I Need Some Help Please!!!!!
 

i am looking for a place that sells the HKS SSBV blow off valve for my 88 turbo Z. and is that the only company that makes them for the z31's. im not sure on how it sounds so if anyone can help me out that would be great. thanks

Well, the only company that makes HKS BOVs is HKS. That is the company's name, so someone else selling HKS BOVs would be doing trademark infringement and subject to all applicable fines and such.

I suggest you find out what a BOV is and what it does first. BOVs are not made for specific cars.

In any case, you can use any old search engine ( I like http://www.dogpile.com ) to find a place or places that sell HKS BOVs.

I'm also seriously hoping this is for a turbo charged car.
