isx turbo whats the story?

I have heard many commments that the design of a ISX turbo is a ^%@$ poor design. Im just wondering what the difference is between a stock ISX turbo and a after market one is??? What is the technical term for the isx turbo?

It is called a variable geometry turbo and usually the problem is with the actuator that changes the angles of the turbo blades. I'm not sure if there is a aftermarket replacement for this turbo. I maybe wrong but I've never heard of one. Somebody else may know.''italic text''

The design and concept of a VG turbo is sound and it works. But as with all things, when complexity is added to the mix, then problems can crop up more frequently. To paraphrase Commander Scott's comments in one of the Star Trek movies...."when you complicate the plumbing, it is easier to stop up the drain". And, of course, that complexity comes at a price. I can get a very good non-wastegated, non-VG turbo, for $700. The ISX Holset VG turbo, you will pay $3600 just to pick it up off the parts counter. And since the VG turbo on the ISX is also controlled by the ECM via the actuator controller, I am not aware of a viable aftermarket alternative.

i think if you get your ecm reprogrammed there are after market turbos available. Didnt you block off your egr? once you blocked it,did you plug it back in?

Yes. Blocked it off early on. Then put block between tube and intake. Had it in Cummins later, they plugged the EGR back up. It must have had carbon/rust/whatever build up, it died in the closed position. That was over 400,000 miles ago. Still sitting there, dead, and looking stupid. Doesn't matter. Truck goes bye-bye in 4 days.
