If that's the case, I would go with the last cam you posted. Isky 231-TA Turbo Cycle A
7 PSI is not much boost pressure, you can really feel it when you see 10-12 PSI. Don't get me wrong, you will feel 7 PSi also, just kinda ho hum with only 7 PSI, that 7 PSI is at the point where you are just going to want more & more.
