Hey i may have something for you
I have made a supercharger setup for my convertible and was pushing up to13 lbs with a Eaton M62 but i want to get my car back to stock since my wife is now using it alot....
She does not like the sound it makes and she does not want the extra power.
Let me say that it is alot of fun but i have to take it out....
If someone is interested i will be selling it as a kit with the brackets and all to mount it on your e30...
