Can't say I've seen many results from the k1 ha! The main thing I have is the cost of ct9 rebuilds or hybrids. alot of people don't even make 200bhp on them and then They say yea but there's almost no lagg! For sub 200bhp on a small engine if as little lagg as possibly is your desire just buy nice n/a ha! Each to there own on with there cars but some guy was banging on about how bad the lagg was on a td04 it made it un-drivable and I just wanted to slap him and say well learn to drive properly then ha! My first td04 glanza was 1.3bar mapped on a emu stock engine and was superb for windy country roads!
