Hello There,

I have 1987 930 turbo just rebelled the engine and have new Alternator, Fuel pumps, Alternator Fan, Faabspeed "Headers, Mufflers, Air Intake, Intercooler", Tial W/G with a 1 bar spring, A/C kit.

When i drive the car it cuts of power after around 3900 to 4100 RPM then i replaced the Distributor Cap, Ignition Wires & the Coil Wire with new set and still having the same problem but "more power with engine" as 2 of my Ignition Wires was broken.

Please can any one help me what to do ?

Thanks and Best Regards,

 

Cuts power? As in falls on its face or drops cylinders? Was does the tach do during this episode?
If it falls on its face the over-boost switch may be grounding which is possible with all the recent changes to the exhaust.
If it is dropping cylinders, it may be a fuel problem.
