I got the GSR installed this weekend.
And I have a few things to finish wiring up, but it runs for now.

Here is my wired setup.

94 GSR Motor w/ Stock Intake Manifold
91 LS exhaust Manifold
Pr-4 ECU
Modified Pr-4 OBD-0 Dizzy
OBD-0 Injectors with Resistor Box
1 Wire O2 Sensor

NOW BEFORE PEOPLE FREAK OUT! THERE IS A METHOD TO MY MADNESS!

I did not have the proper engine harness to accept my OBD-1 Dizzy, I did not have a 4 wire O2, and im broke. HAHA
I needed to get the car running this weekend so i did what i had to do.

(Plus im still trying to break in the motor. So with a lower RPM limiter, and with no vtec, then i wont be as tempted to go over my 4000 rpm rule)

Now I have everything hooked up and running except the vacuum purge solenoid above the map sensor, and the black box under the manifold.

Now the wireing harness i am running had a 4 pin plug that plugged into the 2 solenoids on my LS, Do i just split those apart to run the GSR?

I hope my question makes sence.

Thanks again

 

Dude I hope you don't even drive it for the sake of your poor motor. Its not gonna run good at all with pr4 ecu. Just save up a little bit of cash for obd1 conversion. all you need is the rywire ecu harness which is $100 & 4 wire O2 sensor. Thats all you need. You could find a used O2 sensor even. Wiring the dizzy is easy even if you don't have the plug you can solder it in just use the stock plugs from your old motor

 

btw you don't need either of those things you mentioned because you don't even have the right ecu so its not gonna matter. The black box is for the IAB's but you don't have a P72 so it doesn't matter.

 

Haha, I knew I would get reactions like this.

The car runs pefectly fine as it sits right now. There is nothing really differient about the pr4/p72 ecu mapping.

It will be just fine as is for a little while. Im not hot rodding it around, keeping it under 3500-4000 rpm.
