when i built my b20vtec for jrsc my tuner recommended using a stage 1 NA cam over a turbo cam. i ended up using the blox A cam because it was cheap and friends had success with them. the car made decent power, but i dont really think cams make a lot of difference with the blower. there are guys with stock gsr and itr motors that made near the same power as my built b20vtec did on the same psi. i used low comp pistons though, so that is part of the equation as well.
im sure either a stage 1 NA or stage 1 turbo cam will be work fine. i can tell you that i gained 10whp on the dyno by adjusting the cam timing with the jrsc.
