I'll give you an example of one .. Chris Corkin's ( tencentlife on thesamba ) .. his 'better 2.2' has a mild cam and he runs headers on them .. so 3 performance enhancements that I am aware of .. increased displacement, a little better cam .. and an extractor type exhaust system ... ( which I don't recommend ) .. didn't get to drive it much as the van wasn't registered I put it in for someone .. but there's one example.

2.1 liters is plenty to work with. there are 2.0 liter 16 valve VW inline fours pushed to 400 hp with turbocharging and other enhancements. ECU's are worked on .. though I am driving a suppossidly chipped one on a Digifant 2.1 system .. and the only thing really different about it is the fuel pump is on any time the key is on, which is unsafe. It doesn't really go better.

there is another VW engine that never was able to repsond to performance upgrades much, according to articles I have read.. the audi engine in the Porsche 924 .. not much is gained on those I don't think, and the market would be pretty small too I'd think.

Yeah, why doesn't someone make better flowing heads say for waterboxers. ? I saw a drag racing Bug engine, in a VW Bug ..in the UK.. guy put 4 valve subaru heads on it, OHC too. Ran real well.

a few waterboxers have been turbo-ed ..not with any outstanding results I don't think though.
