c34sr20det

Its got standy T28 ballbearing turbo. Everything basically stock apart from b.o.v, front mount, exhaust and the fuel pump. Think mite have found problem. There is a whole bunch of wires coming off the ecu that go no where. Currently trying to find wiring diagram for 98 silvia jap import. Have only came across 200sx which is nz new version. which has different coloured wires so does not help me.

Hey my c34 with blacktop s14 sr20det in it was in getting checked out. Mechanic found that my fuel pump was only pumping 18psi nd it was leaning out. It now has 500hp bosch fuel pump. It runs better but hot idle is not good and seems to detinate when only just hitting boost. Ne ideas?

Found that fuel pump wasnt pumping enough. Now have bigger fuel pump. It cruises along sweet. But when its hot the idle drops. And seems to be detinating when hitting boost. Any help would be appreciated

Just noticed when cruising along at a steady speed the vacuum will drop down when it starts playing up. And when idling the revs drop and just about stalls but keeps running. Any help would be much appreciated. I'm starting to run out of ideas

Mass air? U meaning air flow meter?

I've got a 98 blacktop sr20det in a c34 laurel. It runs fine when its cold but when it warms up a bit it starts to hesitate when accelerating. And bunny hops. It doesnt like being under load. Cruising along at 50k'z then it looses power if reving to low. chop dwn a gear and gradually build up speed seems to be fine. Any idea's? Its doing my head in
