Should I go with this and would it make any difference. It is 500.00
Brand new, Dodge Cummins Holset HX40 turbo. Cummins Part#4089328
This is not Chinese aftermarket junk,

Or will this work it is only 334.00
Upgrade EMUSA Super Drag HX40 Turbo Charger With T4 Flange and 4" V Band Exhaust Side his is the real deal.

Or just stick with the factory HY35 I believe I have.

 

you won't like the hx40 spool up is slower than your hy. but higher rpms are better

 

Ok bottom line. If I do the Quadzilla adrenaline and of course build my transmission to handle it. The Quadzilla states it will produce 415 hp and 880 lbs tq. What else do I need to do to my truck or will it actually make those numbers?
