Default master power sizing

Well since im riding a boat across the gulf of alaska I figured I would throw this out there for entertainments sake...

I am building an s-10 for street/ strip fun ( mostly street really ) and I bought an L92 to run in it. Forged rods and pistons ( 382 ci ) , 10.1:1 cr, stock heads and truck intake, custom cam for a turbo from texas speed, stock L92 heads. TH350. Dont really have a HP goal/ ET goal ( though bottom 10s would be swell )

I was wanting to run a MP t 76 but im wondering if its going to choke off the motor in the upper revs? I want decent spool down low ( strong boost by 3000 or so ) but I would sacrifice that to some extent to have something that keeps pulling hard to 6500 rpm +. thoughts?
Ive really been thinking of going twins but I just dont think its something I want to tackle on my first turbo build.

The Q trim with .96 a/r is the way to go with the MP76.

Call Rob at Modular turbo. He'll hook you up!

Go with a t78, it might be a little higher of a spool than in your OP but it will pull the whole way through.

You should move here! I need more people to work on my car. My buddy has a bagged s10 with an ls6 in it and back when I had my xtreme I had planned on something similar but ended up just dropping and shaving it.

The T76 is the biggest turbo MP currently makes. The Q-trim turbine is actually a 1.0 a/r, and 3" vband outlet. Would work very well on your proposed setup!

you think a 3" downpipe is enough for that many cubes? And yes, what about the 88, I forgot that beast was making its appearance here

You can step it up to a 3.5 right after the v-band if you want, but I've seen a 3" down pipe run mid 10's on a 6L in a 4900lbs 4x4 truck.
