i can guarantee you compression tested it wrong. More than likely its from like you said the throttle not being all the way open or from the engine not being warmed up. I would just stick with the z6 you have now. Not worth swapping for a y8. Also its been said that the z6 head at higher power levels will always outflow the y8.

I had a y8 and spun a rod bearing on piston #4. The stock oil pumps SUCK and should be changed out. My motor was stock, oil changed every 3000 miles with a Honda Oil Filter. Never ran hard. At 90,000 miles it took a turd and all belts and everything where up to date. Spun a rod bearing on one of the hottest days during the summer.
