is your N75 bad? or you just looking to replace/upgrade it? the N75C is the stock one that comes with our cars. IIRC - the N75F is the upgraded valve that the newer cars come with.
Some people also get the N75 race valve.
There is alot of info on here regrading upgrading your N75 and the pros & cons of doing so....

Enter Race N75 on the ECS search and it will take you right to it.

I run one in my '99 B5 (AEB) and really like it. A little extra inital boost...[drive]

yeh i got an AEB too. ive heard mixed things about the race valve esp on our cars (aeB). what were you boosting to before the valve? what about after?
o yeh..what setup are you running? K3..K4....?

I'm still running the origional KO3 now... I gained about a psi or so of extra boost (spike 17-18 psi with APR) and it seems to come on a little stronger/earlier too. I have had no problems whatsoever with the N75 race valve in my car.

Running one with a KO4, I think most people would say more than likely not a good idea.

thanks for the input guys... i've bought and install N75 race from ecs. now i'm thinking of adding a chip. but due to budget i can't afford a high end ecu. Any recommendations ?

Look for a used chipped ECU in the classifieds that is compatible with your car – model/year.
You should be able to pick one up for a decent price – compared to that of getting a new chip
