According to Crower, you can run the stock valvetrain on his stage 2 cams, but you have to upgrade your valvetrain to run the stage 3 cams. Unlike the Toda cams, there's no mention of changing pistons to avoid contact...

Crower's cams are for both the F20C5 and F22C.

Also, according to Crower, there is a difference between AP1 cams and AP2 cams...

What does a retuned ECU cost from Amuse or Mugen? Would I be better off w/ a VAFC2, PnP Harness, and a dyno tune? I would think that a canned tune wouldnt do as well as a truely "personalized" tune.

But, what year(s) do the Mugen and Amuse work on? I have an 01 and didnt think there were reprogrammed ECUs out there for it.

 

Dear lord, the 2.47l stroker kit is available now, Has anyone installed this kit? Couple this with the stage 3 cams, improved valvetrain, and an EMS, and we could have ourselves a n/a monster.

 

That's where I'm eventually heading

After my ITB install and tune, I'm gonna go with stage 2 cams, a valvetrain upgrade (AP2 retainers, not Ti), and a spoon headgasket. A 2.47l stroker eventually, and maybe a swap to stage 3 cams, depending on the streetability. I want a solid 250 rwhp streetable w/o the stroker kit first.

 

These cams won't mess with vtec will they??

 

nope, but you can bet your ass VTEC is gonna hit hard as hell with the crower cams

 

...

 

 

The desired affect is not to have the VTEC hit hard as hell--the smoother the VTEC engagement the better the power delivery.

 

I agree, that's where tuning comes into play. Adjusting your VTEC engagement point to produce the most linear plot is up to your tuner, not the guy who makes the cams
