13bt > renesis and would be probably an easier swap
Isn't 13bt a turbo? If I'm going to fumble with turbo I'm going to do it right, 20b or 26b (I hear theres a place that makes a kit so you can build your own) Really all I'm looking to do is make the Fiero better around the curves, improve the weight ratio and do a swap that nobody else has done. I think the Renesis will leave more engine bay room, and stay cooler, which will make the car more reliable. I think I'll be able to spank a lot of cars out there with it. The car weighs about 2700 pounds right now, I think the rotary is probably 3/4's the weight of the gm 2.8, maybe even less so with the 238 hp the Renesis has I should be able to do fine. I figure I'll probably get a little more power out of the motor than I do in my RX8 since the intake will be better, the exhaust will probably be better to. (By better I mean more free flowing) Can you point me towards some technical write up that shows difference between the two?
I'm looking into injecting hydrogen into the intake, so if I get that figured out I'll probably get a little more power from that too. Don't think about this too deep, I'll post info on that in a different area when I have a system together so everyone can benefit. I'll post dyno results too.

how much can you pick a renesis up for?
About 2500, I don't know if that includes the injectors, etc...
I'll be looking for smashed up RX8's for the electronics though.

+1 for Crass's suggestion. A mildly modded 13BT is actually a pretty low maintenance engine. And if you do want to run N/A for simplicity sake, then run a 13B instead of the Renesis. There's a lot involved with the Renesis that isn't there on a normal 13B. Just my .02 though.

a bridgeported n/a is going to spank a renesis for the same price maybe less or a 13bt motorset again about the same price as the renesis.... remember the renesis is rated lower than what you mentioned and that is not whp.

I have a 1987 Fiero GT I am getting ready to do an engine swap on. I'm looking at putting a rotary of some kind in there, maybe a 20b or a 13b-renesis. I'm leaning towards the 13b renesis because two cars with renesis is better than one (I have a RX8). I need some help though. I found a place that will make an adapter plate for the engine/tranny, but before I get all excited what I really need to know is if the rotation of the driveshaft is correct. Anybody know? Also, anybody know of a good place to get an rx8 computer so I can run the motor with fuel injection? If this project seems too hard I'll do a gm 3800 series 2, but the coolness factor won't be as high.
The rotary rotates clockwise when looking from the front.
I used a steel 1/4" plate to adapt a Chevy S-10 bell housing to a 12A. Should work fine on a Pontiac. I can explain the process if you want to try that.

Re: Rotary in Fiero?
I just found this thread, I am planning a Renesis/Fiero swap as well. I am having trouble with finding a transaxle that will work, I'm looking for a 6 speed manual.
