911 Fan, Sharpbuilt or CSP

[Ti-Guy]

I want to install a 911 fan on a type 4 engine.
I already bought the cooling fan.

I hesitate between the Sharpbuilt and CSP kit.

The CSP kit look to be high quality but since I’m from Canada and CSP is from europe. I don’t want so send my engine overseas to CSP just for machining.
Is someone has the required dimensions for machining the engine for a CSP kit.
Is the CSP fan sit in the same position as BAS or other brand that required the same modification to the case? I’m asking that because I found a drawing for the BAS shroud and maybe its the same for the CSP.
I know that going with the CSP, the fan housing will required to be machine down to 260mm.

The Sharpbuilt kit required machining AND welding.
But what I’m not sure with the Sharpbuilt kit is that I don’t know if an integrated oil thermostat (like BAS) will fit between the engine and the shroud.

Any body has experiment with one of this kit.

Any feedback welcome.

Thanks
