Slow progress, but I think it will fit. (Here it's being tested on a spare parts car.)

One inlet tube in about the right place. The vacuum canister that operates the manifold changeover valves will need to be moved in position (as being held).

The throttle body will need to be placed at this end of the manifold, so requiring a new entrance.

I am wondering what throttle body size to use. Standard Insight is just 38mm, and with my power increase, I calculate maximum airspeeds through it of about 300 km/h. (Standard max would be about 170 km/h.) A 50mm throttle will reduce speed back to standard.

But I really don't know - there doesn't seem to be any tech literature around about matching throttle body size to - well, anything much.
