Im hearin a fair bit about the B20-Vtec conversions and their sucesses. well i have a 91 prelude with a B21 and was wondering what id need to get if it could be done at all.

i put a full exhaust on the car adn have been playing with the idea of gettin to some more serious play but seemly the option availible is a swap and i dont go the money for that.

You can do it, but it's not too common, and the geometry of the engine isn't that great either... check out Ludespeed for some information on that setup- he used to do VTEC conversions on the older B20 Preludes.
