[beezasport]

whats the best alternative for this valve..i've been told a j seriese vakve...where can i get one...dealer
cheers

 

[cordobabrendy]

stick to the standard f, tried and tested others mate, searchy.

 

[beezasport]

had a look in search but its finding allsorts lol

so is the standard a j or a n75?

 

[cordobabrendy]

the valve itself is called n75 valve, there are several variants such as the n75c, n75f, n75j, n75h etc but they were designed for different versions of the 20vt engine, stick with the standard f variant if its for a normal leon cupra/r.
(if you dont know what it does, dont play mess with it)

 

[beezasport]

thank you very much for your help!!
just come from another forum and this forum is so much more helpfull and quick
thanks again!

Yes, I second what CordobaBrendy says, stick with the N75F.

i've just had an ECS race N75 put on my LCR, it holds boost higher up the rev range than my standard N75 ever did.

The ECS 'Race' N75 is exactly the same as the N75 J variant. Although you probably paid a little more as it contains the word 'Race'

 

[karlosR]

really? i was told different to that........... i paid what i thought was a reasonable price for it so i don't feel hard done by or out of pocket.

 

[RobM]

It's the same thing mate

How much did you pay?

 

[cordobabrendy]

karlos, searchy for my rolling roaded tests between a few n75's, the only difference between them was the fact that boost came on a little earlier for some variants, making the others "feel" like they were holding boost later.

 

[HarveyGTI]

variations is between the different letters is some N75 valves apply the boost more aggressively so of course making the car feel quicker

no such thing as a "race" type valve

issues with more aggresive type N75 valves are they can make the car go into limp mode, requiring the battery to be disconnected etc

to be honest i played around with these valves for some while, and i would just stick to the normal one that came with the car as the difference is marginal in a standard car

even if it's chipped etc, its still not worth it as of course the chip then takes care of more boost etc etc

i had mine fitted before i had my LCR re-mapped and there was a definate difference. i've been told that there is a difference between this and the J valve. my understanding is that the J variant comes from one of the audi S4 engines and doesn't seem to work very well on the 1.8t engine. like i said though i was told this so i might be wrong.

have a look here http://www.ecstuning.com/stage/edpd...di&model=TT+MKI&submodel=Quattro&engine=225HP i don't believe the extra power gain claims but it has made a difference

I fitted the J at the weekend and so far so good!! I like it. I was told the J is good if your car is standard, which mine is (at the mo) Im a bit worried now after reading this thread?? Maybe i will get some problems?? Hope not. Just have to wait and see i guess.
