How much performance out of N/A
I am new to the whole rotary world, I am used to being seated behind a huge V8 engine of a Corvette. I got the 1990 Rx-7 as a project car, it is non-turbo. I got it at a great price and thought that I couldn't lose out on it with the price I payed for it. My question is....
How far can this engine go non-turbo?
It runs good, just a little afterburn is about the only problem.
If I have to I will put either a turbo on it or swap the engine out.
Any help would be great, thanks...

To be honest, there's not tonnes you can do to the NA to make great gobs of power and still be streetable (besides installing a turbo). A bridgeport and nitrous can put a good 250 down to the wheels and still be reliable, but if you want to make more, you're looking at peripheral porting and other extremes.

Aaron you've got a good point. However being an N/A maniac i'm also a GO for getting more power.
I'll make this short since it's been covered in Previous threads.
Basic mods, Intake Exhaust (FULL) iE: Header/mid/catback of highquality. This will yeild some noticeable powerincrease. Throttle body mod, emissions removal (yes i know. removing emissions doesnt help HP but it does make engine bay relitivly easier to work on)
After these basic mods you could get a light flywheel. maybe even get some Nitrous.
Than comes the bigstuff. Porting, rebuilding (get that motor running to 110% compression and add a nice Large/mild street port you'll be all set.
One of the largest drawbacks of the stock ECU system is the AFM. once you've got a street port and header and intake ect.. all that Air is trying to go thru a small/cheap/ now ineffective silver box with a flapper door. This will be the time to upgrade to a standalone EMS Haltech/wolf/i recommend Microtech (only cause we sell them) With all those mods and a standalone ANY ENGINE would come alive.

P.S Microtech/BP 13b 4port coming soon...

Ive done the whole T2 thing with the fuel computer but I still love the feel of the n/a and I would love to keep driftign more and would rather do that in a n/a.. heres what I plan..
1990 block / huge street port / twm intake manafold / microtech / aluminum flywheel / street strip clutch.. with full suspension that would make a very fast n/a

BCTY your are very correct. with a large port, proper fuel system and FULL exhaust with some sort of Cold air induction (plumbing to front of car?) and Standalong EMS you could be pushing around 220-230hp at the wheels. Could be more could be less that's a good estimate That Aint badd.. now is it?

Turbo kit for N/A
Dave Gibson at fc3s.org is in the development stages of a turbo kit for us N/A guys. I personally perfer a supercharger but figured I'd spread the word for him. It will be awesome when he's through. Go Here and then click on "new products" and you'll see it under there.

hey if i get another n/a i would love to get a supercharger for it.. but that is one of those n/a myths that seem to never happen and someone is always trying something to get it to work ( air pump ) it would be awesome to have one and ill buy one if it hits the shelfs.. love to try the different feel over a modded turbo and a highly modded n/a..

Stock intake manifold system, thats about where you're going to top out a 6 port block. The AFM is not as restrcitive as people wish it was.

13B not torquey enough? Drive 10A or 12A cars, you will feel 13B is so torquey Anyway, you always gotta stay on high rpms if you want to go faster on NA, but you don't feel torque much...
