Ok, at the moment im considering wither dropping a m30b35 into my touring or trying to put together a decent m20b25 supercharged. What i would like is if any people on here who are running said supercharged engine, let me know some feedback/link to there project. My thinking is that i guess having the m20 instead of the m30 means handling should be a little better aswel as the supercharged m2 producing a little more power then the m30.

Cheers guys
