s13 sr idling too high - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hello Zilvians. I just installed an s13 blacktop and I have having some major idle issues. My fuel pressure is at 51psi running stock boost with an s14 t28 and I have already worked with the idle adjustment screw between the 2nd and 3rd runner and still I am idling too high. What do I do? :hammer:

thanks for reading.

CAS Timing or throttle cable is too tight

First off, lower your damn fuel pressure. Take the vacuum line off it and lower it down to about 38-42 psi. Like stated, double check your timing. Also, you got all the vacuum line on?

With the Vacuuum on, I run about 55-60, but I am boosting 18psi on a 2871R. I guess stock turbo with FPR should't be that high?

Yeah, start with the fuel pressure. Are you using a factory IACV hose? Slightly high idle is usually a sign of air in the cooling system. Have you bled the cooling system yet, the penzoil air bleeding kit that attaches to the heater hose is a life saver.

stock turbo w/ stock fpr shouldn't be higher than 11 psi... any greater than that will blow your turbo...

i should know because a certain someone forgot to put a vaccum line on my wastegate and started boosting at 15 psi....
