Hey Tampa Racing.

I just got my hands on a 91 Supra with the Stock 7m-GTE. About 300k miles, but it's all one hundred percent stock. Really good find, if you ask me (aside from the mileage). Anyway... There's a huge boost leak. I can tell because of some obvious symptoms, and the classic big ass puff of black smoke coming out of the exhaust after boost. The previous owner said that the Turbo has a lot of shaft play, and that's the ONLY problem with the car. Let me know if these symptoms sound normal: I can't push the car past 4k RPMS in gear (it starts to sputter and slow down), and whenever I go past 2.5k RPMS and then throw it in neutral, it'll have trouble catching up to a normal idle. In some cases, it won't be able to catch up at all, and it'll just stall out on me, unless I gas it up in neutral to help stabilize it. At first, I thought it was the MAF sensor going bad, so I swapped it out with the MAF from my project Supra. Unfortunately, it didn't help at all, which means either both MAFS are bad, or it's not the problem. The Turbo itself is definitely a factor and will have to be swapped out regardless, but I'm trying to figure out whether that's the only problem or not. I'm also thinking the Intercooler piping may be leaking additional boost, since it's all stock piping, and it's been about twenty years, and a shitload of miles. Could the TPS have gone bad? The A/F ratio is definitely off, and I feel like it's not responding like it should be to the throttle. Any input would be appreciated. Thanks a bunch.
