My good friend has an s13 red top sr20det (40k miles, coil ignition) in his 92 240 hatch coupe. We did the swap ourselves about 4 months ago and it went pretty well. Mods are an apexi n1 turbo back, kts? front mount kit, hks ssq, intake, and safc ii (untuned), new timing cover, greddy head gasket kit. The car was running mint for the last 4 months, just a little rich cause its not tuned. The car wouldnt idle without your foot on the pedal though. We had a blitz bov on there and found out that it was leaking. We replaced it with an HKS ssq. Then we noticed it was ticking a little bit at 1500 rpms and it sounded like ****. (this is all about a week after installing the safc ii) Also oil smoke was coming out of the breather. We checked the plugs and they were ****. We replaced them with denso iridiums. Now the car will idle but it goes up and then almost stalls continuously. And smoke comes out of the breather on the valve cover everytime it almost stalls. If we keep it at 1500+ rpms it ticks a tiny bit and I dont know if its valves, cams or what. I dont want to drive it and hurt anything. Before I pull the cover I wanted to know if anyone thinks they know whats going on with it. I also had my dealership replace the throw out bearing a week ago because it blew. It was running strong though... Would the breather replacing the vacuum hose be doing it? SR20 gurus help!?!?

 

the breather filter wont make it act like that. make sure you check all vaccum lines throughly. any leaks and thats a good possiblilty. if you decide to pull the valve conver just make sure you done ruin the gasket. its a rubber gasket and can be re-used. and theres nothing that will hold it upon removal. just undo the screw/bolts and take it off.

sounds like to me(and i could be wrong) but adjust teh timing. if its stalling out like that.

 

It sounds like a timing problem to me, especially since it's not idleing correctly/ stalling

 

I would also go with timing on this. As far as the ticking is concerned, I wouldn't be too worried about it. My car has slight tick and every SR I have listened to out here has had a slight tick to it.
