Unless you know how or know someone who know's how to build a LS/VTEC swap....do it. It is very rewarding. My friend has one built correctly and pulls over 200 hp and gobs amounts of torque proven on the dyno. If you dont... just do a straight B16A or B18C swap. You'll end up spending more if you attempt the LS/VTEC yourself with minimal knowledge of how to build one.
