Hi Scott, Ron and Q-List: Hmmm... Does the 2.5L have piston oil squirters? If so, how hard would bolting on a 20V 3B (or ABY - even better) head be? Imagine: a long stroke motor for good low end torque and 20 valves for high end breathing. Sounds good already... Any BTDTs? Oh, thnaks for the advice re: Quattro gear ratios. Rob
