  1. hi guys need your help over the winter i have done quiet a few mods on my R33 RB25 car like power fc , 550cc, Apexi turbo, external, pump etc on the start the car was running really bad pendling between 0-600rpm i found out it was because of the oil catch tank and after blocking the small hose from the head going back the the plenum this was fixed ( i think) the car was fine for a few minutes at about 750rpm after warming up the rpm dropped to about 450rpm engine running very quiet and smooth after stepping on the gas up to 4000-5000 rpm the engine is reving fine but on the way back to down engine is stalling straight to zero tuck a short drive with it but the engine is always shutting off when i push the clutch pedal otherwise the engine is performing fine... i heared about a AAC valve what needs to be cleaned sitting on the plenum could this be the probleme ? Please let me know im thankfull for any help please ignore my spelling and gramma =) dino
