod. im leaning toward the .70 comp housing way even though things need modding.
