looking to upgrade turbo.. and trying to find out whats best to go with for my application.. I have an 01 cummins 2500 six speed. So far I have quadzilla programmer, 120hp injectors, air dog 150, intake and horn.. I do tow with this truck and use it at my job so i need something to work well with that.. i have looked into compound turbos but also looking into single.. whats everyone thing is best.. any help would be greatly appreciated..

 

A 63-68-14 is a good turbo for my truck I hit 50 pounds of boost and egts are a little high but not bad. I got my turbo from torque diesel very good people.

 

We have the 63/68 in a T3 hx40 14 non gated for under $1000, 12cm gated is also available. A 60/68/14 may be a better option since you only have 120hp injectors. with a 63/68 you should be able to support low-mid 500HP and could go up to 175HP.

 

really depends on your power goal.

I personally run 6x.013s with 357 over 475 compounds and daily drive it.

it does haze and puffs a little smoke if you don't baby the throttle, but it is very snappy and responsive. egt's stay well under control.

for a rig that tows twins wiht some 7x.012s should be quite a bit cleaner at idle and under acceleration and be very powerful

definitely hit up jacob for your turbo's

he's a great guy to deal with!

I bought my turbos, twin plumbing, intercooler boots, some of my gauges, boost bolt, clutch, etc from jacob

injectors from weston, fuel module from jamie.

 

I would/will go for a 57/65/12 over a S400 or a Htb3.So it spins up fast.
As the 57/65/14(SuperB) I have now spins up 400rpm later than the hx35(56/65/12?)which I think is significant with the 6speed I also have in my truck.
With the hx I had 15psi at 1000rpm, with the SuperB I have 5-6psi at 1000rpm.
Hx(32psi) fully spooled at 12-1300rpm, superB(45psi)at 16-1700rpm, so I think the smaller exhaust housing and compound will be best.
