picked up a 91 gli cheap due to it having a blown head gasket under $300 and was going to go about fixing it but, a friend of mine had a 1.8l 16v sitting in his garage from a previous project. the only thing he didn't have was the computer which i assume was different then the one in my 2.0? i'd like to use his engine as it has aftermarket cams and also the pulley. what other then a computer for a 1.8l would i need? the engine he has is complete and came out of his 88 gti!
