Default S1 and S2 lower intake differences/similarities

I'm wondering if anyone knows if the S1 and S2 lower intake manifold is the same??? or is it completely different so that us Series 1 guys could never do a simple swap of the M62 for an M90 (or M112 )

I'm asking because i would like to get a higher flowing intake system without just getting a smaller pulley because i want to avoid the excessive heat production.

Matt

they are really different because of thier intake port configuration and the snouts on the m90 and m62 are diferent lengths too.
I'm sure an an adaptor plate could be made but would be big $.

I can show you a pic of my LIM, but I dont have a pic of an S2 LIM to show so it would be worthless...but yes VERY different designs!
