OK, so after a closer look at your first photo I realise that while the body of the TCS throttle is present, the motor isn't really there and it looks like the TCS TPS is not present on the back. So you should not have any wiring coming out of the three bolt cover on the front, or on that block of alloy on the back. That leaves just the main throttle body (the part closest to the plenum). To the best of my knowledge, the main throttle body and its TPS is the same between TCS cars and non TCS cars. What do you mean by "the throttle body has two plugs"? The main throttle body TPS in your photo clearly has one bunch of wires coming out the TPS on the front, and these should go to a loom plug at the front end of the plenum, as I described above. You show that grey plug with 3 wires, but you do not say where those wires come from, apart from "out of the throttle body". But where on the throttle body? Are you sure? As to the driving behaviour. Are you running >10 psi? The stock ECU will chuck the shits at you based on the inputs from a number of sensors (the AFM and the boost sensor primarily) if it thinks you're pushing it harder than Nissan wanted, which is not very hard at all. If you are, you should really have Nistune in the ECU. -
Hi thanks for the response so the engine is a stagea neo turbo, it has one tps sensor with 2 plugs coming out of it. The engine was complete as in picture. the loom installed is from a previous car that was a r34 gtt non turbo loom converted to turbo loom. have zero fault codes, have the odd occasion where the 4wd light flashes, and the slip light flicks on full throttle only. Currently running a stagea turbo ecu. its a mix of everything 😂 its runs good just full acceleration the car hits a wall and backfires. But if throttle is feathered in will go redline. in neutral will hit redline no hesitation. did notice the rear attessa pump was really hot as burnt my hand from it not sure if it is meant to get super hot. what i need to know is on non tcs cars is there only 1 plug with 3 wires? the car itself there is no tcs switch was originally r25de non turbo manual 4wd. -
Hey OP, wheels look good, previous owner had the right idea, drive and enjoy car -
I also found that entirely dead ones with maybe a little cord showing sound exactly as loud as brand new ones.

If it actually sounds like this, could be a blown head gasket. Not having any overheating issues are you?
