But why are you carbing a previously fuel injected car? That's retarded in my opinion. You're losing the little bit of fuel economy that we rotary owners have and you can't be gaining much if any power.

Cause he felt like it; I'm sure it makes his whole setup a whole lot lighter...

it may be lighter, but ehh.. i guess your plans are to eventually turbo it, in which you wont need expensive computers etc. just tuning the carbs? seems difficult to me. esp when a stock tII would have more hp...

but its cool, esp the empty looking engine bay

Wrong, OEM EFI vs his carb setup; the carb setup will yield more HP.

WRONG.
EFI or carb doesn't matter of horsepower potential.
The engine still will only take X amount of air, and you still need to dial in Y amount of fuel.
There's no rocket science behind it.

If you're going to argue for carbs, do it right.
The shorter, more compact INTAKE MANIFOLD will yield more top end power over the stock EFI intake manifold.
...sure.
Throw on an ITB with fuel injectors, and your carb set-up will not make more power.

If anything, low end power suffers.
Mileage suffers.

Personally, carb conversions are for people who can't figure out the stock EFI...
You make the call on about their intelligence.

Side note, I think I called it that the OP was never going to finish that project in the first place...

You know that's what I meant, specially since there is no carb intake manifold, that will yield less top end than the OEM efi (unless you adapt an old OEM 12A\13B intake manifold to the 2ndg gen)

You missed the part were I said OEM EFI vs his carb setup

Chit, a stand alone on a OEM intake manifold might yield the same peak HP as an aftermarket carb setup.

Whoa, what is there to figure out on the stock EFI? If you want the most HP out of a EFI NA setup, there won't be any STOCK EFI component on the car.

ok how much hp can you get from this?

i want to find a 70s porches 911 and put a rotary in it because Porsche motors are expensive.. really expensive..

and a carbed 13b would probably be easier to setup/get the ball rolling instead of playing with all the EFI equipment.

Also with the racing beat holley kit, it fired right up and idled no problems, it pretty much comes setup to run and they have it tuned for stock motor with the race pipes from what they told me.

After driving an NA rotary, doing a turbo swap, then going big single turbo I can't for the life of me figure out why anyone would ever want to go from turbo to carb...

Good luck though, I hope you hit your goals. If you get what you want out of it and it makes you happy, thats all that matters in the end.
