I have a JRSC. At first i loved it, but had some problems with it. The Blower itself is now off my integra, and is being inspected. The blower itself was leaking oil, and gave me a boost spike and a lack of power. But other than that i like it very much. If i had to do it again....maybe turbo. But more boost is always great. I was very impressed with the kit and the sound alone the zzzzzzzzzzz is great very intimidating. Can't wait to have it back and boost 8.5psi. The ONLY BIG problem is you can't boost past 11psi. If this is an issue go turbo.
