How to install N75J valve??

[Petrina Polo]

Hi,

Just received N75J valve in mail from UK. How do I install it.

Someone said its installed opposite to the stock N75?

Is it a simple case of replace each hose as per stock valve or does this valve work differently??

I don't think you need to install in reverse (please correct me if I'm incorrect)

Ebay maybe

Pretty sure you need the J one

This originally fits Audi 200T, S2 3B and UR Quattro RR engine - IN STOCK ready to ship

Quick reference:
1x Genuine VW Audi WGFV, the so called N75, J version

This is where i bought it.

It comes in an envelope wrapped in plastic, no instructions etc.

Yup, from Fleebay. Pretty quick, seems good.

I've also put in the Festo flow controller, but don't recommend (maybe after i've got it all sorted i'll think more highly of it) if you've got a tune done.

N75 just needed pliers to open spring clamps.

Still took me 20 minutes, but i'm not much good with the tools.

not to be sounding like an utter dolt here , but what benefits does replacing the n75 do?

What does it do?

Its a solenoid that is controlled by the cars engine ECU to adjust the bleed rate on the control line to the wastegate. The J version is often fitted to 1.8T cars that have been 'chipped' to provide a little extra boost. This is not the intended application of this part, but many people say this J valve has worked for them and given more turbo boost. Generally speaking, the J valve only works on chipped cars only. If you have a standard ECU, this part may not incease boost performance.

Does that kind of help

Thanks VW Thunder, as usual there is someone who can explain in mechanical terms what i've done (all i really do is copy)...

If it's the J valve, it is installed in reverse to stock valve, I know I've been lazy but I will take a picture of mine with the part number 2moro. I fitted mine under recomendation from Seb, It was purchased from Five Dock VW who stock it especially for Seb. I used to work there and drilled Seb for info in the early days before a reflash was available. Joe

For fitting follow these pictures - https://www.peterbeers.net/vw_roadtr.../N75J/N75J.htm

N75J is NOT fitted in reverse to stock valve, it's just that the electrical connection faces the other way when it's in position - but the stock wire is long enough to reach.
