The ideal Naturally Aspirated Rotary!

[aaronoverholser]

I would like to stay EFI, I would much rather adjust the system with a computer or programmer than to have to be fiddling with jets all the time. Which EFI system is best, a custom intake and a standalone or just keep the stock system?

I am wanting to know what type of engine I should look to buy and what components to put on it. Should I find a wrecked RX8 and take the renesis or get a TII 4port motor and port it or get a 6 port like I have and port it? Or should I leave the 6 port as is and just refresh it?

All of the standalone EFI units do about the same thing, so just choose one that has local support. You don't want to rely on a long distance phone call to Australia every time you need help, and it is much better to have hands-on help available. The optimal intake would be an aftermarket "Weber IDA" manifold with an aftermarket 2-barrel butterfly-type throttle body. Examples:

That is a debate that will go on long past the time that we all die of old age.

Turbocharging is good for a street rotary because you can gain horsepower and torque without gaining excessive noise. The downside is that you will want to upgrade the drivetrain to TII specs in order to handle that extra torque, and the engine turbo upgrade isn't all that cheap or easy unless you use mostly stock TII parts, although that is also an option. I am not sure if there are still cheap J-Spec TII engines available from Japan after the recent disaster.
