CRX7

You couldn't find anything b/c it just doesn't make sense. Do some more research on the cars that most people do engine swaps on. They're usually engines with little aftermarket support, little potential for power, or reliability issues. F20C in the S2k fits into none of the above categories.

Turbocharge or Supercharge and S2k and you have a wicked beast of a machine. No reason to swap it out.

Sorry for the flames, I know you were just curious here's your answer.

What about the K series motors. I know they spin differently but the K and F series motors are very similar in dimensions and weight. The K gets the advantage of I vtec and a friendly ECU.

Well if you can put a ls1/ls6 into a 3rd gen rx-7 and lose a little weight I figure it wouldn't destroy the precious balance of the S2000's chassis!!

That is a reliable way to get 450+RWHP on pump gas out of an RX-7 or S2000. A nice exhaust, high-flow cat, headers, intake, and some cam work...wa-la!!

Putting the 3rd gen rx-7 motor in with the TT would be silly. It is not a light power plant for the HP it creates at all. An Ls-6 would be a great motor if it would fit. The weight to HP ratio of the LS6 is about the same as the F20C, but with way more potential.

If you want a rotary powered S2000 a single turbo 20b would be a nice choice if you are, or know, a good rotor head. We have a couple of awesome rotary shops here in portland.

To me staying with a honda motor wouldn't make any sense. Why go to all that work when honda doesn't make motors that can produce gobs of HP cheaply and easily? If this is going to be a project for the sake of a project go with something different to make a monster. And don't listen to all of the "you will ruin the car" ..."my precioussss" talk going on here. It's just a car, have fun. It could be a cool project.

Rotary engines are very light and small. That's the beauty of them.
The LS6 has a much better HP/weight ratio than the F20C (From what I've been reading).

I would really look into the Wankel, or maybe even a Supra TT engine.

I think it wouldnt be very sensible. THe Z06 is barely 3100lbs. The honda is 28-2900. What about all the changes needed to the drivetrain to handle the output? Not to mention fabrication......I think you would end up with something close to Z06 speed. And a LOT of problems.

i heard once about puttng the honda aspire engine in

dundonr

lets see.. LS6 stroked out to 427 Cubes with Twin Turbo (725 hp), feeding a rear mounted Z06 tranny and rearend.. it would take ALOT of doing, but you would have ONE HELL of a car when done..

I agree. The reason it works so well in the 3rd gen Rx-7 is because that damn rotary with the TT's weighs so damn much. It weighs about 50lbs more then the LS6 and takes up more room!!

The F20C with tranny is a good 180lbs less then the LS6 with tranny. It just goes to show how much lighter the S2000 would be as a coupe. If you put the F20C into the Rx-7 it would lose over 200lbs!!

The S2000 is about 2810lbs or so...depending on who you ask. Once you put the LS6 and tranny and new diff you would be looking at around 3000lbs. It would be a little lighter then the Z06, but not worth the trouble...that is unless you are just doing it for fun. It would be a fun project.
