hi people iam sure this has been coverd before way more than once. i have a 1999 vw golf mk4 1.8 n/a 20valve manual engine code is agn iam under the impression that it is the exact same engine as the gti minus the turbo please correct me if iam wrong what iam wanting to do is swap a gti engine into mine and wondering if there will be much involved considering i shouldnt really have to swap anything else other than the engine and ecu also stock for stock apparently the gti has only 17 more kw any info would be much appreciated
