I am not all too familar with the M90 off of the ThunderChicken, so I cant say how that setup will work, I know that the nose-cones are the exact same, but I am very interested in seeing how it goes and what the end result is. I will add this much, depending on how much boost you are looking to run, you might want to look into a COG BELT system if you plan on getting around the 3.0 pulley! I know that the 3.8 has quite a bit more power to spin the belt without loss in overall power, so the 2.0 might not have this issue, but even with a 6rib belt system and larger tensioner pulley, we started having belt slip issues when we went down to the 3.0 pulley because it was trying to turn that thing so fast on that small pulley that the belt just couldnt grip. We couldnt even finish dyno tuning it because we couldnt get the boost to stay consistant, so we saved for the Eaton COG system which was stupidly priced, but now that we have no belt issues, we found that we could go down to the 2.8 pulley and its now tuned and sounds CRAZY! Keep us posted and thank you for what you do over there!
