other people are running the same set up as me with methanol and are over 500 bhp
would like to do the gear box and then a wagon re-shell with abw arches
I think for the classic you need 4 ports.
3 the same size
1 for left rocker
1 for right rocker
1 for the breather next to the turbo
then 1x bigger one to vent to atmos
