turbo
 

Im building up my cummins to stuff in my f350, trying to decide what turbo I wanna go with aurora 4000 or BDsuperbee. But how is the pdr hx40?

what HP goal?

63/65 or 63/68 may be a good match. Stick with an s300 based turbo.

a 62mm will support 400HP in a 1st gen

My goal is 500 im doing sticks denny t fuel pin stage 2, 3200 spring, colt stage 4 cam, valve springs, advanced timing and whatever turbo. And eventually p7100, port andpolish, water/method injection

you will want a 64mm

If you want not so much lag I can get you a 64/65/12 as long as you have a manual.

63mm may not cut it unless you have head work too. the 12v heads are restrictive.

Well im doing port and polish and. Cam
