OK I am looking for some independent advice and where better to come to, than here.
So my installer is strongly suggesting that I go GT2871 (he has a K04 G5 GTI that runs a 13.28 1/4mile and K03s POLO GTI that runs a 13.71 1/4mil) and up until recently I was defiantly going to do so, but most of my buddies have been suggesting I go K04.
I currently have the AGU motor which has about 250000 KM on the clock. I do plane on doing the motor before changing the turbo and fitting S3 cams and injectors.
Although my Audi is not my daily driver I do want something that is reliable and can do 1000km trips at an time. I also want something that goes like hell when I want her to.
So again GT2871 or K04 it will help if you can support your choice.
