Buy a spring based on your idle vac reading




I bought this valve to replace my ebay HKS SSQV which was wonky. This valve has been great and car feels smoother then ever.

The Good:

• Very smooth on and off throttle, no fuss
• Looks pretty cool and was cheap
• Should support pretty much any boost level you can throw at it
• Adapter fits great and not leaks with the o-rings "don't forget to lube them a bit"

The Bad:

• This thing is massive especially with the added height of the adapter , make sure you have room
• It's very quiet , this may be a good for some but I like my rice sounds
• Edges are sharp and it is not as nice as the OG tial as far as machine quality goes

Install Tips:

• Open the valve up and clean it, these things are mass produced and not quality checked. Make sure you check it all over and clean out any metal shavings
• Install the spring you need or don't idk I am not your mom LIVE YOUR LIFE
• Lube the shaft "he he" with silicone paste , it comes pre-lubed but you need to clean it so service it at the same time.
• Use an 8mm Vac Line to the Intake Manifold "I have read that people have the best success with such a large valve doing this, no vac blocks"

Conclusion:

I am very happy with this valve. I have been hooning around for a few days now and it works great. Car is much smoother in and out of throttle and just wants to go. Boost builds smoother as well. I have not had any surge issues.
