In short, when I change gear boost just hangs at 4psi for one to two seconds then goes to 6 or so, yet accelerating in gear everything boosts straight to 6.
Basically std r33 with boost control solenoid disconected as it stopped working a while back.
Also having some trouble with idle, sometimes at 2000rpm and sometimes 750rpm.
Idle problem seems to be associated nuetral switch in gearbox, as in idling a 2k I put it and out of gear and release clutch and it drops to 750.
I'm begining to think a tin of petrol and a match might do the trick...
