My sts turbo started making a funny noise a while back. Now its done. Should I upgrade to the gt67 sts sells or is there other options? The 60-1 made good power but I think I over spun it or something. It made 547hp and 600ft lbs on a dyno dynamics dyno, its a eddy current dyno. With the 45 shot spraying. The truck is a daily driver. I also have a ligenfelter gt2-3 thats going in soon. A little lag won't bother me I pull a trailor a lot and the little turbo I have actually builds boost a little to quick when towing.

 

67 here with wrapped exhaust, no complaints.

 

Thats a cool AZZ ride you have there Z06TED ... ( The Truck! )

 

I bet towing is what killed your turbo. If you want your next one to last, i'd recommend getting a different truck to pull with. Towing will skyrocket your EGTs and burn a turbo up real quick

 

I had a GT-76 on my 5.3 and liked it. Was at full boost at about 3500 RPM which isn't that low an RPM honestly but it moved a ton of air and it wasn't super hot either. I liked it but would recommend a GT-67 though.

 

I am taking the STS system off of my truck in a few weeks....I "might" be interested in selling the turbo separate. Let me know if you are interested in it, it is the GT67 with a .81 AR.

 

67mm would be good but I might even go 70mm.You want efficient boost of the bigger turbo but give up minimum lag.

 

I should mention that I had a tiny A/R to help it spool faster. But since it was a big turbo on a relatively small engine I never got close to out flowing the smaller A/R.

 

I have a gt-67 on a 5.3 (was on a 6.0, it spools sliightly later on the 5.3 but still very very streetable.

 

Hey Wilde, you gonna make it down to Sac on the 17th to come play with us at the track? Would like to meet you and check out your truck!
