Supercharger Question
Sorry, I tried to do a search, but for some reason my PC at work won't load the search page!! (Dern PC)
Anyways, are there any superchargers out there that will just strap on to a 13b that's fuel injected?? Or if I want to go the SC route, will I have to switch to a carb setup??
Thanks,
Jeff

Try Paxton SC
or Vortec.
Dont exceed 4-5lbs of boost, and even then a stock engine could blow.
If you are lacking power, and your car is old, then set it back to stock.
I mean "do the hard thing" first and check your 6ports, and get all parts back to original working order.
Check your compression.
9 times out of 10, if I secretly replaced a old worn rotary with a new fresh rebuild, then the owner could almost think I supercharged it.
These non-turbos are strong, but you could also check out the 180HP engine at:

Its a BLAST!

Gimpdiggity,
Having a supercharged Turbo II or NA rx7 is definitly sweet. Big props to low end torque and instant boost - makes a sweet ride.
Some more pages to check out:

Of course as with any boosted car you want to plan out fuel delivery and air/fuel mixture. Slapping a supercharger on with the OEM fuel maps & computer can be very tricky. I'm planning something similar with a convertible and I want to research a) the different types of superchargers (intercooled vs air/air is only 1 factor) b) how much boost I want to push c) preventing "overspin" of the supercharger as these cars do have a 7K or 8K rmp readline and d) which aftermarket ecu is best to use.
I think the end result however will be great

RETed,
I need to ride in a supercharged TII and/or NA.
My convertible project is mixing the TII drivetrain/engine with a supercharger. I like how road runner describes the setup on his NA. Now imagine having the TII exhaust & intake combined with the supercharger instead:

I love it!!! A normally aspirated rotary builds it's horsepower when it revs, but with the supercharger its a totally different beast. The increase in low end torque is great, and the mid-range power is a rush. Throttle response is also improved, its much crisper now. When the six-ports open up, you can actually feel a rush of power. Got some jerk tailgating you? No problem. Drop it down a gear, floor it, and you... are... GONE!!!
The supercharger has made my 30 mile commute to work much more enjoyable, although I've got to be careful when stuck in bumper-to-bumper traffic. When the clutch engages, she just wants to go. And of course, I always get my choice of lanes pulling out of tollbooths. Hahahahahaha!!!! Last but not least, I was worried about gas mileage. But if I keep my right foot out of it, I can still get around 22mpg. By the way, I passed emissions testing way back in May.

I've regularly come across Turbo II's for $2k or less.  The Paxton is going to cost you over $3k easily minus labor.  There is a limit on how much boost an SC can do to an NA engine - under 300hp.  Sure the SC is going to get your more bottom end power, but it's really moot if you've ever been in a mildly modifed Turbo II.
I really can't see spending the money on an SC, when a lot of the (NA) parts are on the verge of breaking.  I know you've mentioned your mix of NA and turbo parts, but the most important component is the engine - unless you're starting out with a Turbo II engine, there's a limitation on boost.
Now, if you're stuffing a Turbo II drivetrain and engine into an NA, I'll call you crazy.

yep - the mildly modifed Turbo II is my weekender, but I'd like to have a supercharged boosted daily that has better low end torque for that stop'n'go traffic and some good pickup without boost creep. - So why not a turbo II convertible (minus the turbo) that's supercharged
It's different - and cool
Hard part is finding a smashed/burnt TII (don't want to strip a good one). Where the @#$*#( do junk yards & parts places find there's?
Actually - I think paxton has either 6.5 or 15 PSI superchargers according to their site. It's all in the pully gearing apparently.
