okay ive heard its possible, but i know nothing about honda motors. ive been thinking about buy this motor. eBay Motors: 92-95 HONDA PRELUDE SI DOHC JDM ENGINE - F22B (=H23A) (item 260095050744 end time Mar-15-07 16:41:03 PDT) 160 hp for 500 bucks vs the h22 200 hp for 1000 bucks. but its not vtec, so what all does it take to convert to vtec? and then what would it put my hp at? or would it be cheaper to just buy the vtec h22 for 1000. keep in mind i have to buy a ecu no matter which i go, and i have to build a custom wiring harness no matter what motor i go with.
