The 3.8L V6 as I recall, was a poor breathing, heavy, piece of push-rod rubbish. Pulling its M90 blower is a good idea though. I ran that blower on my Probe years ago - then opted for the M62 as a better fit. A custom IM to fit the blower between the valve covers would be good, but I don't know if it'll make hood clearance. An M62 is compact, and on my Probe I simply replaced the AC compressor with it, and all is well -- It seems as if we'd have room for that with the Duratech as well. The Superchicken blower might work as well, though a shortened snout should be necessary. Then again.. I think that this is the wrong forum section to go on about forced induction.
