Well, just like the topic title says. What level should it idle at? Is there a difference between any of the SR series? I couldn't find anything on zilvia search or google search.

you guys know you can adjust idle right? my s14 sr was idling high and i lowered it to 800 where the fsm said it should be and it runs great.

Also depends if you have updgraded cams, that will usually mess up the idle up. Before I upgraded my cams, my car used to idle around 750-800rpm, after installing the HKS step 2 cams along with Apex'i metal head gasket, i had to adjust the idle at 1100rpm with tune (power fc). It's even a pain in the ass when you have the S14 VTC enabled, but with some fine tuning and adjustments it can be done :)

My buddies SR almost stock just upgraded turbo and power fc, idles around 900rpm when warm.

Yah I run 900rpm with HKS 264 step 1 with PFC.....

Lightened flywheels really don't help though..... Really bogs the motor when clutch in

He says there is nothing wrong with it. lol. It is a black top. My guess is that he just doesnt have it turned down all the way idle control screw or whatever its called. or he just needs a tune.

Mines anywhere from 900-1500, tis strange and I don't enjoy it.
I think it's my AAC, but i'm not sure what should be hooked up to. The two 90 degree valves coming off of it, anyone feel like helping?
I've tried looking through various online manuals but it seems they're all missing the important pages, and I don't know how to fluently read Japanese.
Anyways here's a little pic of it, thanks in advance.
