Heeelp! my engine has given me bolox and won't rev smoothly above 4500 revs, seems to cut out from the ecu as soon as my second stage of boost comes in and won't go above 6000 revs (I'm in a more or less internally standard 1995 r33 GTs-t (RB25))
Could it be the wastegate? Plugs melted? It's fairly spritely up to 4500 and the first stage of boost is fine so I'm guessing the cylinders are ok, and I've recently changed the fuel filter so it's not that. I've not had the car long and I was told that it had been set up for uk super, I've tried metered amounts of NOS octane booster and that's not doin much ( I didn't push it! ) but now this problem is getting on my tits. I had trouble outrunning a fookin CRX last week.
I would be very grateful for any help or ideas
