Anything above the measly 115hp of the 2.8 will keep me satisfied! Yes for sure, the AX- 5 will leave in time but I'm assuming that time will come soon! I'm not sure how the clutch will hold to the power increase from the new motor! I'm not sure how the T5 transmission compares to the AX- 5 but if they're anywhere near the same the AX- 5 will be slipping!
