Just bought a very tidy 1988 205 gti and I'm in love.
I was wondering if anyone can tell me the compression ratio of the aussie 205 gti as I've heard it's lower than the Euro spec. I apologise if this has been asnwered elsewhere - I did search but couldn't find anything.
If it is lower, what creates the variation? i.e. piston compression height, bigger cylinder head chambers.
