Did 4 consecutive 1/4 mile runs in my 93 JSpec TT Auto, turbo noise changed.
Reg Reimer & Team at RCTS in Calgary diagnosed it and took some pretty pictures for me! Reg thinks someone fed me a rock while the car was sitting around with its hood up.
1st picture: Don't mind the bugs on the bumper, spent 800km on the Highway to get it to RCTS.
2nd and 3rd pictures:
4th picture: Similar to what should be going in.
I've decided to go single HKS turbo (T04Z), brand new, with HKS Vpro and AFK. Lucky enough that the only shop in Canada who is HKS pro certified is Reg's. Along with a new rad, timing belt, water pump, brakes, HKS Titanium racing exhaust, TRD 320km/h speedo, and a SLD, it's going to be a very expensive upgrade. We'll see how the car handles after all this though.
Plan is to run the t04z 10psi, producing about 400 wheel hp, enough so that I can run stock intercooler, injectors, and auto transmission. Any tips/comments on the build?
