Swapping a 2000 C4 Motor Into A 1999 C2 - 2 Question Throttle Body Fuel Cooler

Recommended Posts

Hi All,


I am in the process of swapping a new/used motor into my 1999 C2. I found out the hard way what shifting from 4th to 1st while doing 100 will do to a motor (I was on the track).


Anyway, I purchased a salvaged 2000 C4. I now how both motors out, and after doing some things to the new motor, it will be going into my 99. Right now, I know there are two differences that I am trying to figure out the solution to before I start the install process.


1. My car is a 99 with a throttle cable. The 2000 C4 has the EGAS/Drive By Wire. What is the procedure I need to do so the new motor is using the throttle cable. I know I need to use my old throttle body, but what do I do for the wiring? Do I need to use my old harness? Or can I modify the harness that is on the EGAS motor?


2. The donor car has the fuel cooler lines attached to the AC compressor. My 1999 does not have this set-up. How do I adapt this? Ideally, I don't want to have to use the AC compressor from the donor car, because I know my compressor is almost brand new. Is it possible to eliminate the fuel cooler lines from the 2000?


Any help would be great. Thanks in advance.
