i recently fitted a FMIC kit to my r32, when we pulled the pipes off they had noticable oily residue in them. Is this normal?

Also car seems to be hesitant to rev after 4000 and only really revs to maybe 6000 sometimes.

what could be causing this? as im new to skylines (pistons actually)

How much oil is there? My supra has an oily film\residue in the intake piping aswell and have been assured by other import owners\mechanics that it is normal for turbo cars with a fair bit of mileage. If there is heaps though it is most likely your turbo seals are gone and they will need rebuilding.

Does your car blow any smoke?

got told this morning by my mate that when i took off there was smoke (black) coming out of my exhaust. But when it warmed up, no smoke. really only because i had just started it that morning.

black smoke is normal = running rich.

i have always been under the impression alittle bit of oil buildup in the cooler pipe was ok

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
