I thought I’d better have something interesting for you guys to kick off the new year, so let’s get the ball rolling. It’s another one of those builds that I’ve had my eye on for a while, but it wasn’t until it was emailed to me by Grant that it powered itself back into my line of sight. What we’re looking at here is a 2nd gen Honda CRX with an S2000-sourced F20C stuffed in the engine bay with a turbo hanging off the side, to be powering the rear wheels in the not too distant future.
Not enough RWD-converted Honda action for you? Then check out the mid-engined RWD DC2 Integra, and the AWD twin-engined Del Sol.
Or, if F20C’s are more your thing, there’s the TA22 Celica, ’66 Sunbeam Minx, and Opel Kadett, all powered by Hondas 92.1kw per liter engine.
UPDATE SEP-2014: This car is now complete! I’m not sure if the build thread has been updated, but MotoIQ have done a 9-page spotlight on this very car. To check it out, click here.

I love it, but I’ve always found turbo f20c’s to be a little silly. The f20c’s claim to fame (volumetric efficiency) is largely null and void in a turbo configuration, and the engine needs a rebuild to take a tame amount of forced air.
Still, it’s a CRX (my first love) and it’s RWD (my second love) and it’s an extremely high-quality build (my soul-mate). I can’t wait ’till it’s on the street.
AS much good work went into this there is numerous flaws. One being they never reinforced chassis before they cut out the part of the floor and bulkhead. Then they added in WAY to much steel tubing for the transmission tunnel that adds weight and is not necessary. Hopefully they do the rear end correctly or they will have a heavy non-straight framed car.
if you read through the build thread and looked at all the pics, you would have noticed that the tunnel was cut only one half at a time to retain rigidity during the fab process. also, the car was completely stripped and not on the ground, it is on a lift to prevent any movement in the unibody during the whole process. the rear end was actually completed before the tunnel was started. the reason for so much added tube in the tunnel is to compensate for the strength removed from the floor pan because the tunnel is now higher than it was originally. believe me, safety is my first concern on the finished product as i intend to take my kids for rides in this on a regular basis once it is complete. estimated weight of the car after the conversion should be around 2300-2400 lbs. the stock weight of the car is 2100 lbs. my biggest concern with this swap is bump steer with having had to lower the steering rack so much.
actually, because the internals on the f20’s are forged, they handle boost nicely. they have made as much as 700hp bone stock, even the intake manifold and tb! i plan on running 1 bar on my gt35r with stock internals. with some good tuning, that should net me around 500whp on pump gas.
This is how all cars should be built. Small car + RWD = tons of fun. And don’t flame me if I’m wrong, but wouldn’t building a sub-frame have done better at strengthening the bottom of the car then overbuilding the tunnel. Just saying, it’s probably what I would have done. But I’ve never taken on a project of this magnitude, so I wouldn’t know.
Thank you for sharing your nice project with us it really smart and professional, I have gen 1 CRX 84 model and planing to apply the same way like your project but need you kind help and guides in this if possible
My car is complete mugen kit and I like the idea to have it powered by f20c, I have also the engine and the gear
Appreciate your kind guide and help
@Jesse…. WTF are you talking about? The stock F20/22c is good for 800whp STOCK BLOCK when turbo. People are into the 700hp range without even lowering stock compression much less rebuilding. I’ve got a 800whp ready F22c so I speak from experience. Please don’t spread around info like you are that is completely incorrect. s2ki.com forced induction section should prove this.
Tame amount of boost? 800whp on a stock block not enough for you?
how did you convert the rack and pignon and the front suspension and the read what part did you nead to convertit
Kudos, I appreciate it!
Great info for beginners like me!!Thanks a lot!!
weirtech << I HAVE MY 91 SI WITH A WIDE BODY KIT ON I WOULD LIKE TO DO THIS TO WOULD YOU BE WILLING TO DO IT FOR ME IF I PAID YOU. I CAN BRING EVERYTHING TO YOU AND LEAVE IT I AM NOT TIME SENSITIVE IN ANY WAY. PLEASE CONTACYT ME UNTOUCHABLECC@YAHOO.COM THANK YOU FOR THE THREAD!!!
