02 cummins gen 2 · 11-02-2009, 07:24 PM

i want to run a custom s300 turbo and a smaller one for a primary but i dont know what works best i heard the stock hx 35 works well or a k31 but if anyone has had luck with other combos let me know. i want a weekend sled puller and still pull my gooseneck trailer. i got and 02 cummins 6 speed manual.
thanks

What kind of power are you looking for? We need to know hp goals before reccomending turbo sizes.

With twins the primary is the larger turbo(bottom turbo) and the secondary is the smaller(top turbo).

i def want smarty and maybe an edge comp box to stack with. never built a cummins up before so not sure on whats good for the gen 2 24v's

Gauges
Liftpump
Drag comp
150hp injectors
62/71/14 or a small set of twins

That should be close to 500hp and still tow ok
Cam isnt really needed @ 500hp, but would help spool and egts some.

62/71 will be good. you will be close to 500HP with the set up Matthews8pt suggested
