This maybe a daft question so feel free to rag me if it is..
I have seen plenty of posts on the forum which explain the advantages of fitting the N75 'J' valve on the 1.8T engine due to its higher spring load which allows more boost. (I believe it is fitted to the 225TT)
Is there the same type of modified OEM valve available for the 1.9PD engine? If so I'd definately be interested in getting one fitted!
Let the mocking commence....
