Turbo lag is an excuse. A properly sized turbo will give boost from 2000 all the way to redline. When do you ever need power under 2000 except on the highway cruising.

Off boost = better gas milage.

Everyone knows Turbo > SC unless you're a bitch and drive a domestic V8.

Still? I wasn't aware of any companies making S/C kits for E30's.

Nobody does, because they're dumb.

And I don't know what you're talking about 'random power' of turbos.. if you have someone properly match all the parts of a turbo kit up to your power goal you'll have almost an equal power band as a S/C setup.

New turbo technology has simply come a long way to think that turbo system have to be peaky in nature. That and there are too many people that just throw on GT40's.

Modern ball bearing turbo + electronic PWM boost controller + very linear boost and power levels.

Just something to think about.
i agree with you 100%, plus nobody makes SC kits for E30 (from my knowledge) and what is the point of supercharging something that does not have power to begin with

^^^LOL...@ Sam.

we're not trying to be hard asses or anything but to answer your questions there is NOBODY selling a "kit" to supercharge your m20...If you really want to supercharge as bad as you do the next best thing would be an budget m50 Non-Vanos swap, delete A/C (so you keep the same weight up front) and supercharge that since there are off the shelf s/c kits that are for e36s but can be made to fit in an E30.

Or make your own SC setup. Goto the junk yard, find a GM 3800, steal the eaton m40 twin screw sc off it, then start there.

I have an eaton m90 I would go cheap. I was going to mount in where the alternator goes and put the alternator in place of the compressor. I also have a pulley that fits the M20 for it. Custom brackets, intake and charge pipes would have it running, and a supercharger is a good candidate for a BEGI FMU and 21# injectors for fuel management.

The eaton I have needs a new front seal and oil, but you'd do that with any used SC. Rebuild kits are cheap, like $50 or so.

It's true... my friends E30 was a stock SETA before it went turbo. Just with a stand alone and a quick tune (no dyno tune) it would pull away from my Jetta VR6 no problem.

When he was on the stock Motronic I was able to pull on him.

An MK2 VR6 is only slightly faster then my MK3... so meh.

A supercharger would be good for a small bump in power I guess.

Small bump? More than that. You could double the torque of the m20 with a m90 properly tuned. The low end torque boost of a supercharger is far better than most turbos, and they're linear power development makes the motor behave like a much bigger NA motor. With a large supercharger you'd also see serious peak HP numbers, but the overall torque curve is where its at.
