My 2G 4g64 turbo conversion is throwing a P1105 CEL. It looks like the 97 GSX ECU I swapped into my 98 Spyder GS needs a Fuel Pressure Solenoid. What have all you other 4g64 turbo builders done with ECU pin 3 requiring a fuel pressure solenoid? Thanks.

Its getting too cold to work in the garage and I'm heading indoors. I'm going to play with my 3D scanner and see if I can replicate some needed/rare plastic parts. Shoot me your ideas on what to scan and I'll see what kind of success I have.Here are my ideas: - Screw cover for the door panel...

Thank you! I'm almost done :)

Hey August578, one last question, where did you connect the bypass valve vacuum line to? We don't have a dedicated port on the 4g64 intake. Did you tee off the FPR or the solenoid valve? I have a spare 'P' port from the 4g63t throttle body I swapped in - but I read that it might not work.

Thanks Derish. My 4g64 intake doesn't have as many ports as the turbo intake. I was going to put a Tee on the Solenoid Valve line or the FPR. However, I thought, if I have a spare 'P' on the throttle body, it might work.

I am almost done my 4g64 turbo conversion. That last thing I need to do (other than the downpipe to the exhaust) is connect the bypass valve host to the intake. I used the 4g63t throttle body. Can I connect the hose to the 'P' port? It's currently unused and capped. If not there, do I need...

I took a look at 63 water pipe. Don't think it will fit. I'll try the T off the heater lines idea

What did you do for the turbo's cooling lines?

Front right corner. Its on the bracket that has the coolant reservoir bottle.

In case this helps anyone, this is what I did. It seems to work. Wire in a wastegate solenoid and run the red-yellow wire on pin 1 to pin 11 on the ECU. Then tap the red wire on the MAF for the red wire on pin 2 of the wastegate solenoid. I confirmed the wiring using the circuit diagram and on...

Just in case you wanted to get rid of that CEL, this is what I did. It seems to work. Wire in a wastegate solenoid and run the red-yellow wire on pin 1 to pin 11 on the ECU. Then tap the red wire on the MAF for the red wire on pin 2 of the wastegate solenoid. I confirmed the wiring using the...

Thanks! I've wired in the knock sensor and done the fuel relay bypass. Going to do the injectors and give it a try. Did you put in a boost gauge?
