where would 6 cylinders have the most advantage over a vvtl-i or dohc vtec 4 cylinder engine? would the 6 cylinders pull away at high speeds like at 60-100, or would it pull away at 0-60. for example, lets use these cars: toyota celica gts, lexus is300, honda prelude sh, non-turbo nissan 300zx. the magazines have shown that the prelude for example can beat the is300 in 0-60. what i wanna know is, with better 0-60 times, does that mean they can either keep up with or pass an is300 or 300zx, in 60-100 times? i guess pretty much the question is.. does the 6 cylinder have greater advantage at higher speeds, even if the 4cylinder can outrun it in 0-60?

okay... but how would u explain a GTS taking out the is300 in the quarter mile? the speeds may not reach 100 but it's well over 60. do u think a gts could take out a non-turbo 300zx in the quarter mile? i doubt it. but so shouldn't it be like this: the more sportified the engine or its parts are, the better performance it will get? im talking about 3.0 liter 6 cylinder engines, versus 1.8 to 2.2 liter 4 cylinder engines with VVTL-i or DOHC VTEC.
thanks for ur input erick although it didn't tell me much, based on the fact that the gts outperforms the is300.
question for viggen: so where is that powerband on the gt-s?

isn't one of the advantages of having vtec, or vvtli (one of those), is that u get a have a flatter torque curve? or does a flat torque curve not matter? and what does the IS300's or even the 98 Supra's VVT-i do for the output of their engines?
[From TEG: Well, it depends on what sort of different CAM profiles they design in, but VTEC and VVTL-i vary lift and tend to be done to increase high end HP. VVT-i and the BEAMS system used in the IS300 is done more to move the torque peak lower in the RPM range. ]
