The ideal Naturally Aspirated Rotary!

[Max777]

What's the prospect? If you've done this before, my opinion would be different,

aka: 13b-rew converted to N/A, exessive intake manifold, haltech ems. However this will make you run into some challeges like mounting of the engine and etc.

The reason for this is that the rew has some updated stuff, like the TPS, the coil packs are "neat" unlike the FC, it doesnt have the stupid ugly CAS, it's got multi-rib belts instead of the annoying v belts, and it's just a nicer engine all together.

The biggest reason however is that the REW is a 4 port and has bigger intake runners stock than an S5 TII, so you could do quite a nice steet port and be done.

another option would be to do what was suggested before: Individual throttle bodies and a standalone. This keeps your stock engine but deletes a LOT of the finicky stuff that pisses me off to all hell about the n/a FC setup.

Why is there such a strong bias against turbochargers btw? with these engines, it's the best gang bang for the buck.
