T4 TDI performance upgrade

[stef38]

hello down there
a lot can be done to the tdi, but if you want to keep it simple and in a budjet, simply change the nozzles, i did it to my van and you should have seen my smile when i went back on the road
i used the 4 cylinder AFN ones, they have 5 holes of 0.205 mm.
you can then go another few steps, 0.216mm from the 150 hp van, and so on.
the first nozzle will already wake up the van, the other steps require some chipping to up the boost pressure.

Thanks for the info guys, I live in Europe for 9 months a year so I think I will get onto the UK sites and grab a set of the larger nozzles and bring them back when I come back later in the year.

It will need a retune by the sound of things to get the most of the change.

Should be a good mod
