As we are on the subject of N75 valves, it seems there is so much information throughout the various VAG forums as to which one is best, but without a definite answer ? I want to replace mine with a brand new one, but which one ? N75J seems to be the choice. My engine is a little bit of a mix up. AUM engine, (Rods done) injectors and inlet, AGU management / ECU & K03s turbo. Would would be best for my setup ? (Sorry for the hi-jack)
Just to add even more to the mix.. They can even be adjusted to alter flow per pulse rate so effectively upping boost that way if required Rich, if your engine has been mapped then you should stick with same valve it was mapped with as going to a different one can alter how car drives due to different characteristics N75J seems to be the choice tho but i personally can not see the point
