Brian Kraus ursnoozin@msn.com has and sells a kit to put a rotary in a Spridget. He has a really nice yellow one that was the subject of a Grassroots Motorsports article a while back.

I have a Mazda 13B and truck tranny for sale that has been race prepped by Bret DePedro for sale if you are interested. He rates it at 250 HP! DePedro prepped Brian's rotary. He is well-regarded among Mazdarotaryphiles.

I dunno, Doc, Brian's car looks like it's still in one piece! Of course, I don't know if the HP rating is 250. And, Brian has done lots and lots of strengthening!

Mostly joking there, John. But running that kind of power thru an old Spridget frame without doing some careful engineering before hand would likely do some "quirky" things. Especially if it were a torque monster as well. Not so much a concern with the rotary as with something like a banshee'd up Rover V8.

A friend and I DID that to a Frogeye he had back in the mid-70's. Used a shortened diff from some GM-or-other (can't remember). Angle iron for frame rail reenforcement. Thing gave new meaning to the term "throttle steer"! Too much of a handfull. He sold it and got himself a real car: '67 E-type.

yeah the torque band is real low on it...maybe about 3500 when the horse power is up at like 6500 or 7000...
