I'm in a middle of a supra project for one of my customers. The car is complete but we can't seem to get it running right and have spent several weeks trouble shooting some of the issues.
Basically the car has a real lean condition at idle and driving.
car is done up from the bottom up, inside/out, front/back. Besides the subframe bushings, I don't think there's anything left we havn't touched on this car.
We started troubleshooting the lean condition with electronics at first and turns out all sensors, AFMs, 02, TPS, CPS, ISC, Ignitor, FP Relay, coilpacks, plugs, wires, Fuses, fuel pump, FPR,, injectors, fuelrail, pulsation damper, are not the cause of the Lean condition..
We then start checking the system for boost leaks.
1:- The Cartech Intercooler purchased new from suprasport... All 3 necks were leaking around the bends... Paid radiator shop to get it fixed..
2:- The I/C pipe kit that came from suprasport, was meant to mount to the stock intercooler and not the cartech so we had to hack the ends of the I/c for the pipe kit to fit.. Hacking the pipe kit caused the smooth surface on the ends to go away where original couplers were suppose to mate, and now we were left with a rough surface and the new couplers which suprasport also provided didn't seem to fit right and now caused the leak around the ends. We got around to fixing this, started the car and again had a abnormal mixture, lean/or extreeme rich condition.. and noticed the car would only build 4PSI of boost Max.
3:- now we pressurized the turbo to check it, b/c I am not expecting a $1800 ballbearing turbo to leak, and what we find, the compressor is leaking all around the edges in the back. Now the nuts/bolts are fully tight, the compressor is clocked and then reclocked and no go.. Suprasport says they don't really mess with the front of these turbos as they come from I.T.S. No problem, I can buy that.
The bigger question is, What the hell are these companies building for the MKIII and are they not testing to see if the crap fits or if the crap works. My frustration is really not on suprasport as they only sell what is provided to them, but what the hell is going on here. We dropped close to $3000 with the turbo/lines/I/c/Pipe kit and looks like none of this shit works, not to mention weeks of labor trying to figure out where the problem is.
Now Greg and company from suprasport have been helping us get through these issues as we find them but I want to find a way to bring the heat to the company that supplied these parts to suprasport in the first place. B/c the MKIII is a 20 year old car, its acceptable for a company to put out substandard parts in the market?
I purchased an I/C & pipe Kit from a group buy about 6 years ago from the old SOGI days and til this day, I have yet to have 1 leak or 1 crack in any of the welds and the fit is 100% true to a MKIII.
It just seems to me the standards are differnet today then they were 10 years ago!
