What's the largest T4 turbo that would drop in where my TC76 is now?

same boat as you trying to get more turbine than what i have now out of my tc78 on a 370
only thing that will be physically even in the same realm for size with a bigger turbine will be the GTS wheeled turbos or the Comp 80/79 with the 100 trim straight cut turbine
I am lazyand dont feel like having to change anything, so i am just sending my turbo to Comp and having them cut a 1.32 hotside to fit the tc78. and see the results of that
had been thinking of trying a clip on the current turbine but can't find enough info of it being done on larger turbos to take the plunge
and the BW T4 stuff is still HUGE compared to the TC

1.) 3.46
2.) 15
3.) LS6
4.) 60s
You run a 91mm T4 right? How big is that monster physically, compared to say a PTE76?

I am pretty sure the 76GTS uses the same turbine wheel as the Garrett GT-42, which is 81.3mm (82mm). Sounds like the 76GTS spools a little quicker because of a lighter modified shaft, here is some info

Hmm, so that prolly brings coolant along with it. If that's the case, no way lol. I'll look into it more though. PTE76 still looking at the top of the list as of now.
I might go ahead and buy an S475 and see if I can make it fit somehow. It's huge but it's such a bargain for it's capability. And if I can't use it I could just resell it or put it on something else. I have been thinking of a low boost setup for my 4.3L Blazer haha...

same size as a gts76 I think, just have to run a larger down pipe. I'm gonna pick one up to try the fit on my Z06 this week. I'll report how the fit looks compared to my 76
