Gt2871R vs 2x 9Bs

Just moved to AZ, lost a bunch of parts on my my project car (turbo liked, Y-pipe, SMIC pipes and front manifold)

Quick question, would a GT28 outflow the tinny stockers?

Was thinking of going with the 350Z manifolds, adapters and then trying to put the smallest single possible to keep the engine bay nice.

Engine is a stock rebuild with new head-bolts, metal head gaskets and a N/A block. I have a MS3 setup and was looking to run E85 and make about 400hp.

Thoughts?

You would be on the money if you used 350Z manifolds. You would obviously have to modify them to your application though. I have a buddy of mine who used the same manifolds when he did a single turbo conversion on his vr4.

For the turbo, I am not really sure. Someone smarter than me with turbos would know.

I suspect it would be pretty close, but with the single having a slight edge. Google GT28 dyno and you'll find many examples of low 300s WHP on different combos. You'd pretty much have to have 9B's on kill, pumping a lot of hot air well out of their efficiency range to get close to that. If you're looking for 400+ AWHP, I'd look at something a little bigger. There's plenty of options in that T3/T4 frame that would get you there.
