I was just visiting with a friend who is restoring an 88 turbo coupe that he has owned since new. Nice job on the body, now he wants to make it breathe a bit better. Can someone please offer some suggestions for performance upgrades in this motor? 120k on it, Mobil 1 since new. Everything from mild to wild will be considered. Specifically, any computer related enhancements, boost raising ability and overall hp gaining mods. Also, suggestions for speed shops or wrenches in the Boston area, or web sites that cater to these engines
Thanks all!
