But losing air con and cruise and... It stops being a comfortable capable car.
At that point I would probably gut the interior and make it a hard core machine.. And is it the best option for that?
Also- rotary resurrection will do a complete rebuild including pulling the engine and reinstalling it for like three grand.
If you rebuild before the engine has a part failure, there probably won't be any added part costs over what is listed on Kevin's site.
I haven't talked to Kevin in a long time, but he has an excellent reputation.
Might want to look into the smog laws in your area. If your city requires smog checks, it's going to be more difficult to get the car smog legal. Most smog check states require the engine you're swapping in to be newer than the chassis, and from the same class of vehicles (car-->car, truck-->truck), meaning you can't grab an LS engine out of a Suburban or pickup to put in the RX8, as the trucks will have different smog standards.
Of course, if you have no smog testing in your area, the sky's the limit!
They're not the 'perfect roller' in a northern climate due to rust already taking its toll on bodies, particularly on the corner panels by the wheel wells. I'm sure one with an already-blown engine is pretty cheap, but so are many cars (want a 911 with a blown engine for $9,500?).
You would never think with those doors it would be so stuff.
And a no sunroof car (like mine) has tall guy with helmet room.
I would much rather see them cut up for track or engine swap use than crushed.
An LS would be nice and probably fit fairly easily.
RX-8's are pretty cheap in the UK, almost dirt cheap if you find one with a wrecked engine, so the subject of engine swaps comes up fairly often on the UK owner's club forums. So, it's a fairly well discussed subject there.
Swapping a different engine in to the '8 has several fundamental issues to overcome:
- Almost any straight-6 is a no-go, as they're too long and present problems just trying to fit the damn thing under the hood. Either hood clearance issues or steering-rack issues (rack is behind the axle line, so occupies space the engine wants to take up).
- Conversely, anything too wide is a no-go either. This counts out most V6s and DOHC V8s. The space available between the shock towers is fairly narrow.
- Compromises ground clearance. Because the rotary engine is small, it sits quite low, and thus the gearbox sits low too. On some engines, in order to mate the flywheel to the 'box, the engine needs to sit lower than the rotary would, which means the sump hangs out the bottom of the car.
- If the stock dash is to be retained, this requires some effort electronics-wise. Because everything bar the fuel gauge on the instrument cluster is fed over CAN bus by the PCM, you can't just hook up analogue senders. You need an interface. (I've never actually seen documented any explanation of how anyone's done this, so maybe there are a lot of hacked-up clusters out there.)
- Usually compromises the weight balance. Start hanging engines out over the front axle or using anything with an iron block plus turbos and the car is now front-heavy and the suspension needs to be re-engineered accordingly.
From what I've seen, an LSx V8 swap is the best thing you can do. Actually fits (short and not too wide because of push-rod design), doesn't screw the balance (weighs not much more), and there is already a wealth of knowledge out there from similar efforts with RX-7s.

The Esmeril Racing turbo kits seem to be the best available (for anything close to the price).
My concern is the transmission- as they can be a bit fragile if abused even on stock RX8s.
But then again, used ones are fairly easy to find for not that much coin.
You could even swap to the FD's 5 speed unit, I guess.
If you want a good engine swap car- the 2rd gen "FC" Rx7 is a great used car to build up value (better than 240 imo).
Find a solid one with a bad engine for dirt cheap- at least I assume they can be found that way.
They are starting to get rare.
But the FC chassis and even rear end can handle a V8 transplant, and there are kits available.
ChrisV on here built a very nice one.
It's the blue and white one at the bottom of this page.
