i just recently bought a r32 with a series 2 RB25DET in it. The car was a mess as its had the aftermarket cooler ripped off it and the standerd one put back on but all the vacum lines and the lines to the waste gate were ripped off. The car wasnt running when i got it so ive been trying to get it going. First the car was hitting boost limiter because the hose to the actuator wasnt connected, ive sorted that out but the car is still misfiring under load when the boost comes on. Could this be because of the timimg???? All the lines are in the correct place now and the spark plugs seem ok so do the coil packs. Im a newbie to the turbo scene so any help would be appreciated.
