hi guys recently i just ventured in a turbo change over from a stock rb20det turbo to a vg30 turbo. The vg blew so i put on my stock turbo again but ever since then its been slowly gettin worse. like it runs like a pig when its cold and once warm when idling at the lights or runnin it on the turbo timer she fluctuates between 500rpm and 0rpm and then finally gets to low and stalls it dosnt happen all the time but its gettin more fluent and is startin to get me a lil worried. other thing is when i put my foot down flat to the floor she just so dowey and all of a sudden bam hits me real hardcore still around 3000rpm but before that its nothin and find she is runnin really really rich. I was wondering if anyone could give me some suggestions on this matter on what it might be thanks for your time

Make sure the turbo and manifold bolts are all done up to torque. Did you use new gaskets? If that isn't the problem, then don't drive the car under boost until you've identified the problem as engine damage only takes a 10th of a second if the engine leans out. I recommend taking the car to a reputable workshop, one that has good experience with Skylines.

    • Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.
    • At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!
    • Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.
    • Thanks GTSBoy, i will do abit more digging. I am missing a blue relay near the ECU connector... so i will chase that up in the next few days as well  
    • https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
