Kako se nosit motor mjenjac sa k04, imam isto 6 gti dsg ma stg 2 , pa bi htio slozit na k04, jel se isplati?

[@fedjadrndarski5606]

Bez problema. Ja imam manuelni, ali sam stavio pojačan set kvačila. DSG se mora mapirati da se nosi sa većim obrtnim momentom od 400Nm.

How was it? Ko4x or ko4 which should I go with

[@fedjadrndarski5606]

I bought K04x at almost same price as K04 and I am very satisfied how it doing. No boost lag, very fast transient response, it is capable to maintain 1.6 bar at 6k+ rpm which is not possible with standard K04. K04x drives about same as standard K04 at low rpm and mid range. When I bought K04x price was about 150 euros difference, so I decided to go with hybrid. Now you can buy K04 at discount for about 1350$, K04-x is about 1800$, that is big difference in price, in that case I would go for K04, especially if you have engine with weak valve springs (my engine isn't affected - no misfire at high rpm with high boost) .
