Ive got an ISIS screamer elbow forsale. It was used for literally 20 minutes of driving. It was installed just so I could test a new o2 sensor (the KA o2 screws right into this elbow but the SR20 elbow needs an adaptor for the KA o2). This elbow can be used on an SR20 or KA turbo setup. it comes with both gaskets. I paid $110 plus shipping and duties for it. Got it from enjukuracing.com. Save some time and money… $50
