I ment F22C and TODA... I still don't see how it would not work if you got toda pistions too. From what I have read the block is the same. Heads are either the same or could be worked on. I think its possible but I still could be wrong. Of course we would need an 03 ECU.

May be I don't have that much knowledge, but why whould you need to exchage to 03 ECU to raise redline. Can't you just install rev limit cutter after all those modification on engine. I'm sure it will be lot cheaper that way, except about the fuel and air ratio setting.

Maybe someone can explain this to me. Why does anyone want a 9k redline on the F22C1. Is it just so you can say that it revs to 9.2 grand? Revving this engine to 9.2k rpm is only going to cause premature engine wear. Seems like more cars have around a 8k redline now anyhow. So sky high redlines are becoming more common. Who cares if it is 8k or 9k. What irks me is the loss of 1k rpm in the vtec. I would like to have vtec kick in lower to have the same useable vtec band as opposed to increasing the redline to do the same. Although I don't believe it would be the same useable vtec band since it would be kicking in at a lower rpm when even less hp/tq is available. Anyways just thinking aloud.

You can get a VFAC, it lets you adjust the VTEC crossover point as well as your air/fuel ratio.
The thing is...VTEC doesn't just equal more power. Below a certain RPM, if you have high lift VTEC settings, then you'll actually lose power. Honda chose very close to optimum VTEC crossover point, with a little thought to fuel consumption and emissions (some argue that actual power takes a back seat to the "Butt Dyno"). You may not be able to lower it, depending on where exactly that magic number is.

VTEC killer cams are for racing only...Race cars do not use the lower portion of the rev range on the track. For this reason it is pointless to use the low lift setting (because the low-lift setting optimizes lower RPM performance). This means that a typical VTEC Honda is at a disadvantage to one with the VTEC killer cams solely because its valvetrain is heavier than the latter.
In short...you will complain tenfold about a lack of torque if you remove VTEC from your Honda, but you will feel slightly faster acceleration in the upper RPM.
