duramax turbo upgrade
 

i have a 04 duramax and wqant a bigger turbo one that can run on stock injectors for awhile but i plan on getting a fass and injectors once i get enough money and wat size injectors should i get i was thinking going with a fass 100 and 100hp injectors and also can u adjust the fass pumps??? i plan on doing some sled pulling 4-7 times a year at the fairs aeround me and i do quiet a bit of mild towing so the turbo has to be tow worthy please help me

Are you going to be pulling in a particular class? Or is it run what you brung? Also what is your end horsepower goal? But as for turbos I would look into a danville 2.5 turbo, garrett stage 1 3794AVNT, or a garrett stage 2 4094 AVNT. Alot of it depends on what power goal and injectors you are planning on going with.

And you can run all three of these turbos with stock injectors and cp3 if you have efi live tuning. As far as injectors go I would into going 30-40% over injectors and a Fass Titanium 150 or a Airdog DF-165 for and lift pump and you will be golden.

goal prob around 600-700hp i want to stick with stock cp3 and i do tow frequently will all of these turbos be ok for towing its just a 28ft sled/race car trailer
u said 30%-40% over injectors bout wat hp is that??

30% overs are roughly 100-115 and 40% overs are roughly 140-150. The 40 percent overs even though they are larger would be a better route to go because they will help lower drive pressure because you don't need as aggressive of tuning to help spool the turbo. I would honestly shoot for the 600 range because that will help maintain reliability with stock internals. And that setup should tow great as well with a some other mods like watermeth or a intercooler!

ok well my plans are a turbo injectors fass idk wat size yet prob 100 are the fass pumps adjustable?? a water meth injection air intake straight pipe exhaust egr delte head studs efi live or ppe and some trans upgrades

Fass 150GPH is what size of lift pump you will need. And the tataniums are not adjustable but you dont need to change the pressure on these trucks. And with a intercooler, watermeth, efi, exhaust and downpipe, egr delete, and a built trans the truck will run great! That will be a great pulling/tow/ drag racing rig. You will also want to upgrade the front end with some HD tie rods and support kits

what about bottom end will i need rods pistons cinnecting rods?? cam?? ik ill defintaly need head studs

Headstuds would be a plus. But with good tuners that know how to alleviate drive pressures you wouldnt need em right away. But they are a good thing to have anyways. Rods and piston or a cam wouldnt be needed with that setup
