I was just wondering if a 13B-REW (twin-turboed version of the rx7 engine) would fit with all the superflu (intercooler, intake...) in a NB Miata which is the 1999-2002 model. Me and my friend were just wondering ; ). Thanks in advance.

The motor will fit...but you will have to do some modifying.
The firewall for one will have to be adapted for the larger motor as well as work on the core support/header panel.
Afterwards, once you get the fit you will have to make custom engine mounts and possibly subframe.
Im currently cramming a 20b into a MX3 after a drive swap (which is about the same size as a miata minus the hatch and it being fwd)

The REW wont fit in this car. The Turbo II motor from the 1986-1991 turbo RX7 will fit but a tight squeez it is. Your best bet is put a N/A version of the REW in their with a nice Full bridge port, And many suporting mods and I promis you will make more power over a stock REW and the motor wont be as touchy if it was still a TT. granted you prolly wont make no were over 400 hp but in a miata with anything close to that power will be extremely fast

I believe it would! The engines are sooo small, I can easily carry my short block around! Custom engine mounts and drive line, anythings possible! Change the intercooler to a front mount so the hood can close and might need to modify the engine bay, maybe move the firewall back some? Engine mounts will be the hardest part, only two on the 13B block, trans is the other mount point.

Yes. This swap has been done in Japan many times. But It will be expensive, I would suggest just hitting up flyinmiata.com for all the stuff you need to make your miata fast as is. But if you want to spend the money visit mazsport.net. They will sell you a conversion kit for around $4000, then you have to buy the engine, about $2100 at jspecauto.com. And if you put $6100 in your existing miata via flyinmiata.com, I promise it will be super fast!!

Likely, the transmissions are similar / related in case design and the rotary is certainly small enough to fit. You may have a tight squeeze to fit the turbos but modification is a must to fit the whole assembly. An earlier rx7 may work better.

Too big engine. Sorry, Miatas can't have turbo engines. It's a very small car for it.
