2004.5-2010 6.6L GM Duramax LLY, LBZ, LMM Stage 2 Turbo Upgrade Kit
Garrett 773542-5001S GT4094VA
For a small increase in price over the Garrett stage 1 you can get a turbo that will support as much power as the stock rods will safely handle! This direct bolt in turbo is capable of supporting 575 HP, which requires a built transmission. If you want a great turbo upgrade for having fun and working hard with the popular over the counter power upgrades and beyond, this is a good choice. The Advanced Variable Nozzle Turbine (AVNTTM) makes these turbos run like a set of compounded turbos. You get quick spool up and good flow for maximum power. You do not have to sacrifice towing ability or performance with this all around turbo.
