GT 35/40 turbo fail?
I bought a GT 35/40 kit in December and I've probably driven the car for about 3-4 months at 7 PSI and a couple days ago it failed. I was ejecting oil into the intercooler and water out the back. Has anybody experienced this also.
I have a 94 FD with GT35/40 kit, Pettit large Intercooler, Power FC, other mods.

Re: GT 35/40 turbo fail?
could be 2 things:
1. lack of oil or the wrong oil dried up the CHRA
2. you sucked something in the inlet (dirt or etc) and broke the seal behind the wheel to the CHRA
BTW: what kind of intake do you have?

Type of intake
I have a Blitz intake on my turbo. What was kind of weird was that after a few weeks of having I noticed a slight amount of oil collecting in the bottom of the compressor side. So after 5000 miles it must have totally failed due to wrong fabrication. I also noticed that this turbo does not have any indication of being a Garrett turbo. All it has is the imprinted part on the Turbine side. For all I know its half a Garrett and the other half something else.

Returning the GT 35/40 turbo
I sent it back to the dealer and he's going to take care of the freight to Australia. He did say that it will take over a month.

Oil collecting
I noticed the Oil collecting also. It was mimimal when I first saw it. I noticed a few months later after installation that sometimes it happened, I really don't know at what point in time it would do it because I only ran it for 5000 miles at low psi. It was just bad luck.

all turbos will collect slight oil on the bottom of the compressor due to:
1 PCV recirculation
2. inadaquate blow off valve
3. turbos will sometime spray a lite mist of oil during boosting
if you look at the bottom of your IC you might see some oil there.. whereever oil can get trapped it will eventually collect there.
that is normal ive seen it with all my single turbo upgrades

Yup. Garrett BB centers use oil pressure to push the shaft and bearing together. You're not supposed to run more than 60psi through the ball bearing center or else you're looking at premature failure. This usually means you need a restrictor on the oil feed line since a FD hits 90+ psi at redline.
Trivia: The big difference between the Garrett (HKS) and IHI (Apex'i) ballbearing turbos is that the Apex'i units use a sprung clip to produce constant seating pressure on the bearing instead of oil pressure like the Garretts.

power put down
I don't really know how much power I was putting down because I still don't have a good enough fuel pump and bigger injectors to accomodate for the power. I didn't want to hurt anything so I kept the stock 7 psi spring.
I'll let you know once I get my turbo back.
