The ZC... the D15 block is one of the weakest blocks out there. It isn't the D15 block from your HF, right? If so, that one has 8 valve reliefs in the pistons, so you would need to work from the bare block. If you wanted to go with a NA D, I would use a D16A6 block because it has the steel crank girdle instead of aluminum.

The ZC isn't technically a D-series because it has a different engine code. The parts for D-series cars should (and correct me if I'm wrong) work in a ZC. I know that you can bolt a ZC up to an Si tranny, and I know that people have used ZC pistons in an a6, so it makes sense that it should all interchange.

A ZC block is the same as any other D series block, until the head. You can put an 1.6L internals into it.. infact the rebuild kit I used was from an 89 SI. Where it differes is that the head from a ZC or D16A1 will not bolt to a non ZC block, nor will an A6 head bolt to the ZC bottom. Because its twin cam, the oil ports had to be moved a bit, so it will bolt on, but the oil ports wont match up. You could line up the ports, but then a couple of the head bolt don't work.

If you are gonna spend alot of money, I suggest you research the amount of available parts for the ZC and the A6 that would make it a worth wild build. And then factor the cost of everything and just see how much it would cost to go B series. It's a worth wild upgrade if you are planning on sinking money into the car.

I think I would also go with the zc, I think you will have better luck with it. As stated, why exactly are you wanting to rev to 9k for?
If the engine is rebuilt properly, and the parts are there (rod bolts, head studs, cams, spring/retainers and it's tuned) I say push her to 9000rpm all you want. Why not. If the engine is BUILT for it you might aswell bring it there.

Who puts awesome springs/retainers and cams to not utilize them?

I still say you should look into it tho. Last time I checked DOHC ZC performance cams where hard to come by, but that was over a year ago and I didn't look to hard after I found a smoking deal on a SOHC ZC. Infact, I thre my knocking DOHC ZC in the garbage lol.

ok cool guys..... thanks for all the replys.

and i want to take it to 9k just because isnt it true if you dont have to shift as much and the oponet. you can win more races because you are staying in the high rpms longer than the other person would.... and i just thinking that way because my ZC dont start pulling real hard until around 4500 to 5k. so i have to shift right now about 75-8k sooo i dont know any body have any better advice...

and the motor in my car now i just built it like 3 weeks ago and its still running good
