S14 SR20DET running weird... over 1 yr now

[DriftVader]

hey guys so i seriously need some help badly. Im stuck in the middle of arkansas with a bunch of V8 mustang fags and no one who knows how to work on SRs. Ive had this same issue on my SR now for over a year and cannot figure this bitch out. I recently thought it was the head on my motor that was causing my engine to run like crap. Went out and bought another S14 SR and dropped that bitch in and im STILL having the SAME issue with the car. So heres what ive done:

- Changed the ECU from black WC to Red WC and tried both. runs the same

- Changed MAFs out 3 different ones

- Changed motors from 2 motors

- Wiring harness was swapped over from a shop in florida. ( havent changed it out, maybe the issue?)

But pretty much i cannot get the car to run correctly. here is a video of how its running.:wtf:

Thanks for any help or feed back ANYONE can give.

you got bad surge. have you adjusted your bov and checked timing?

i dont even have it hooked up. was gonna mess with boost guage and all that once the engine car normal.

So breaking up upon revving? Checked your ignitor with a known good unit? Volt tested every sensor on the engine? Does it do it at both cold and warm? Checked timing with a gun? Pulled VC off and made sure it's mechanically timing correctly? More information needed if you want us to help figure it out man.

ya sorry, my bad.

Engine was pulled from a running car in japan and was shipped over here and dropped it into my car, so the timing is already set.

igniter i have 2, havent tried the other one tho in a long time. havent checked volts to every sensor. was planning on doing that this weekend. thanks for the reply man.
