I think it only came with a green and blue and a red spring. I think i should just use the softest of the 3 springs. How much in the n75 valve?? I also heard the a j-valve was the best one for me to get??

 

First your gunna want the stiffest spring, and Id say the n75h is better but its up to you

 

ok sorry... mine came with the kit.. the green spring is gonna be too soft for you.. that could be your problem..

 

My diverter valve didn't come with the yellow spring. Could that be the one that is in it already? If not i guess i'll try and get another one from the website?

 

I know from my personal experience:

Blue: Boosted at around 12PSI @ WOT, very smooth through the whole power band.

Yellow: Boosted at 15 PSI @WOT, still smooth, a bit of surging between 2-5 PSI.

Green: Boosted at 21 PSI @ WOT, puts you back in your seat, surging occurs but now that I have gotten used to how to drive the car its been great.

Also, I swtiched from 91 to 94 gas so that could be making a difference.

 

I dont' know about the yellow one. But am i putting out enough bosst for one of the other springs to work cause I think the one that is in there may be the yellow one but i don't think its strong enough. But it could be a different problem entirely.

 

copied from forge's website.. i may change out springs.. and see what happens with my DV .. there info may be wrong [&o]

"Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit.

Your valve tuning kit you will find four springs and three spacers.

The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest. The spacers enable you to fine tune the settings between two spring tensions if required.

We normally supply our valves, unless requested differently, with a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the valve characteristics to suit a given application.

If you are finding that the valve is dumping more than required or you are loosing boost pressure it is normally an indication that a stronger spring is required. Conversely if the valve is failing to dump it may be necessary to install a weaker spring. If during this tuning of your valve you are faced for example with the red spring being to strong and the blue spring to weak, you can add the spacers to the blue spring to increase the tension by small increments, thus achieving a setting between the red and blue springs.

Valve Spring color coding

Green - 5-15 PSI

Yellow - 15-23 PSI

Blue - 23-30 PSI

Red - 30 + PSI

The above figures are estimates only and should only be considered as a guideline

Please note - fitting a stronger spring into a valve will not increase boost pressure unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is to strong may cause damage to the turbocharger."

 

Yeah i read that. My friend thinks that i have the yellow spring in right now so we're gonna try to put the next best one in. I think that is the blue one. Im also going to get a j-valve on tuesday and see if maybe that helps. If all else fails im gonna get the vag test and figure out if there's something else wrong with the car. If you have any more adivice let me know. Thanks

 

isntad of spending money first, get your codes scanned, and then procede with buying what you actually need.

 

I will...I think my friend is going to do it for me. He has the program. But im gonna be able to test the j valve out before buying it so i figured i may as well do it since its free.
