if you want 5x.014s i would personally recomend a 64/71/14 charger or similar. or a twin turbo setup

get ya an intercooler out of a 6.0 ford and mod it in, it has 3.0inch outlets and more cooling capacity, ya want cooler denser air and these work well into the 60 plus boost range and worth the mod,,and a lot cheaper than buying after market, and find ya the pump side housing and wheel out of a turbo from an 8.3 cummins and put that on your HX 35 turbo, and build a hybrid, got one on mine and it handled all i could give it, and is still going, 300 K later,,,
