Re: [TECH] 2.0 16v into an 81 "S"

["Jason87VW" <jason87vw@nac.net>]

I have a 1.8 head on my 16v now. It was origionally a 1.8 bottom end with
CISE Jetronic ingnition. I don't have motronic. That's why I asked what
parts I would need. Did you do your swap yourself ? How difficult was it ?
Did it kick A$$ ?
