There is a stroker version of the 4.0L motor too (makes a 4.6L). 260Hp @5200 rpm - 295 ft-lbs @ 4000 rpm. Its a bit pricey. Info on quadratec.com website. Looked at it for a '97 Wrangler.
May want to check out Chevy's inline 5 cyl from the Colorado/Canyon line (H3 also). I've seen some interest for Toyota truck swap (getting rid of the 3.0L V6). Like 240 Hp and lighter weight than the 3.0L, I believe they are an all aluminium motor.
I dont think those are same as mine (the Hayashi's are alot nicer).
hese have the Itall Racing cast into one of the spokes - If I can find my digital camera, I'll snap another pic. Thanks for the link, I'll keep an eye on it.
I'd like to find 3 more of them. When I sold the Fairlady, I was supposed to get my wheels back (but never did - yet). I have the 5th one that was the spare.
