hahhaha i cant believe u want an LS motor! ur b16a can beat an LS anyday-stock to stock, how do i know? cause i race both my friends LS teg at the track and on the streets, more track than street. my best time is 15.534, my friends best time were 16.2xx.
i also like racing them on the highway too, drop it in 3rd, hits 6K RPM, i will hear them sift while i pass by still in 3rd.
learn to launch, not just dropping the clutch. LS has lots more low end torque so first gear you will be playing catch up, second gear you will begin to pass, third gear u done pass him.
i also raced an LS/VTEC, i gots to say those are awesome! the guy ran 15s but his best time was 14.7s-said he has still tune it.
oh a thought, my other friend drives an altima, he best time was 16.1, he race my friend LS teg and beated him-over and over and over. maybe you should get an altima engine instead!
