Engine (inc turbos, inlet etc), gearbox, prop, diff, driveshafts, brakes from 1994 UK spec TT. ECU (AKA ECM), engine loom, igniter, ballast resistor from same donar. UK spec air intake box, MAFsensor, fuel pump, fuel computer, rad shroud, supplementary elec rad fan, all sourced and installed. Turbos are standard UK spec items, refurbed & rebuilt by Turbo Dynamics. Original (Jap spec NA) pwr str pump, air con pump, alternator fitted. None standard parts: Cat bypass pipe installed, to Blitz NUR spec exhaust (the hole in the cat bypass for 2nd oxygen sensor is bunged up with a sensor from the NA car, but not connected to anything). HKS plugs (they were already in the TT engine). FMIC. HKS SSQV dump valve fitted in place of the traction control sensor/motor, the electrics to that sensor have been cut off.
I thought that the electrics to the traction control sensor/motor only influenced traction contol and automatic box - as I have neither, thought I'd be okay there. Thought that the 2nd oxy sensor had no effect on performance (?? not sure on this one), so didn't mind being without for a while. As for the crank and cam sensors..they're all in place and working I think, so could I have put the inlet cam on incorrectly (180 out?) when i rebuilt the engine? Would it give the symptoms I described in my 1st mail?
