Compression test, fuel pressure test, timing, spark plugs, ignition lead and coil tests, a/r ratio's, test all connections and coolant temp sensor as well as o2 sensor, exhaust system check, blocked cat, waste gate actuator, boost leak?

Could be something simple mate, you know what i did once, when i was young and inexperienced, i dropped in a new motor, new intercooler and pipework.

Put it all back together, fired it up, would idle, but barely rev, could barely get it to move.

Turns out i had left a rag in the intercooler pipework (before the intercooler luckily) that i had put there to stop dust getting in there. Such a simple thing, took me about 3hrs to think of it!

Took rag out, engine was fine.

90kW i'm assuming the engine is having trouble even reving?

      Neil's R33 Gts-t Build

      By Victory · Posted

      All I can say Duncan is good luck and I hope that Neil did not run any E85 in Cheryl. I have recently experienced the full spectrum of fuel tank issues in my R33's that had been caused by E85 and contaminated fuel. When you take the cover off the top of the tank and have a look inside you will get an understanding of how easy it will be. Best case situation is clean fuel with minimal contamination. My GTR was like this and it was a very simple operation to just grab the fuel pump carrier bracket and slide it up and out of the tank. My three GTS_T's had different levels of fuel contamination that was probably caused by E85 in the fuel.  In the worst case all of the metal components in the tank had rusted to the point where there were pieces of rusted metal swirling around in the tank. This required the removal of the exhaust, the tailshaft, the complete rear cradle and the fuel tank. The components in the tank were that rusted that it took days to get the fuel pump carrier and the mounting brackets out of the tank. When the tank was finally cleaned, everything inside the tank had to be replaced. With the tank all back together I could then reinstall it in the car along with everything else that had to come out. Good luck and I hope that you find a clean tank.

      It is a two door. It is black and also still has the OEM wheels and stereo. Exact model would be KR_R32RGFEL_SS According to GTR-Registry.com is a 2 Door Coupe; RB20DE; 2WD no HICAS; MT.F5; (11L) Projector Headlamps and Fog Lights; (12_) Electronic Active Full Auto Air Con (Climate Control); (13-14SS) V Selection -- Which seems to be accurate description of my variant. Will try to upload a few pictures soon. The OEM wheels look like the below image. Image is taken from the goo-net-exchange website.
