I just spent the last 3 weeks installing my custom turbo kit. I've ran into every problem in the book times two. My setup includes:
t3/t04e 50 trim
internal wastegate 9 psi
crappy muffler shop dp, intercooler piping, and intake.
starion ic
cheap bov
300zx mafs
370cc injectors
jwt ecu
jgs log manifold.
Walbro 255lph pump

I finally started it up yesterday and it ran like it did when i rebuilt my engine. Running like the timing was retarded drastically. It wouldn't rev, and the idle was practically ripping my mounts apart. It ran perfect before I put the turbo on. I've messed with the vacuum lines a little. As far as i know the small line from the bottom of the tb runs into the uncompressed along with the breather on the valve cover. the medium sized one runs into the compressed air. I've found small leaks and fixed them all. My egr block off plate is sealed. I've double checked the 02 sensor, 300zx mafs, timing, leaks. my boost gauge now reads less than 10 (units) for vacuum.
My problem is I leave in a week and a half for college and I need a fix... quick.
Some things I thought it might be are the bpt valve somehow.... i didn't remove it. A vacuum line mishap. or an injector problem. I think the muffler shop also might have hit the vacuum canister. What kind of a problem would that cause?
thx.
