Dude just cut the wastegate tube, turn it around the other way, and problem solved. Oh and what's your spark plug gap? Most people run the NGK BKR7E's (part 6097) gapped at .028-.032

the waste gate fitment is fine. i can put a dump on it and have no problems with clearance that what i was trying to explain to that guy, but that's exactly what i am running. gapped at .28

-runs and idles fine
-black wire cut
-new plugs and gapped at .28
-o2 are good
-igniter good
-knock sensors good so is the tps.

im no expert on turbo setups, however I have to agree with Tavarish. That install of the Mani with turbo and WG looks to be upside down.

Hard to see that only 3 ppl have pointed that out. Does/Can anyone provide proof that either old school mani's or any mani in general were made to be mounted in this fashion?

nah, I agree with Tavarish, but I'm letting the guy do his thing how he wants to.

Cam Angle Sensor is an option, but I already connection tested mine and Resistance checked them. Both were near the same in ohms, so I figured both couldn't be bad in my case (one ecu works and not another).

Ok, My car is a 92-93(i forgets), BUT I checked the Tag that was on my Half-Cut, and it says FA05 for the Trim, so it appears I have an 05 motor. trying to locate which wire is cut now. . .

edit/update: I found the wire to cut, cut it keeping the S-AFC connected and using the PFC instead of the OEM ECU, and...VICTORY (kinda).
so then I got rid of the S-AFC, AVC-R, AND OEM ECU to run the PFC only...FAIL
After fiddling around a bit though with the PFC's settings, I had to recalculate my injector %'s from before due to lowering the fuel pressure, and I had to activate the Boost Control Kit to use the Apexi MAP Sensor...NOW I CAN REV!!!
It was pin #10, on the white connect Next-To the orange clip. Since my motor was a 95, it was black and next to brown.

start checking the year of your motors.

Side Note: I now have the Low Oil Pressure Light how do I get rid of that?

WTF. My 1jz has one map sensor, just a sensor with 3 wires with a vacuum going to it. I dont know what those other 2 are.
