Hello

What is the correct part number of N75 J valve?

Is it 058 906 283 J?

Best regards

or is it 034 906 283 J?

or is it 034 906 283 J?

Think its the 034 906 283J, that's the one I am buying and popping on my mk1 vrs.

Same here, I have already ordered one so still waiting.... :p

J version is from Audi 200 and S2...

Best regards

av just fitted one and make sure you put it on right as you will pop the code 17963 up ..like i did

av fitted full milltek exhaust and cat with forge tip and dv and cai and no remap and it hits neally 15psi when i fitted the n75j valve

feels sweet

am i right in thinking that the n75 j is fitted as standard to the 225bhp engines or have i heard wrong??

You heard wrong, the F valve is fitted to the 225bhp which is the same as fitted to the Mk1 vrs

what are the advantages of the n75j valve over the stock n75 unit?

well better i say but the f type just keeps you standard and safe

well thats a downer as ive got a mate that works in a salvage yard will keep my eyes on ebay for a j then

only if your mate take insurance right offs...

thats exactly what they are

What I`ve read J version holds boost better in mid revs and must be installed "opposite" way to F version.

It was fitted to Audi 200 and S2 version.

Vrsjaw could you post some pics how you installed yours?

Best regards

the j holds more boost and doesnt tail off as the standard one does,should get one esp if yours is mapped.as to fitting its just the same as the standard one just the opp way round.

Was going to install mine tomorrow but glad I read this, installed "opposite" way to F version? do you just turn the valve around? I was going to do just a straight replacement.

Any pics?
