It's all about money. I own two del sols ones my every day driver with a d16z6 W/cam and bolt on's pushing 170 hp and it is cheap, quick and reliable. My other del sol is a work in process and im trying to get a K-series in it (wich is the cream of the crop honda engine) I've seen honda's with up to 750 hp on the strip but only 400 hp on the street.
