I would say around 370CI. The turbo is more efficient then the old style 94's with F and G-trim's.

You run seperate pipes from each header to the turbo correct? If you look up a few posts in this thread you will see pictures of my buick v6 ta headers, I want to build a v8 set to mimmick these headers, basically a rear crossover to a primary rh tube that will go straight to the turbo, each port on the rh side will go directly to the larger pipe, Im trying to decide if 3" would work or if I need 2.5? I cant find 1 3/4 to 2 1/2 collectors, only 3" Im thinking that 3" would be perfect for the RH side pipe into the turbo, might as well use a 3" crossover as well?

a front crossover will be much easier and have MUCH more room.

I like the idea of a 98-101 for those cubes, I'm concerned about backpressure going forward as that's what probably killed my mid frame GT47-88.

Yeah i really dont see where a rear crossover will fit.... this is in a G-Body car??
If so id have to see the room.

Burns stainless has those merge collectors on there site..... most merge collectors are a prety penny $$$$

Im going with mild steel, then coating, it is a g-body car, im going to mock the engine/trans on the frame this weekend and get an idea of space, but with a front crossover it will limit the space for the IC piping and sway bar...
