N75 Valves which one is better?

[Holksvagon]

I have a N75 H part# 034906283H Is this one good or should i ber lookin into a N75 J ? I have a 01 Gti AWW 1.8 T w/ Upsolute chip... thx for the info guys and gals:mrpimp:

If you are SURE you need one, get a J. The only reason I can see for doing this mod is if you are getting surging. If you are not getting surging I don't think it will help you at all.

I agree,

Only buy an n75 if you are having problems with surging. If you are having problems with surging, your safest bet is to buy a C N75. The H is pretty good too although your run the chance of having problems with overboost and your car going to limp mode (50/50 chance)

The "C" valve is still readily available if you know where to look ;-)

The "H" valve is the same valve that ECS tuning is boasting as their "race" valve and is good for an extra 2-3 psi. The "C" valve is a great upgrade for those who are experiencing some surging problems, usually after chipping.

Well, we were talking about a brand-new valve from the dealership. Yes, you need to go somewhere else to get a "C" now, people sell them used sometimes, etc etc.

The "boasting" about 2-3psi from the "H" valve is something I am EXTREMELY skeptical about. For every good story there is a bad story when it comes to this valve. I would avoid it if you are looking for a "sure thing". If you have a hundred bucks to "experiment" with, by all means try it and let us know how it goes.

Well I am running the "H" valve in my ar with great results. i have also installed it in about 5 other 1.8t cars both VW and Audi with similiar positive results. I have a few more on order and when they arrive I will try one in a 2.7t application for the first time and see how it reacts there.

Post a dyno comparison between a stock valve (with no surging happening) and the "H" valve and I will be less skeptical I guess.

Just put in the N75 H in a 01 GTI AWW w/ Upsolute Chip and I love it.... Power curve is so nice and it seems like the boost doesnt peak right up and then fade it stays... Pulss harder then the N75 F i had in there before.... IMO its a good buy

[Kor]

Do you have a boost gauge?

[Holksvagon]

nope i wish i did so i could tell for sure
