i saw an ls running brian crower stage 2 cams making 170 hp n 150 tq with p30 pistons i belive. then the guy put it in a b20 with some forged pistons and crower 405 cams. he was using a gsr intake mani with butterflies (he had it made to fit) and used the nitrous control on hondata to control the butterflies opening. it was almost like vtec! search on ht for it. the guys name was b19 i belive or somethin close to that. hell of a setup. jscushing (forgive my sp) on ht also had a nice ls setup.
