Thinking about sequential options

Early 350Zs were known to have weak gearboxes, after the first 1-2 years, the 6 speeds hold big power pretty well in stock trim.

I talked to Bryan at BNR a couple weeks ago about making a tubular SS manifold for their stage III's. He said that the manifold isn't the main restriction point, it's the turbine housing for the secondary turbo. He also said there are some housing from a 300zx that would work great with them, but he doesn't think they would go about 450 hp with the new housing and tubular manifold.

Maybe a tubular manifold and true GT28's would get to higher hp. I don't really know what was done to make them fit the stock housings. I kinda want to try something with two GT2871R's. Need to get more money first, though.

I'd be happy with 400@15 with a sequential system, and I've never seen that. If it's as simple as a secondary turbo housing, I'd like to see the proof.
