so apparently rsx-s tranny bolts up to f20...
i was over on H-T and saw this:
pretty interesting. It was only a matter of time before someone gave it a shot. I just think it's funny that no one, including myself, thought it was possible. Since the s2k is rwd. (well, apparently these guys thought it was possible)
so who is gonna be the first to step up to this one?

True I love a nice mid-ranged and top end car.
K24= 160 lb/ft @ 4000 RPMS & 166 hp @ 5800 RPMS
F20= 162 lb/ft @ 6800 RPMS & 237 hp @ 7800 RPMS
F20=TOP END!
K24 doesn't even know what that is. F20 has a 8000 RPM redline. Nuff said.
F20 flexed hard on my 2JZGE from 70-125mph. SIIIIICK top end.

Rep Power: 0 I wonder if the gearing would be appropriate for the F20 and if the tranny can hold up to all the higher revving.
Also, I thought the F20 had a 9000rpm redline and the F22 (the 2.2L in the latest iteration) had something like 8600? or something to that effect?

i was comparing my car... and basically, you can compare my car to a tuned tsx motor
f20 revs to 8900 and a f22 is 8k

Rep Power: 330 there is no original story, the thread started off as a question whether or not the f20c head would bolt up to the k20 block. Then someone suggested swapping the whole motor and those pics were posted, the first one is going into a lotus i believe.

The figures I quoted were directly from Honda on 2006 Spec 2SK & an Accord
I doubt you have more HP than an F20 at 7.3K
I am not trying to sound like an ***, but your claiming your K24 swap to be the unbeatable against a motor that is proven better than almost EVERY Honda & Acura N/A in a race without heavy motor work.

Rep Power: 0 torque and proper gearing > all top end
any street driven car will feel better with some torque, I'm with hondaluver, besides, there aren't many modded K20s that still have 160whp, boltons, cams and hondata will put you neck and neck with an F20 easily

I doubt that the K24 will keep up with an F20. The F20 is a little over 200 at the wheels with no work what so ever.
Let's not forget the fact of power to weight ratio too.

Rep Power: 296 I have heard from several people that the F20 head and K20 heads are interchangable. Judging from pics of side by side HG comparison it looks to be true. The K20a and a2 heads are supposed to be better than the F20. K20 head design contributes to most of the engines efficiency. I wouldnt be surprized if there are a few reports of guys with stand-alones doin k20 I-vtec setups on their S2ks. Think about it, K20a head K20 ITBs, if the S2k header flange is different, the port spacing is almost identical so a flange swap wouldnt be much work or a custom header and lots of dyno time could be done, nice set of TODA cams or something, Rewired harness for K-pro or AEM, improved I-vtec could possibly turn an S2k into (more of) an all motor monster. Maybe Im reading too much into this, hehe.

power to weight? ... k24 civic > s2000.
on another note ... in my opinion, an f20c would be a nearly useless swap if you're planning a fwd car. a built k-series motor would make ridiculous power... check out the latest honda tuning (is that the right one?) mag ... there is a built k20 making just over 300 whp n/a, revving to 10000 rpms.
seeing as how f20c ecu's can't be modded, I would think that it would be very difficult to be able to tune it properly

With respect to a race:
The AEM EMS solves tuning for the S2K (AEM part# 30-1052). No problem then.
The S2000 only weighs 2855, a K20 swapped EM2 weighs about the same.

True-a swap SHOULD reveal more power than the original motor in the car because why would you swap in the first place....ya know?
i.e.-K20 in a EM2 > D17 in an EM2
The curb weight, just taking that alone into account,
The Type S is 2840 lbs
The EX Civic is 2597 lbs

curb weight for an 01-03 EX is 2550. 04+'s are about 50 pounds heavier. But then again, not everyone swaps into an EX civic either, so weight is pretty variable. How does adding a K series motor add 300 pounds on top of the D17? it adds 150 pounds at MOST.
I never said anything about the f20c in an em2 either ... perhaps other people, but not me. I'm talking about K em2 vs. s2k
hmm, I didn't know the ems was out for the s2k.

the F20C would only be faster because of the rwd advantage and the ability to run much wider tires.
however, given a fwd built f20c (like the one that was originally posted here) and a built K24 frankenstein, the K24 would always come out on top.
C'mon .. even you know that there is no replacement for displacement
I could be wrong, but I haven't heard of any drag cars running built F20C motors in the 9's n/a

you would prob have to reverse the cams if you want it to work...

someone should build an awd k24 frankenstein turbo using element awd components. that would be something really noteworthy.
