Any Twin Scroll experiences?

I'll be starting the installation of a Twin Scroll T4 Borg Warner internal wastegate on my '97 NA. The idea started with the excellent behavior of the BW Twin Scroll in my Mini Cooper JCW which has no lag and is very small.
Anybody here has installed a twin scroll on a non-VVT engine and if so how did it come out? Having talked with the main players in the turbo kit manufacturing area I didn't find anybody interested in prototyping a kit for a 20+ year old engine.
So I'm left to my own resources, something not foreign to me going back to the first Ford Cardinal-Saab V4 turbo which I co-authored a very long time ago.
Any ideas will be much appreciated.

Not yet anyways. The 7163 is the smallest to get a twin scroll turbine housing so far IIRC. IMO the 6258 and 6758 wont really benefit much from the extra complexity and weight required to make a twin scroll miata turbo manifold. I think with all the extra bends required to get the runners to the right spot on the collector at all the same length the tiny advantage you'd gain from being twinscroll would be lost in head loss.

Isn't Fae running a twinscroll BORGWARNER S366? He's pretty much our resident ALLOFIT massively oversized turbo guy, you might want to look him up, I'm sure he can drop some knowledge on you
