Why didn't Honda make the F-series engines with i-VTEC? Everything that I have read thus far states that i-VTEC is a tuner's dream come true.

 

I think because i-vtec was only introduced in 2000/01 and the S was in production in 99 in Japan

And because the S's engine has been voted best in many surveys throughout the years since production they won't change it to i-vtec until it becomes out dated and when they do they are probably going to give the S a full overhaul anyway

If it aint broke. . . .

 

Because honda doesn't want a bunch of S2000's that can make 312 whp n/a and rev to 10,000 rpms running around the street. SCC recently did a N/A RSX-S build to those specs.

 

i think i read somewhere that there isnt room in the s2000 head for the extra stuff. im probably wrong, though.

 

yea, i've seen lots of "300" HP NA RSXs/Sis. C&D super4 shootout cars couldn't even get into the 13s for christ's sake.

a 300HP RSX should run a 13 flat or less.

 

you're right. the cam gear design is too compact. Honda would have to make a whole new small cam phaser; they could not reuse the K series one.

Honda isn't going to do a major redesign until the car is replaced. it costs too much. BTW, the AP2 is not a major redesign.

 

would i vtec make the s better? how?

 

i-VTEC allows you to fully tune each cam angle and thus make the most amount of power while still maintaining a high degree of efficiency.

It really disappoints me to know that the K-series engines have better tuning capabilities than the F-series.

 

Could you put i-VTEC heads on a F20 or F22?

 

Are you talking about having something like a F20/F22 block and a K20A2 head? I have no idea if something like that is even feasible.
