vtec to i-vtec conversion<--fantasy?
hey honda heads, ran across a web site that said that a d17 ex could be made i-vtec with alot of work, and would theoretically(sp?) produce 140hp...any thoughts? i don't care if its a alot of work, i think i might like to do it...unless its totally unreasonable.

Rep Power: 424 I don't think you can just plug something in and get the VTC. Its far more complicated than that. The timing advance and retard range on the K series is simply amazing. I don't think its something you can accomplish with a single cam anyways, there's not enough room for variation.
Don't drink and post, you will end up hilarious.

2) to the best of my knowledge, the K series motor spins the opposite direction of the D series,
3) You can have a D17 ECU, or a K20 ECU, but not both (to the best fo my knowledge), the K series head would require specific functions of the K20 ECU. While the rest of the car would need the D17 ECU to run correctly. This is not a straight foward swap like a LS vtec, this is completely different.
Theres a slew of reasons why this swap wouldn't work. You'd have about the same chance of success trying to moddify a b18C5 head to fit on the D17, its just not happening.
