First off, id like to say that the F20C with a rsx tranny looks like it would be a very nice setup. Second off, obviously the F20C and K20 would have to spin the same direction, or else you wouldn't be able use a RSX tranny on it, Cmon guys its common sense, you put a f20c on a rsx tranny and if it spun the wrong way, then you would have 1 forward gear, and six reverse gears! Just think about it, it all make sense. Its like trying to but a k20 to a b-series tranny, just wouldn't work, the motors spin opposite directions. thats my 2 cents

you sir have no clue what you are talking about....please RE-READ my post directly above yours...

the motors spin in opposite directions - hence the need for the prototyperacing custom ($10,000) bell housing

So does this mean that the S2000 6-speed RWD tranny could bolt-up to a K20 style motor?

no!!!!!! - did you read the whole thread

but anything is possible with enough money...do you want to spend over $10,000 on a custom bell housing....

please stop this thread - seriously

Well, the only thing that the prototype racing bell housing does, is to make the K20 tranny bolt up to the F20C block. Both engines spin in the same direction!! Look At both engines when they are placed in the same vehicle, IE: eg civic chassis, K20 Intake manifold is at front of bay, while exhaust manifold is at rear of bay, which makes sense that and engine rotates through as follows Intake, Compression, Power, Exhaust! F20C: Intake manifold is facing towards the front of bay, while the exhaust manifold exits through the rear of the bay, same thing, Intake, Compression, Power, Exhaust! Hence it rotates the same way as the K20!! If any one can comprehend what i just said then you would understand that both engines roatate the same way,, the prototype racing bellhousing does nothing to change the direction that the motor/transmission spins!!

JDM1civic

Here is what i am trying to say, and i will post pics for proof. Is If you take a b-seriees, k-series, and f-series, and place all the engines with the cam gears facing toward you, all the engines spin the same way! It is said different by honda, because of the way the engines sit in the chassis, but if you put them all side by side, they all spin the same way!!

Time for the proof!






Thanks for looking, make all the comments you want, you learn something new every day!

i never thought of it like that, but now i get it, thanks!! JDM1civic!!!

JDM1civic

No problem, im always up for helpin people out. It dosent really help tho when im trying to explain something, and all people do is shoot me down! But oh well, now at least i kno that someone else understands what i was talking about

JDM1civic

And instead of running a custom bell housing, Couldnt someone(quartersport H2B) come up with an adapter plater and flywheel spacer similar to the H2B kit? seems like it would have the same logic behind it

nice - good arguement for them spinning the same directions

I WAS WRONG ABOUT THAT

there is no point to using a f20c or f22c motor over a k20 or k24...there is much more support for the K series engines....F20c ECUs don't have the capability to be tuned to the point that K-series ecu's can...I believe this is due to the "i" in i-Vtec. pretty sure s2k's run timing belts...not chains like the K. cams, intake mani's, etc. are much more abundant for the K sa well

anyways prototyperacing dropped that bell-housing from their project list b/c they where making more power with K-series. I would have thought if a spacer could be used they would have done that instead ---- who knows

anyways so go ahead with a F20c motor/k20a tranny let me know how things work out...

This would be a good mod for S2k owners or this may be of worth to someone who can get their hands on a stripped s2k. If k&gt;F then I would rather have a K.

JDM1civic

Cool, thanks for checking out those pics guys. I didnt mean to come off like *******, but at leat i put pics up to show you what i was talking bout. Anyways, i agree with you 100% that a k will outperform a f20 any day, but just the mere fact that you could swap in a s2000 motor would be amazing

thanks guys this has been really intresting.

that valve cover jus seems so pretty looking on that FWD transaxle

correct me if im wrong but doesnt the motor usually spin in the direction of where you want the differential to go? the way the arrows are drawn on the motor.... looks like the diff would spin in reverse except on the b-series motor....

must be a solid gold bellhousing then. and with a special idler system to reverse rotation too? because last time i checked a bellhousing's purpose was to fasten a gearbox to an engine block while locating the input shaft axially inline with the crankshaft. the gearbox's rotation has nothing to do with it's bellhousing. get your story straight if you're gonna put others down.

Personally id be trying to get a K20 head on a F20c block, giving the s2000 VTC and a hell more midrange.

In regard to the F20C head swap onto the K20 block:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Brian g &raquo;</TD></TR><TR><TD CLASS="quote">The F20C head will probably bolt on, although I've not tried, but the problem is with the cams and cam gears. If you look at the image below you will see that the cam chain goes over a seperate sprocket rather than the cam gears as it does on the K-motor. If you look at the sprocket (7) you'll see that it drives a helical gear (11), the gear in turn drives the cam gears. That means the cams rotate opposite to the direction of the crankshaft.</TD></TR></TABLE>

Read what was said about the S2000 cams and how they spin opposite of the internal components. Pretty interesting. F20C + H22 seems pretty do'able if that is the case.

honda motors spin as if you had a tire directly comming off of the crank it would pull the car forward. so the B-series and D-series motors spin counterclockwise when facing the crank shaft pulley. the v6, and K-series spin clockwise because the timing side is on the oposite side of the engine compartment. so those pictures are wronge. i don't know about the S2000.

this is interesting also id like to ad i saw in an older honda tuning they put s2k retainers and springs in a k motor to help it rev higher i still have that issue 2
