There are several special edition versions of the MK6 GTI available around the world with EA113 engines.
You also didn't say GTI, nor does the title of this thread. It simply asks "Differnece between the TSI And FSI" Stop twisting it to somehow make it seem like you were right, you weren't. Accept you learned something and move on.
The bottom line final and only answer is one is used by Audi and one is used by VW. No matter how hard you try and make it anything else that is all it is.
The Edition 35 is the ONLY one that uses the EA113 w/ K04 in other markets. That wouldn't apply here.
You are just being a jerk at this point as you knew exactly what the OP was talking about.
The title may not reference GTI but the OP initial post specifically does specify his friends MKV GTI and HIS MKVI GTI.
"So i was talking to a buddy of mine and
he has a mk5 gti with a fsi motor and he told me he had to get s3 injectors and a hpfp for him to switch over to k04. My question is on
the mk6 gti with the tsi engine you dont have to upgrade those things when going ko4 right? "
I did learn something. Never said I didn't. But I also exactly answered the question that was asked.
MKV GTI = FSI = EA113
MKVI GTI = TSI = EA888
Don't make it into something its not. We don't care that you can use wikipedia. If anything you completely misunderstood the question as he wasn't asking the difference between FSI and TSI but rather the difference between MKV and MKVI GTI motors (or in effect EA113 and EA888 motors). He didn't know the engine codes for each so he used what he saw on the engine cover as the reference for each motor. The nomenclature had nothing to do with his question.
