That was one of those deals. I was swapping that motor into the 325 chassis and messed up the fuel lines. So after about a days worth of getting pissed off and looking at EVERYTHING i could, i notice that was the issue, but to test it out i cranked it over and it fired up and acually idled without the TB, IM, ICV, or even the O2. Crazy little m42's run like champs.
Heres another with only the header for an exhaust. As of now i have an OE boasl repacement, car is dead quiet!
