I've seen a few cars this color but never a CRX.

I was running 10psi on the Z6 but the boost didn't have that much to do with the rod knock. I just ran it at to high of a RPM for to long(long rear ration DX transmission) and stretched the rod bolts. Plus the motor had a good amount of miles on it too.(not sure how many but in a year and a half I put on 9000 miles.)
