Ok, Well I am now shopping for a bov for my '90 with a '95 motor swap. I will eventually be at 20psi. I love the hks ssq, but not the price tag lol. I was thinking of the turboxs rfl, they sound good and price isn't to bad. I feel retarded for asking but i need two of them, correct? Also, will i need to get the hard piping kit or will it work on the stock piping?
