Thread: upgrading turbo-need help

so i pulled my ecu out today and noticed that the ecu is programmed for 520cc subies, z32 maf @ 4 bar and turbo with a 1000 rpm idle program for cams. but im not running cams.. could this be an issue?

no it should not cause issues.

so i went and checkd the rail for any leaks, fixed 2 injectors that i had connected backwards and checkd the plug on the coil. went to crank it and it wouldnt start, i tried 3 times, on the final time when i let go of the key it started for a half second then just did a huge defening kaboom backfire. i think out of the exhaust but im not sure.. so now it wont start.. im lost.

fouled plugs and flooded engine. pull the plugs and clean them also make sure their is no fuel sitting in the cylinders. If there is leave the plugs out over night.

ya i took them out and are really black and wet with fuel still, even the cylinders. im leaving them out overnight and changing the oil tomorrow morning.. can i clean off the plugs with carb cleaner?

I usually brake parts cleaner and a wire brush.

so i got some taylor 10.4 mm spark plugs wire, cleand the plugs and drained the oil.. car started right up. no backfires or anything.. i took it out for a spin and it went perfect.. i got on it and hit the boost switch (16psi) and it went great.. car feels strong. after about 10 min a driving i started feelin clutch slip.. i had an act street/strip.. i dont think its going to last much longer... thx alot for the help guys especially cortrim1..

Glad you got the car running good, now go and finish off your clutch.

what clutch should i look for? 6 puck act?

Pressure plate is more important. 6 puck should be good, I just hate puck clutches cause of the chatter and lack of being able to slip it out.


I'm running a stock disk with a hd act pp and it holds onto my nitrous'd VE just fine.
