LSVtec is definetly not all its blown up to be, it takes much more than a couple oil lines and a head to see good reliable results, like a vtec oil pump and god help you if your gona try to run the b16 cams on a b18, an last but not least the ls bottom end is built to spin to 6800 that isn't very helpful for an all motor project. I'de go with the gsr. I like the setep dohch22a4 described alot, Its got definate potential.
