Intake manifold.. ls2, vic jr?

Curious what your thoughts are on a ls2 vs vic jr? I am building my lq4 80mm turbo setup and already have a ls2 intake, picked it up since it has 90 mm TB opening. But really want a vic jr setup with low profile elbow. Any thoughts on this?

I understand the ls2 n/a is not the best thing, but for forced induction i thought it was decent for cheap. I have a comp turbo CT5 with a 80mm GT45 compressor wheel, triple ball bearing aluminum center section and a 79mm inconel turbine wheel. 1.15 AR, T4. Going onto a lq4 standard bore, stock crank, eagle rods, probe pistons, custom grind turbo cam (dont have psecs off top of my head) 317 heads.. shooting for 800-1000 hp through a M6. Running 93 pump gas with 100% meth

We picked up over 60 rwhp and lost 2 psi of boost when we swapped out an LS2 intake to a FAST 92 on the CTS-V here, back at the old shop that I managed. Bob
