Default STS Turbo Specs

Can anyone know what turbo, trim and AR is used on the STS kit for the 5.3L LM7? What upgrades are available?

Thanks

i don't remmeber the exact specs anymore.

My upgrade was a GT35 61mm compressor, 68mm exhaust housing with a .68 A/R? The A/R I can't remember exactly.

Made great power and TQ but I swapped it out for a GT67 to see if that was what was limiting me. After more though I bet it was my heads that were killing power. Check their website or my sig for a dyno sheet.

The CMmotoring kit comes with a T-76. The STS kit is like a 60-1 or something like that.

I have yet to dyno with the new turbo because of some weird variance bwteen my left and right 02s. Hopefully he will have it firgured out by Mon. or Tue and I'll get some new #s. I am trying out the GT67 with a .96 exhaust housing. May be way to big but he said it spools very quickly on the street which is awesome considering it's size vs my 5.3L.
