I have an e30 m3 w/ an obdi converted m52 that was intended to be turbo'd but I am now considering the SC route. Has anyone hooked up one of the eaton's off the early 90s GM 3.8L's (pulley on the nose)? I imagine clearance is impossible and a centrifugal is the only option. In any instance, has anyone done a DIY SC job and what did you incorporate or learn you should have?

I'm well aware of the eaton "junk" label associated with this model SC and should go twin screw, etc; none the less this is readily available, easily replaced and opens the door to a fun project without any serious financial sacrifices. -
If it helps, I am currently/temporarily running odbi software for the s50 by bmp w/ the injectors from the 3.0L (so injector pulse rates dont cause a major problem this is only to make it run while I am properly building this thing up to where it needs to be), m50 intake manifold, s50 throttle body, stainless free flow exhaust from headers back, 3.5 HFM (i know, i know, even with cams some say there are no gains, but I essentially was given it so i threw it on w/ everyones favorite, k&n cone filter), and most importantly NO AC OR FAN (electric aux fan, front mounted) which is valuable for this whole operation (can this pulley be used?). If i get an eaton roots s/c can it in fact be driven by ac pulley or utilize the open space? How can i get clearance? and most importantly, where do i start for engine management and MAP sensors?? Any informed help would be appreciatedLast edited by m52 e30; 07-10-2006, 07:59 PM.Comment
