dont tubrocharge it, supercharge, it think about it, when you use a tubro you just dumping hot exhaust back in the motor to get hotter!!!!!!! know wonder the heads crack??? check this out www.rotrex.com
ej2.2 wieghts in at 300lbs ready to run at 130hp
ea81 80hp ready to run weight 175lbs
2.2 = 50hp more = 125lbs more in weight if it was me i'd skip 2.2 and go right to 2.5 weight in a 315lbs for the 15lbs in weight diff you get 35 more hps.
if weighty matters ea81
if it don't 2.5
