1990 SC

i just picked up a 1990 SC for, 2 hundred bucks, it's not in bad shape, but does have a blown motor. interior decent, no keys, and now no steering column, body not bad, has a few dents. my question is when i rebuild the motor, what can i do to it, for a little more performance. kind of new to the SC stuff, so all i know is what i've read and i understand you have to keep the compression down on SC engines
i'll take some pics to post later. thanks

Re: 1990 SC

You can get a 15 lb boost but it will cost you a $1000,00. +. They only run in the low 15's
a 3lt. S.H.O. eats 5lt mustangs and super coupes. you have to rebuild your original engine.
a regular 3.8 is not the same engine as the super coupe. the 3.8 in the S.C. is a little
under powered for that size and weight of car. And NO don't think of putting a 4.6 in there
it won't work. Do you have an automatic or standard transmission ?
