Default Duramax turbo LQ4

Well I managed to get my hands on a brand new duramax VGT turbo. All the piping. Flanges ect... Even the software that controls the VGT solenoid. for FREEEEE!

Do you think this can be applied to an LS motor application. Im all about going different ways with my builds. Any input would be great.

How much power are you looking for? Not a very big turbo.

I bet it would do that on a 4.8~5.3L if you set it up to make the power early.

not really worth the time. it is only like a 64mm comp wheel, small exh wheel and really no way of controlling the vgt part of it. Too small, probably snap the shaft easily from barking the turbo. and back pressure would be really high. a guy i know used a vgt cummins turbo on a ls1 camaro and the back pressure was really high and choked the engine

To small. Would run out of steam real fast. Think about it. They run out of rpms on the duramax @ 4k. So that means it would do the same on a lq4.
