If you try to attach the s2000 gearbox with a k20 only 2 holes will match up. Prototyperacing developed a one-off custom bell-housing for a f20c to bolt up to a K-series tranny...cost was kind of high...

ok, I am sorry.. I was confused..

Prototype racing made a plate to attach a kseries tranny to a s2000 motor.. so the opposite would be possible as well

So its a different block altogether then k20 to a s2000 engine?
Yes.. If the Blocks were the same, there would be no need for an adapter plate for the link posted above.

The two engines are very similiar, but different.

after seeing F20 gearbox & K20 gearbox side by side this summer,i think you can't put a F20 gearbox on a k20 engine because the mainshaft is around 1.5" shorter so you can't engage it on the clutch...

it's my mind:(

I'm probably missing something, but why would you want a F series in a fwd platform?
The prototype racing kit is for an Elise.
In a FWD the F20C would make for a killer turbo motor for dragracing, that is about it as far as I can tell.

Makes sense, thanks.

It'd be interesting to see K series in rwd platforms.
I run a K20A2 with a Toyota Corolla 5 speed RWD transmission in my LowCost 7 autocross car. I used the front half of the DC5 6 speed case, and a 3/8" flat aluminum plate a I machined to match the holes in the DC5 case and the Toyota transmission. It works fine. The car won this years National SCCA SOLO D Modified Championship.

That's pretty nifty, you should post some pictures. You use an old 4age tranny? How does that tranny hold up? What else was fabricated to make that work in that car?

I don't have any seperate pictutres, but when I dismantle the car for the Winter refresh I'll shoot some pictures of the bellhousing/adapter. It quite simple, the stripped front 1/2 of the transmission case, a flat 3/8" plate, and the proper holes drilled in the plate. (I had to make the pilot bearing myself. The Toyota input shaft is smaller than the Honda bearing.)
The first time I built the adapter I welded the parts together and it warped, causing a misalignment of the transmission input shaft, and consequently wearng out the syncro rings and causing the transmission to jumop out of gear. The new, bolted together arrangement has cause ZERO problems. The 4AGE transmission are pretty rugged. Of course the car weighs only 1850 with driver, in E trim, and only 1440, in D Mod trim.

Motor is 12.5:1, IPS K2, KPRO, Mahle pistons, Scat rods,header by Del, dry sump, 9500RPM redline. Rear end is 7.95:1. We leave the start line in 4th gear and don't shift.

Oh yeah ?

Only good for a turbo setup?
