my point in saying "a good running B16a" was to make the point that a b16a running well will always be faster than a strong ls motor. 160hp vs 130hp in this case is no contest, plus you have more power over a wider power band. on top of this, boost and vtec works EXCELLENT together and makes more power. your b18's run out of power at 6700rpm while the b16a will make power all the way to 8200rpm. once you see b-series vtec/turbo you will never want to go non-vtec turbo unless you have no other choice. now i'm not saying non vtec turbo setups can't be fast, because they can but its simply a better setup with a vtec head. these head's flow better, rev higher, and make more overall power...end of story.
i think solreaver's example of the b16a being slower was due to poor tuning, a bad driver or a motor that simply didn't have good compression.
i've seen an all motor b16a/hatch go 13.7@97mph. now if anyone has timeslips that put a b18b/a in the low 14's, i'd be surprised...unless that b18 has a lot of work.
look at my setup if you want anymore proof, i have done NO internal work, am using an ECU that isn't designed for my car, and have only intake, header, exhaust and i put down 152whp. with tuning, i'll put down 160-165hp and should be right around 14.0's...with a b16a that has no work done to the internals at all.
