imo there is a big difference but if your gonna boost they will end up in the same range all motor route out of the box the dohc zc will work the a6

agreed. It depends on what you are looking for. If it was me I would save $500 and get an a6 and boost it. But if you just want to stay all motor, drop in a motor, and not do anything else then get the zc cause it will be more fun with the extra 22 hp.

The a6 is a great engine, and so is the ZC.. I think it would really depend on what you can get a a6 for. if its more than 200 dollars cheaper.. ----, go for the a6.

Re: dohc zc or usdm spec a6

yup...like Jeff said..
ZC is overated IMO...I have three ZC's in my shed and one in my car...on of them is blown thought..rod thru the block(low oil leak) and one has a spun bearing(low oil pressure) the other one is fine.
There rod's are the same as the A6 rod's. They will take as much. the old brown top ZC's have thicker rod's though from the front and the side it's thicker. I just rebuild a D16A9(euro ZC) with ZC1(browntop rod's and pistons) lower comp domed pistons..comp is now at about 9.1:1 and I used a D16A6 crank cause it's orginial crank was damaged by a spun bearing...
