i have a couple of turbochargers from a 3126 c7 cat with a front compressor wheel measuring 62mm and another being 64 and another being 66mm. would these work like a htt turbocharger they look really close alike. and they are wastegated and have a 4" exhaust and from what i could figure out they have a 14 cm exhaust and a 65mm turbine wheel. is their anybody that could help, if so please do.

When you find out if they work, sell one to me! I think they do not have a divided housing though, which would create pulses of exhaust flowing back into the other three cylinders' exhaust manifold. But might work, maybe someone has already experimented. Do they need a water hook up as well, or just oil?

just oil, and they all have a divided housing just like my htt 62/13 they are really close

kinda off the subject but how do you like your twin set up on the 99. i just put the htt ss on my 97 and was thinking about doing twins sometime. did you fab your own plumbing?

ya they are sweet i use a k31 for driving and towing talk to ronA he is the man when it comes to turbo knowledge

Do they have water cooled turbine casings?

no not any water cooled as of yet i have saw a couple that looked to be water cooled.

It might hurt spoolup a tad but that's about it. Many 4-6cyl turbo applications don't use split turbine housings.

Isn't the turbo off a 3126 basically a S-300

i got a cat turbo for sale would make a great buttom turbo or a huge single if you did a custom setup

I have been told they have a 71 turbine wheel.
Have you got a way to find out?
Yes, they should work although it probably won't have the popular hx-40 flange for the downpipe.

ya what turbo do you have crab, there is a big rig yard around the corner and i can get tons of turbochargers for like 250 bucks just the nice ones are like 450 -700 thats what i paid for the c7 chargers but they are nice.

Thanks, no turbo expert.

It is just that I do gaze longingly every once in a while at one we have around here. It is on a 600 ci Cat that powers a fire pump. The turbine casing and the exhaust manifolds are both water coolded.
