Hi guy's.I just put a 87 turbo 2 motor into my 87 rx7.But my problem is that my temp gauge gous up to hot and the rev limiter gous on.What can that be? Id like to resolve this problem, i dont whant to drive the dam car with the rev limiter on.Only when i red line it,lol.And all that happens when i just put the ignishen on.

 

did u use the t2 harness? because u have to switch wires for your guages to work

 

So your car is overheating and the low coolant/low oil/redline buzzer goes on?

humm...

 

No it's not over heating,only when i put the ignishen on all that hapeens .I did use the turbo 2 harness.What wires do i have to look at and switch.

"You also have to do a bit of rewiring for this to work in the 87-88 cars (in the 89-91's it is a basic plug and play).

"You have to run 2 wires from the back of the alternator inside the cabin by the ecu. Compare your old NA wiring harness and trace the wires that used to be at the alternator back to the plug they ended at (one of the 2 large orange ones inside the car). These are black and white wires. Now compare these pin positions with the current harness. Cut (or remove and re-pin) whatever wires are presently there (theyre not doing anything important) and splice in your 2 newly run wires. Be sure to cut and insulate those old wires, so you're not backfeeding through some other circuit. This keeps all your idiot lights from staying on all the time (this is normally an indication of a failed alternator, and the car thinks it has failed because the wiring was missing).

"You also have to run 1 wire about 6 inches. On your old NA harness, find the yellow/red temp sensor wire that went under the oil filter. Now find it's pinout position on the orange plug that was inside the car. Compare this to the turbo harness' plug. Now trace the same wire on the turbo harness in the car. Cut or re-pin that wire on the *engine side* of the turbo harness, and jumper it over to the wire that is in the pin position the old NA harness had the wire at. Be sure to cut this old wire and insulate it to prevent backfeeding through that circuit. Now your dash temperature gauge will work like stock."

 

Are you talking about the tow wires that have a plug??That's connected to the back of the alternator???

 

That's the first paragraph.

Second paragraph is a different wire, which will fix your stock temp gage.

 

Thank's for the help,i got it

 

Ok i have another thing,were is the plug for the resistor on the turbo2 harness???
