Blue Steel Performance Rotrex Supercharger

[Piluso1]

They have in the site a supercharger for the 325i M20 engine and was considering using it on my 325e, any thoughts or ideas are welcome and I want to know what would be involved in installing one....

I was considering a supercharger but decided against it as my 325i had 100K miles when I got it. I think an M50 engine swap is a more economical idea with similar results. I think these beemers tend to be better off with normal aspiration. If I had a brand new E30 with less than 50K miles I would probably go with the supercharger.

Yes, I would imagine you would have to get many forged parts for your engine to get a SC to work on a m20. Its much more beneficial to do a m50 swap. They have 240bhp and there is an availible SC kit by dinan which does not require you to change an internals as long as you run under 8psi. And it puts you from 240 to 370ish...

thanks...i was considering an m50, but they're hard to come by here , unless they are really beatten up...

what is the m50 motor,what cars did it appear in?

According to my info, the M50 was in the E36 325i, E36 M3(S50?) and E34 525i

m50s are easy to obtain and you can get them for about $4500 with a tranny and all the electronics with about 80k on them, www.roadfly.org
