i have the type R. i have no compressor surge. i adjusted it so it opens at as little as 1psi

I only get a tiny bit of surge when I make like 2 psi and then let off. Its because the spring is designed to hold higher boost. It isn't a problem though. Order it through me so I make commission. Faster than ordering it through the site as well. I only see the universal listed. That means it needs to welded into the intorcooler piping. The car specific ones are usually for stock turbos and come with an adaptor piece.

Ok cool, i'll order straight from you then. I haven't gotten a chance to play with the spring and hose on the apexi bov, so give me a couple days. Welding to the pipe is no biggie, thats how I have the apexi on there anyhow.

mmmmmm, compressor surge

Well i fixed the surge after playing with that spring. There is a very slight amount, but barely noticable now. Silver: i'm gona have my friend get that bov from you anyways here in the near future.
