The EPIC is SERIOUSLY strong... That MT2 would be badass... I have one right now in a GT, and it is hell on the MIP clutch... go see pix:
http://www.rcuniverse.com/forum/fb.asp?m=2145552 You can run a real clutch with your MT2 though, so it won't be an issue. I ran the EPIC briefly in another ST with a 4-shoe setup, but a 3 shoe will be fine. I have heard people say that it is overrated HP wise, but I went from an engine rated at about half up to it, and it is easily twice as strong as the former. I get mad wheelies on pavement...
