Default Divided Turbo Manifold

Is anybody out there making a divided turbo manifold for the S2000?

I have seen tons of normal (non-divided ones) ones, but never a divided one. I would love to see what happens to the spool of the GT3071R and GT3076R when paired with the 0.78 a/r divided T3 housing. I'd also be interested to see if a GT35R in a divided T4 housing could equal the spool of my current GT3076R while making more power.

Twin entry .. has been on MR2 Turbo's and Celica GT4's as stock.

Really help cut lag down.
Think it's the same as "Twin scroll" that Evo's now have. Took their time, Toyota were doing it in the 80's

Divided manifolds are designed to be used in conjunction with paired cylinders to provide the best boost response possible.

The problem with the S2000 is room - there isn't much. If AC and the fuse box were not a concern one could be designed, but hardly anyone will part with and/or relocate these. Twin wastegates provides the best performance but without giving up the above amenities, it's difficult to properly package two wastegates.

Some examples, on a Civic with a GT42R:

Yeah, I doubt we could be able to fit one in our cars unless it's for a full out race car or if someone doesn't mind butchering thier car.
