Looking at the wiring diag. posted for the timing control, wires IGt and IGf coming from the ignitor are cut and rerouted to the maft pro. My question is after the rewire IGf on the ignitor is not reconnected, Is this right? the wiring diag can be seen at...

Has anyone addressed the cel when disconnecting the NB O2 in order to use the PT Tracking?

A while back someone posted a pic of an engine wiring harness and had all the connectors labeled and I searched high and low for that post. If anyone knows of could you let know? Thanks

I had to replace the plastic connector on the harness side of my O2 sensor. I think I may of F-ed up the wire order. Can someone let me know which wires on the harness correspond to which wires on the O2 snesor? Any help would be much appreciated!!!

Does anyone know if the return line on the turbo flows freely or should there be some resistance when I blow thru it?

I have water vapor comming from the breather tubes on each valve cover and was hoping for some input as to what might be going on. The engine has a fresh rebuild and we used a cometic mhg and arp bolts. The oil is clear and the coolant has no oil in it. Please help

I just installed a new walbro fuel pump and eliminated the fuel pump relay and resistor. Im using a maft pro set up and had things tuned pretty well prior to the upgrade. Now with the new fuel pump my afr is below 10 at idle. Is this common when doing this upgrade? Do I have to start...

I have an 89 turbo with a new rebuilt 7m engine. It has arp bolts thru out, a cometic head gasket, maft-pro set up for speed density, RC 550 injectors, waldbro fuel pump, and cold air intake. I was thinking of up grading the turbo to the precision sc61. Has anyone used this turbo? I'm just...

What are people doing to improve spark. Aftermarket coil pack?

Hope this is the right area to post this. I'm finding that when the front fan is on when I try to start my car the engine will not turn over, then I turn the a/c off (the front fan goes off shortly thereafter) and hold the key in the start position for 1-2 seconds it turns over and starts. If...

I just rebuilt my 7mgte, ran it for about 600 miles, took the intercooler line off the 3000 pipe and found oil in it. Does this mean oil is blowing past the bearings in the turbo? (no oil found in the intake side of the turbo)

If the cam position sensor is off by 1 tooth, how much will the timing be off? Will the car still run? I had the engine rebuilt and tryied to time the engine but I could only get 5 degrees btdc before I ran out of adjustability. BTW I have 89 turbo.

:1zhelp:I am rebuilding my 7mgte and during the process we took .010 off the block and .010 off the head. We also reconditioned the rods and only lost .003 in length. According to the actual specs I should use a head gasket with a thickness of .036 to achieve a compression ratio of 8.4:1...
