hello , i am new to this forum but i am getting more and more familiar with my 87 mr2. ok i just bought this car from a guy who raced it in the scca and retired. and already this mr2 has the supercharged top and basically rebuilt the whole engine from up to bottem. i also recieved other heads that are already ported and polished. so my question is how much hp does this car already have from just this. i think i has cams in it as well. but who knows, i want to turbo this car, but not sure how much hp i can run it to make sure i don't ruin the engine .... any info would be helpful. thanks.
