Audi TT MK2 Turbo Upgrade

[konceitedBastard]

I have a 2008 Audi TT 2.0 FSI Base Model Coupe and I want to upgrade my turbocharger to a K04 F23T Turbocharger. Can someone please tell me ALL the additional parts I will need, if a software update is needed and any other information that would be helpful? If anyone has done this...can you please share your experience. Thanks!!!

This might help but check the engine code https://r-techperformance.co.uk/axx-bwa-tfsi-k04-turbo-conversion/

Obviously it won't make the power on this website unless you add a whole load of supporting hardware. 

If you don't change the fuel pump at least change the follower if not already. 

Same with the PCV will most probably fail with more boost, rocker gaskets often go also.

My TT has the KO4 from the standard since it uses the CDL engine. I got compressor surge trying to get past 350BHP so I had to get a better turbo and ditch the stock KO4
