I'm holding off on my rebuild to get more info on this. Sending your FD engine to Pineapple can cost you the same $6-$8k stated above. Although, I don't think it would be that cheap. An important factor is will the PowerFC be available so you don't have to buy the RX8 ECU.
Now the most important questions: 1. Will the overheating problems be gone it you slap a turbo on it. 2. Will the Apex seals have a longer lifespan?
If it works out well, I predict it to be as common as Acura Motors in Honda Civics! Eventually we'll see motor mount kits and all that stuff.

Has anyone got the measurements for this? If so, please post! I assume that since the 8's been out in Japan for a little while, somebody's got to have the numbers. Detailed engineering drawings would be better of course, but I'm not that much of an optimist--I'll settle for the other. But having considered the same thing, I figure we're going to want measurements of the following (at the very least):
1: Locations/distances for all mounting bracket holes, and the bolts on the engine frame holding it in place.
2: Length of the transmission and attatchment placement for that (I'd rather not carve a new hole for the shifter).
3: New length of the driveshaft, from the back of the new tranny to where it meets the old differential.
4: Clearance in the engine bay. Since the 13B-Renesis is smaller overall than the old 13B's, I doubt it will be an issue for RXciting, but for 1st Gens, I don't have a comparison of Renesis vs. 12A size. Let alone if you're thinking of adding any kind of forced induction, since that'll add more volume needed in the bay.
5: Running temperature of the Renesis. It's probably the most important thing. We can cut, order, etc. new mounting hardware. If the Renesis overheats after all that work, we're screwed. Cutting holes (or redirecting cold air) shouldn't be that big an issue, but I'd like to know about it ahead of a blown seal.
6: "Soak" weight of the Renesis. While we're considering making new hardpoints, why not slim them down to jet-fighter tolerances?
Sorry if I'm just stating the obvious. But damn, I'm gonna love this project. Even if it takes 10 years and the 4th gen 7's are out by then, it's gonna be worth it. An RX-7/8 (?) should make the ultimate rotary.

1a. they wont fit either
2. in na form yes, turbo ?
the renisis motor is 5k for just the block (new, there arent rebuilds yet)

just do a 20b. whats the point of having a new renesis when you can have a 20b? i guess it would be a little cool for bragging rights but a 20b would be much more cool.
