the ls motor(b18a/b) is the perfect motor for a turbo cuz it has asuch a low compression ratio my frien jus ran a 12.39 in a 95 civic coupe on the 10 with a ls/ t3/t4 turbo on 11 psi, but if u really want vtec u can alwaqys get a bi6 or b18c1/5 (integra gsr/type r) head and do the ls/vtec conversion and that motor is more powereful than the gsr. peace:smoka:
