5E Suction cup Tuning

Moin people, I wanted to help my old 5E to achieve a little more performance… from my tuning time in the middle of the 90s there was a long rumor that this should simply go on at the 5E with K-Jetronic soooooo. Supposedly one should install the throttle flap of the Audi 200 Turbo (successor type 44) with 182 hp and Bosch injection nozzles of the E21 BMW 323i… Unfortunately this seems to be stupid chatter or an eternal myth… it may be that the nozzles fit, but the throttle flap is defin It is not possible to install it in the 5E suction cup. Has anyone heard of this story, or does which throttle flap really fit and what it could do? Greetings from Hannover In the appendix a picture of the car which is to be made a little more quickly(te)
