Iv had I4's v6 ,v8 and now flat six ,ranging from 1.8 to 3.6 L and 180bhp to 250bhp the I4 was a great all rounder the six's needed to be reved but the v8 did not have the most power but felt to have the thickest power ,I like the revy nature of the six's but allso liked that with the 8 you could pick any gear any rev and it pulled.
