u want to keep it n/a??.....supercharging a car is a form of forced induction also....s/c is belt driven as opposed to turbos which are done by exhaust (turbine) gasses.....i dont think i've ever heard of a s/c kit for a supra but i could be wrong......

There is NOT a supercharger available for the N/A 7M-GE motor. There are pictures floating around the net and cardomain.com of a 7M-GZE but it is the only one of it's type anyone has ever seen.

On top of that, Supercharging (as it was said above) is a form of forced induction. Slapping a S/C onto an N/A motor, makes it forced induction.

Lastly, Supercharging is inferior to turbocharging. Why? Linear boost. Superchargers (for the most part) will only reach maximum boost at redline, therefore the percentage of boost is found by the percentage of current RPM's from redline. Boost levels are more expensive, and more difficult to attain (changing pulley's = Pain) where as you can install a boost controller on a turbocharged vehicle and change it on a whim.

If you seriously are asking, expect to be flamed off the board on SupraForums.com

serious. It's spelled "serious".

Well then, there's the Jeeves $0.02 on S/C's on the 7M.

Hah, that link above is Peewee's site. He's an Australian guy on the Cress forums who got a 1UZ-FE up and running in an MX73 Cressida :)

Changing pulleys aren't so much of a pain. While it takes more effort than just cranking up boost via a controller, you can do pulleys on a whim in < 15 minutes, assuming you've got relatively cheap adapters. I know this because I hang out at BonnevilleClub.com; SSEi Bonnevilles have 3800 SC powered cars. Easy power is attainable with pulleys. But intake/exhaust mods beforehand are a must, and you need new rockers if you're going further.

SC isn't all as bad as some see it... lagless... but I myself can't really say I prefer one over the other.

Supercharging an NA MK3 would be a pretty expensive project, but it is entirely possible, especially if you had really deep pockets or had good fabrication skills and had friends in a machine shop. Using a Roots type blower would be very expensive and difficult, as it would require a completely custom intake manifold among other things. A centrifugal would be a lot more practical, but mounting it would either involve A/C deletion or some custom trickery with the power steering. Engine management would be a huge PITA, although you might be able to work it with the crappy flapper door AFM and stock ECU if you used larger injectors and an AFC, along with a rising rate FPR, as long as you used a thicker metal headgasket to drop the compression and backed off some ignition timing.
Basically its a project I'd not attempt unless you had at least $4-5k to burn, and I'd not hope for more than around 300hp on the stock GE block With the stock ECU. If you wanted to go balls-out and get forged pistons and a Haltech or something you could theoretically make 450+ with good intercooling and everything else covered, but it would be much more expensive than building a 7M-GTE to those power levels.

Good ol' KenneBell. 14psi across the board :D No pulley change needed.

Sadly they don't yet make one for the Supra due to lack of interest.

In my opinion if you could supercharge your car, then go ahead because if it does work I believe at the end the turbo still going to be as fast as the supercharge.
