Turbo upgrades ?

[jim659]

Any vendors making a higher flowing turbo for these LB7s yet?

ATS, BD and possibly others are in development for a performance oriented LB7 turbocharger. JK has experimented with different compressor housings and possibly other turbos.

I know ATS came close with a possible release date then backed off. Anybody close or just doing R&R?

The prospect of the actual R&R job isn't inviting to me, let alone most D-I-Y guys.

Been experimenting here and there. Nothing to write home about yet. I've had a mod wheel in mine for over a year now...

I have an acquaintance who claims to have a 2004 LB7 with a GMC-installed GMC-twin turbo. Because the parts and labor are GMC, the warranty is intact. I was going to start a new post today asking if anyone had any info on it until I saw this post. He said the difference in pulling his 37' gooseneck fifth wheel is amazing.

I would love some info on that setup.I wonder if it's just two of the same stock turbos set up for towwing or a main and secondery for a serious power upgrade.
