I have a 91 NA and trying to plan out exactly how far and what i want to go with it. I would like to get a supercharger for it but would like to know how much power i would make with it. At www.camdensuperchargers.com they have a 7 inch and a 9 inch supercharger i would like. I read somewhere that the 7 inch produces about 12 pounds of boost. On a NA, how much power could someone guess that would make and then how much on the 9 inch would someone guess? Thanks

It says there is a 170 hp increase. But i dont think that the na motor will handle that boost. The na motors are high compression, as opposed the the low compression turbo motors designed to handle boost.

why supercharge a rotary, chargers rob hp to make minor hp increases. you would be better off taking the engine out and buying a frount clip of a car and converting to a turbo. it would coast about the same anyways.

Really? I thought it would be cheaper and less work to convert it to supercharger. I saw a kit for like $2100.

Does that kit include new rotors/apex seals that are lower compression? I wouldn't personally supercharge a rotary because it's just another belt to have to drive.

give me more info for converting n/a to turbo II.



explain front clip



Est. Cost?

Front clip is from the front 1/4 panels up, minus the suspension, all the engine components, everything in engine bay. Not sure about costs though Jason. It can be different from supplier and the demand for them at the time.



Cost of swapping, all types of different figures. Figuring the cost of the clip+ an extra 10k to spend. Just give yourself a limit.



What do I know though, never done one before.

I don't think you'd see what you want to see with a supercharger. I'm no good with all of the mathematics, but there's a lot of reasons why they're on the bigger engines and the turbos on the smaller.

wow. for any conversion besides a 20b for $8k, i would rather purchase another rx-7 turbo...or save a few more thousands and get a FD lol.



I guess im just BSing cuase if i had the money i would spend it all on my 7..

I have thrown the idea around a little bit and considered a camden for my car, being from the school of overkill I went off the deep end on mods for a N/A and I think my engine would hold up fairly well. It's my understanding that the tested config for the EFI set-up is a stock engine with bolt-on supercharger that puts up 176 hp on the dyno, 6-8 psi of boost. NO it still isn't as proficient as a turbo application but the mod costs $3300.00 and adds 35 hp in an S4 application, not to shabby in my opinion.
