Well before you read this, I should tell that I'm kind of a noob, but I know some stuff about the supra. My friend just got his grampas old car; a built supercharged regal. I know for a fact that it's fast(yeah I know, not your average buick). His mods are an intake, LS1 corvette throttle body, Z06 Corvette MAF, header, 3" down pipe, high flow cat, 3" cat back, ported supercharger intake manifold, supercharger pulleys, whipple supercharger and everything tuned up to 18PSI with a crazy suspension set up. My question is how much money would I have to spend and what would I need to install to keep up/take on his regal? I have a stock 88'' 5spd turbo that's pretty much stock and one really competitive owner. LOL. Any help?
