Tomorrow i'm going to leave my car at the shop to have my sensor bungs welded in to the header, and while they are at it, they are going to throw on either the Greddy Type-RS or HKS SS blow off valve. Any reccomendations? I have the 6psi pully non-after cooled.

I'll post pics of the install and if I can get my hands on a recording device, i'll let you guys hear the sound!

 

You know my thoughts, but I doubt there is going to be much sound from 6psi.

 

The HKS would be the loudest..and with only 6 psi. that would be the route. I steer away from them with high boost as they sacrafice bleeding ability in exchange for alot of noise but it would probably be perfect for you. If memory serves the greddy sounds like a turkey on acid anyway

 

HKS. I have one on my S and had one on my RX7. It sounds great. Gets heads looking . It was louder on my RX7, not only because it was turbo but because I was running 15lbs. ! HKS all the ways. Also looks good IMO.

 

About the loudness, I have the godzilla on mine and at 4,000rpms its LOUD and sounds like the Greddy type S.

 

d'oh! I went with the type-rs and I cant even hear it! It's blowing off a lot of air, but its doing it quite silently. Does anyone know if the HKS SS uses the same mounting bracket as the greddy? I might have them swap it out. Or if anyone here has a greddy type-s they'd like to trade i'm open to that. I had the type-s on all of my other turbo cars and love it. Why did they discontinue it?!

 

hks and greddy type s use different types of mounts.

d'oh! well there goes that idea....looks like I have to source a greddy type-s. any takers?

 

i would take it if it was the type S.

 

i have the greddy type s (purple top) just sitting in my garage. i'm using the hks on my s2000. it was used on one of my turbo integras. let me know if you want it. i'll take any reasonable offer.
