I am having so much trouble with my TPI I have decided to rid of it. It's a 1988 GTA 5.0 Notchback with digital dash. I built a 350 bored .030 over, have S/R Torquer World Product heads 76cc chamber 170cc intake runners, flat top hyperutectic pistons, block and heads decked. I bought a 650cfm Holley Double Pumper, Edelbrock Performer intake (87+ heads) and a Mallory fuel regulator so that I can keep my stock fuel pump. Parts are on the way. BIG PROBLEM----- What wires can I rid of in my engine? Do I need the computer to start my car? I have a chip on my key. Also will I need any of the wires going to my distributor? I bought an MSD Billet mechanical Distributor and MSD Digital 6 plus Ignition Box. I have a digital dash and I want to try to keep it working. What wires from the computer control my dash if any?? Also, what do you guys think about the prducts I bought-- good or bad choice. I have and Elgin Cam int .462 exh. .470 lifts and degrees are 210 int and 214 exh.

 

I love carbs just as much as the next gal..but why the hell would you do that?

What could possibly be so wrong with your TPI that you would lower the value of your car? Besides...this swap isn't exactly a walk in the park..it seems like it would be more effective to just fix whatever is wrong.

 

This swap is not as hard as everyone makes it seem. I just got done about a week ago doing the same thing. It is really quite simple. To keep your dash in working order you need to keep your coolant temp sensor for your guage and the two wires running to your coil straight from the harness and not the ones coming from the ignition control module. these to wires will hook up to your new coil, one is battery power, the other is reference for your stock tach. Leave the wires for your fuel gauge going back to the tank and if you use the same alternator your Amp guage will still work. That should just about take care of your dash.

P.S. dont let anyone rag you about doing this swap. Who gives a **** its your car, not theirs!:rockon:

 

What about transmission shifting problems. Are they also controlled by the ECM?
