one problem, two cylinders dont fire at the same time well they do, but not both on compression. One is firing at the top of the compression stroke while the other is on exhaust. This why the spark set up is called "waste spark"

Actually, I stand corrected, the later ones are only 3 wire also. Dont know why I was thinking that they were 4, either way, back to what I said before, the Turbo O2 can be used on the N/A as long as you hook up the sensor output wire and not one of the heater wires, but still a good idea to use...

Yeah, I know all that, I just thought that the early one were 4 wire also. didn't realize that they were 3.

Why do the earlier ones only have 3?

Sinple green works good also, but Dawn is cheaper.

Yeah, turbo is a 4 wire. A turbo O2 can be used in an N/A if you hook up the additional wiring which is a sensor ground, a 12v ign. hot and another ground. You can actually get away without hooking up the 12v and extra ground cause they are for the heater and it is not needed but is a...

Your speedo is off. reading fast. 4.30 rear, W58 trans, stock 225/50/16 tires. RPM = MPH 5000 = 85.9 5500 = 94.5 6000 = 103.1 6500 = 111.7 The equasion is (tire circumfrance X eng. RPM)/(1056 X trans ratio X axle ratio) = MPH

For the FFI, turbo to IC would still be 2 45deg. and a bit of straight and the IC to TB would either be 2 or 3 90's depending on the IC outlet.

depends on how you are going to route the upper and which intercooler you have. The lower is 2 45deg. for best flow (least restriction). Again, it depends on how you plan on running the upper as to what all you will need. Mine when I did it was using the early intercooler and routed it...

Liquid Dawn dish detergent and a little elbow grease. You know the comercial, "Dawn takes grease out of your way.", well it does. The reason that they say to never wash a car with anytype of dish detergent is because it stripps wax as well as grease. Powder detergents are a deffinit NO, NO...

I might give them a try. Now back to the original question, depending on the HP that you are producing will determin the injectors that you will need. According to the Denso numbers, The early (yellow top) injectors are 295cc/min, and the late (green top) are 315cc/min. if those...

Have you ever used them? If so, how would you rate thier workmanship and quality?

That deffinitly is some funny shit. I too think that I need to print that one. BTW, thank god I took the second option...........

What jet said in his last post exactly, more complicated then it needs to be. no matter what the case is with the 51 is here, it sound like the amp or control unit was bad and the previous owner rigged it to work. My control unit went out about a year ago and I had no AC control, heater...

they will not work. The angle and distance is totally different and also, I think that the hole center location for and aft are different. Making a custom set of solid mounts would be the only way of making it work. I know that the late style (89+) the mount pad on the subframe has a 30deg...

on later style ECU's (gray plugs) if every thing is working, A/C on, no code 51. A/C off then you should get a code 51. If you got no code when the A/C was turned on them you are getting the signal at the ECU. Try this, being that you adjusted the TPS, then do a scan with A/C off and see...

This is very very ture. And yeah I do agree with one of your earlier posts about missleading info in the TSRM's. I cant recall exactly what but I have come accross a few myself over the years.

the TPS "IDL" circuit is really sopost to be adjusted by using a feeler gauge and cheching the continuity between IDL and E2 of the TPS. You should have continuity without the feeler gauge inserted and no continuity with it inserted. I dont remember the exact gauge thickness off hand. I want to...
