Could you put i-VTEC heads on a F20 or F22?
NOPE, Totally different from what im lead to believe

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.
Yeah maybe something like that. Or lift the electronics and mechanical components and fabricate a head that can utilize it in the Fxx motors.

Then, that would probably be expensive as shit.

Basically, is it possible to add i-VTEC to a Fxx?

the k series development is loosely based on the f20c design and the f20c development is based on the f20b design. basically the k series is developed after the f20c, and it is just an improvment in techonology. also it's possible to fit the k20 head on the s2k block but it would take major funds to even comprehend such task. for example the f20c's intake/exhaust cam is driven by a gear that is driven by the timing chain which connects to the crankshaft. while on the k series the timing chain drives the intake/exhaust cams like the b/d/h/most of f (except the f20c/f22c.)

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.
Tuning, maybe. however, with enough money, the S2000 has more potential for peak power than the K series engines.


Also, the K-series was essentially designed FROM the F series in the S2000. The K20 essentially derived from our engine, hence the reason we don't have i-Vtec.

very true

and the f20c development is based on the f20b design.
very FALSE. don't worry you're not the first person to make this mistake.

the F20C was designed from the bottom up, and was not based upon another platform. The only thing the F20B really even has in common with the F20C is the engine code name. Otherwise it's a new engineered design.

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.
1 word...traction

My 176 whp 173 wtq 00 civic EX with factory open diff ran 8.52 @ 82.XX mph with a 1.8 60 foot time. I guess that converts to about 13.2 @ 103 in the 1/4 mile. A 300 whp RSX on slicks should be lmid to low 12's easily

Another " I'm so disapointed in the S2000" rants- who cares - if you don't like it don't buy it - if you have one and are disappointed - sell it. Who givea a rip?

But would the curve be flatter on the K series? Would the peak with a Fxx be enough to outweigh the K motors with i-VTEC?
The K-series would likely offer better room for improvement for area under the curve in regards to tunability.

As for the 2nd question, that depends. Are we talking about leaving the engine in an RSX and an S2000 respectively? If so, then I think if you built both to the same extent to get as much power as possible, you'd still find the S2000 reaching the end of the 1/4 mile first.

At the moment I believe we have 2 S2000's making over 850whp on about 34psi.

That's just it--it shouldn't take a lot of money to make the F-series faster than the K-series. Dollar for dollar an F-series engine should out-perform a K-series. Since we know that isn't the case, I think Honda made a mistake by producing the K-series engine which is a lot more tuner friendly than the F-series.
