Has Anyone Got A 3.0 SC Injection Stripped At Present?

[gavinc69]

Hi guys, I need some help from someone that has got a 3.0 SC CIS injection stripped.
I need the diameter measurements of the air sensor plate and throttle body shown with the red lines below or even the openings of the black moulded bonnet that connects the two :




I am trying to buy some silicone 90degree hose to fit in place of the black Porsche moulded bonnet so I can turbo the car.

Thanks

Airflow sensor OD 127mm. Throttle body OD 80. From a '78.

I didn't mention the car is a 1980, but hopefully there is not difference as I have never seen the BAE turbo kits with different size bonnets for different years.
Thanks very much for the info, it will really help out.
