Okay heres a thought to throw around...if the D15z isn't a great performance motor, I believe it was a mpg king in its day. The D15z had higher compression than th B7, but smaller valves. So, in theory, could'nt you just swab a B7 head for more power? I know you would lose vtec...or even a Z6 or Y8 head?
