I'm going to try to give as much information as possible and add more as I remember.
Ok so I have an S14 SR20DET Zenki motor in an S14.
My car runs like complete crap. To start it, most the time I have to give it gas. Idle will go from 13.4- 17 A/F whenever it wants. When I give it gas it hesitates before it revs. When I drive it(out of boost, haven't boosted at all because i'm running stock injectors), I get a fuel cut then it starts back on its own a few seconds later. My crap external waste gate is letting exhaust out of the screamer pipe. Tried a buddies other crap xs power wastegate, same thing (ordering a Tial). I haven't installed my 550cc injectors because I don't have a tune yet (sending to enthapy once I get the car running).
What the car has.
-ITS T3/T4 Turbo
-ISIS (yes I know crap manifold)
-Brian Crower 264 Cams
-Stock S14 SR20DET Maf
-Stock 370cc injectors
-Tial QR BOV recirculated
-FMIC
-XS Power wastegate (with a nice exhaust leak out the screamer on idle!)
-300zx fuel filter
-Walbro Fuel pump
-Cometic Headgasket
-ARP Head bolts
What i've tried
-Cleaned MAF
-Cleaned IACV
-Changed spark plugs to NGK BRK6
-Tried another WC ECU
-Replaced leaking fuel line
-Compression is 150 across
-Previous owner of the wiring harness had an AFC Neo wired in, wiring doesn't look to professional nether.
Today is when I took out my manifold, turbo, ect to try out the other waste gate. When I started it up, it wanted to die when I reved it up and eventually died and doesn't want to start back up now. Does turn over though.
