911 Fan, Sharpbuilt or CSP

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

I have a Sharpbuilt on a 2.7lt type 4.I do not understand what you mean about the oil thermostat.Mine was fairly easy to fit and it was very well made.I have the one with the air duct to the oil cooler in the original position.I have found that this system by itself does not cool the oil good enough.I have a friend with the same system on a 2lt Type 4 and he has fitted 4 head temp sensors and all is OK there-but the oil is a problem.I'm wondering if the crank pulley was a bit bigger-it may be better.I am going to get one machined up to try.I used a sandwich plate under the oil filter and used another Type4 cooler behind the back wheel with a Bus heater assist fan,which is switched on by the ECU at 95c and it cuts out at 80c.It's been in the high 30'sC/low 40'sC here for a fortnight and I have been using it a bit and the oil temps are looking good now.If I was doing it again-I would use a big cooler and do away with the one in the original position.

OK-I understand now-as I said,I used a similar item,but it goes under the oil filter and opens to allow oil into the cooler.I made my own engine pipes and modified a Bus extractor to suit and have 2 mufflers under the RH mudguard with a tailpipe out behind the guard.
