UH- NO the B16 is WAY better than the p.o.s. LS engine. For one the B16 is about $1,500, and the LS engine (B18B) can be EASILY found for $500. Plus you loose VTEC. Anybody that installs this engine in place of the B16 is a MORON. The only way its beneficial is if you do a LS/VTEC swap. which apparantly has not been done because it would still have the B16 head on it. What has happened is the car was totaled and they sold the good motor and got a CHEAP garbage motor to fill the engine bay because the LS motor uses the same mounts as te B16. BUYER BEWARE. You should be able to find a 99-00 SI for about $6,000-$8,000 and not have any worries about it. I know it sounds like alot, but with that engine you may as well be buying a EX model. Along with the body damage and everything else you can expect to pay about another $5,000 just in parts and labor to get it running and looking correct with a salvage title. STAY AWAY!!!
