Here is a nice pic of RS1's engine bay.

there is a nice small black hose connected to the very far end of the plenham, Is it the hose which can be plugged for de-acoustic valving

I didn't think the first generation 172s had the acoustic valve

neither am I, after seeing in some pictures of Mk2 RS's, There is a little hole which was plugged by a pin or stg else. I saw a similar thing in RS1's engine bay. Again not 100 % sure.

so far so good, nothing needs to be eliminated then.

Anybodys knows where can I find these very nice lookin inlet elbows, I regularly check ebay, was not able to find. Since I am from Turkey. Ebay is gonna be my best bet.

Thanks for the anws.
