Actually that would be too easy. Lexus wanted to make sure the 2UR-GSE 5.0L V8 had a balance of power and efficiency. The IS F evades the gas guzzler tax. Fuel economy on the IS F is beyond what the M3 and C63 AMG can achieve. Both of those cars have the gas guzzler tax tacked on to their MSRP.We have seen the 7A-GE and 5S-G(T)E conversions do some serious honda killing. WHat about a 3UR-GSE? would a 3UR-GSE be hard to do because of the direct injection? I hope not. A 5.7 L V8 would kill the C63AMG in the straights and be a very fearsome opponent to a M3(not that the F already is). Stroke that out(and maybe bore,depending on the thickness of the cylinder sleeves) and you have a 6.XL everything eater. Actually, why didn't Lexus just make a 3UR-GSE in the first place?
