[TurboKraft]

Hi, I think you contacted us about this project via PM/IM/similar?

We have those catalytic converter flanges in stainless steel.

We make similar low-boost turbo systems for the 964, and they spool very early and linearly. 335whp/320wtq at low boost on 91-octane with VERY conservative timing and fueling.
We always use stand-alone engine management, usually AEM Infinity, and always intercool them. We have fabricated air:water intercooler systems for the 964/993 and can make one for you, too.
