Default Supercharger kit

Is there someplace that I can get a supercharger kit for my 88 325is? I searched the web but couldnt find any, I want the whole kit, hoses, inter-cooler, chip everything.

There used to be two companies making a rotrex kit, but it seems as though they no longer do. Cost was around $4000. so i don't think to many people stepped up for the kits.

DIY will run around a grand. As far as kits none on the market now that i know of. You may want to look into a turbo kit.

Looks like they are gone or site is down at the moment...

I still want to go full out on a supercharger and make a bolt on kit, made out of a new Eaton m62. Yes it will probably be expensive but it will produce a ton of power. Maybe i will go with the rotrex path. Anyone know how much boost they can produce I am looking from 10-15psi? Sorry for the thread jack

I think a most of the rotrex models run out of steam around 12psi
The new m62 works out pretty well on the m20b25 and b27.

If you want to go with high boost check out two m45s on the m20b25.
Try it out with the eaton simulator. says i could be pushing 500hp out of a mild built 2.7l. Now that is sweet. Twin supercharged FTW.


Back on topic

I did a little searching and came up with not one m20 supercharger kit, sounds like this is a open market for a new kit .

Wow lots of dead-ends...

Looks like another dead-end, some of the links are bad
http://www.rosemdesign.com/lowen/pages/supercharger.htm

Another possible source
http://www.g-powertech.com/rotrex/eursett.htm

Might be worth trying to contact to see if they are around.

Lots of those electric ones available

Lowen designs
Is a total bust, the guy was a major ass and ran off with a lot of peoples money.

The second link looks like a good lead i might look into that one.
Thanks

Mel at A b r a h a m s Motorsport sells a kit from Schmiedmann for something like $3000 I think? Maybe closer to $4000 at this point though.

Email him and he'll get you a quote. Great guy to deal with, I'm sure he'd be more than happy to get you supercharged!
