I see a lot of engine conversion intake plumbing with sharp 90s into the throttle body. I personally will try to avoid this with the largest radius 90 out the throttle body I can find and then a 30 deg to correct for the angle away from the intake side.....currently I am eye balling it and have not measured the engine intake diverter tee angle.

Interestly I have noted pitting on the inside of my low time cayman tb, coincident with the outside radius bend of the cayman diverter tee and intake path. This gives me the feeling that presenting the air flow straight through the tb may have some value; less turbulence
