Got a friend with an 02 RSX-S and wants to go TODA all-motor, but can't decide whether to get spec A or spec B. He knows spec B will be more aggressive, but how much more horses would it produce.

Toda N2 = (spec A) only with camgears and basic three, fuel system, tuned

Spec B = with camgears, pistons, springs, retainers, timing belt, basic three, FUEL system, tuned,

 

If horses is all he wants why not the vtec killers? Or are they not made for K series yet? Might as well get Bs.

 

You are misinformed about N2 cams. Cam gears have nothing to do with N2 cams. I don't even think they still offer Spec A's because the N2 replaced them. Toda claims 9whp gain over the Spec A's with the N2 series. I don't know anyone who is running B's or C's.
