So the jy by my house has a few SeriesI supercharged motors, if i get that and pull the whole engine trans, could I just throw a gen V blower on it or are there too many differences and weak points to do that with?

if they are Series 1 motors then no a M90 will not work. you need a series 2 or 3 for the m90 to work

ok, well I guess ill have to find a series 2 or 3. Thank you.

besides it would be less effort with a S2 than an S1 sense you have an S2 already lol

Well I was thinking about a whole drop in rather a top swap just beacue of the whole bottom end thing.

well still why would you put AN s1 in

I didnt know how much differences there were between the series, I thought I could grab a sc s1 and throw a m90 on it.

Very different. The S1 has a M62, the S2 has a M90, different foot print.
