We have been trying to get my friends sr20 running for the past month and a half. The car was running fine before we brought it into the garage.
So it was a bone stock SR that ran amazing. We upgraded it with a 2871r, jw s3 cams, 750cc top feeds, and we modified the stock exhust mani to run an external wastegate. The install went fine, cam timing is 100% correct.
But heres the problem the car will only start and idle when it sits over night. As soon as it warms up it will not idle without staying on the gas and a very bad miss. And as soon as you try and drive it once you get into any boost it breaks up really bad. The car also has bad vaccum right now. Its only at ~11 in/hg as opposed to before when it had ~16-18. And I cannot for the life of me find a vaccum leak or boost leak.
The car is also running VERY rich which I assume is from it missing.
WTF is the problem here? Its driving me and my friend absolutly nuts.
Oh and btw it has an enthrpy tune on it which was takin from a running car using the same setup.
