And to answer your question yes the TSI motor can handle the boost of a k04. Some have valve lift but there are new valves you can replace with and there is a guide on here how to check if you have the weaker valve springs. However its not that common from what i read.
Other than that the clutch on manual cars will almost defiantly slip on k04 lvls if not upgraded. Some people swear they are on stock clutch with no issues but a lot of people have clutch issues on stage 1. DSG seems to hold the power well and if slipping some people have found good use from the DSG tunes others have found better results in switching tuners.
Support mods are defiantly gold but the only thing needed for k04 is a intake that reads the MAF well and a down-pipe(Also new plugs gaped properly and coil packs). Those are the minimums. It is highly recommended you get a intercooler and inlet/outlet pips also.
yup. this sums it up. if you are running k04, make sure you have the right supporting mods or you could be looking at some issues down the road if you ride it hard. I'm planning on k04 soon, so Ive been getting all the right pieces in place. Find out what you have and then have some fun.
