HP and torque will vary based upon pistons, head, cams, intake and all that other shit.

There is quite a bit involved in building a hybrid motor like this. make sure you know what you are getting into. It is possible to just do the correct mods to the head and put it on the stock B20 block. But you cant hope to gain the power and rpm range that a true VTEC motor has. your still limited by the stock bottom end.

A good/reliable build is not cheap.

- Sun Jan 20, 2008 2:08 am #38393 I once had a b20/vtec swap in my ej8. as for trq and hp readings.. from a ebay 4-1 headers with 2.5 inch collector into hi-flow cat and a custom 2.25inch exhaust pipe, and your average bolt on ebay cold air. Skunk2 pro series manifold. I brought it to a local dyno shop with a wide band reading, I had a good ole 185whp with 163ft lb. not a bad thing for soem cheap bolt ons and a stock setup. then I added a Apexi Vtec controller and with some slight fuel/air tuning, I jumped up 10whp and a good 5ft lb trq. So basically, if the block is clean with no type of damage, youre going to be throwing the same numbers...

as for what you need... I suppose the link on top will help you!
