Your right. The Y8 is 127 hp and the Z6 is 125 hp. The motor in the Del Sol S is a D15y7 (1.5L non vtec 102 bhp @ 5900 rpm, 98 lb-ft @ 5000 rpm). I believe the engine code is stamped on the block. Check to see if I am right. This pic is a new D17A2 from the Civic EX, 127 hp as well and 1.7L, but the intake manifold and the throttle body is the same "style" as what you are talking about right?
