My buddy who lives across the street has a 93 GSR, and swap it out for a H22. It was funny, but now it's just scarey, that was until I got drive my brother stang. The GSR was quick, but my buddy told me that for serious mods, it would be more cost effective for the swap(than again he did the swap himself). As for you mustang, it's way more fun to drive, and the only thing you won't past is a gas station. For racing Ricers, it's good, but don't try racing any serious guys.
