Basic 6.0 Mods?

[Chanzfx4]

I am in the process of making a nice sleeper 6.0 I guess I have 4 inch exhaust with nothing. And was looking for mods to accomidate: I know of tuners and stuff but was wondering about like intake elbow downpipe I basically want every bolt on I guess thanks.

You won't see anything with just the intake elbow down, that would justify the expense.

The exhaust and custom SCT tunes will make you think you have a new truck. With the 6.0L you need to get a monitor, or a set of gauges, and keep an eye on everything. This will prevent costly repairs down the road.

If you're looking for bolt-on power, here's where I'd start:
Monitor/Guages: Edge Insight CS/CTS with expansions covers a lot of good info for the cost. You want to monitor EGT, ECT/EOT, Boost, and Fuel Pressure at a minimum.
Air Fitler: Stock air box is good for 500HP, want more air go with the S&B CAI.
Exhaust: Turbo-back 4" stainless, deletions of CAT/Muffler, per local regs.
Tuning: Custom tuned SCT, running either Eric's (IDP) or Matt's (GH) tunes.
Turbo: Powermax Stage 1, will support builds upto 500HP with injectors (this turbo will support 190's for a short period of time, but really shines with a set of 175's -play- or 155's -if you tow alot0-).
Injectors: Ryan Casserly makes the best 6.0L injectors out there. Depending on what power level you're looking at (155's ~ 480HP, 175's ~ 520, 190's ~550 HP)
Intercooler: Banks makes a good unit for the price, but its not needed unless you're having issues with EGT's. (This is also the only peice of Banks hardware I recommend on the 6.0L)
Transmission: If you're going big, drop the money and get a built 5R110 for a good shop.

Building a set up with 190's you'll want a built Transmission, the stock unit won't hold up long, and a Stage 2 VGT turbocharger.

You'll want to read up and get into the 6.0L if you're going to mod it, this is a very basic rundown of the common knowledge.

Thanks for the real thourough rundown on everything.

how nice of a sleeper are you trying to get power wise?

[Chanzfx4]

I would just like to have a duramax killer I guess. I never haul anything anyway

250cc injectors, tranny, compound turbos, Airdog 2, live tuning. Should give you the ability to keep up with a dmax. I'm kidding, that setup would outrun about anything.

colo hit the nail on the head. Use his advice with a limitless amount of research and you will have a killer on your hands. Btw, guages are most important. Get to know your motor before anything. I will add, get the undated fuel pressure regulator spring, and the 6.4 banjo bolts.

If you're just looking to toast Dmax's, you can probably get away with the 175's and the Powermax. One of the best builds, cost to benefit wise, crossing into the realm of injectors. 190's really require a Stage 2 turbo, and more supporting mods, and Transmission starts to require attention.

Real trick with the Dmax is the PSD requires a bit of work to overcome the fact the Dmax is alot lighter and has a 6sp transmission.
