HKS showed their new twin turbo setups in 2021. They tried to have a straighter shot into the turbo and out of the turbo on the exhaust side.  Here are a few more pictures of a more complete setup in 2023.  The biggest limiting factor on the small twins is the size of the exhaust wheel you can run. The small housings can only take so big a wheel. A wheel of a certain size can only flow so much air. Since the compressor and exhaust are mechanically coupled, when you reach a limit on one side or the other, you are done.

I like the heat shields they are using on the turbo exhaust manifolds. We used a similar setup on Nicks R32 back in 2001.  The Wiggins clamps setup looks like the old Aussie touring cars. 

Exhaust flow vs exhaust port sizing, turbo inlet, outlet and cylinder capacity and more are all touched on in this interview along with casting vs custom fabrication, materials and a commonly overlooked consideration with aftermarket turbo setups, turbo bracing.

Big thanks to Ben Creswick for sharing his time at GTR Fest and we hope testing with the Inconel manifold applications goes well.
