zc aftermarket pistons and rods

[Lurker]

Alright, im a honda noob. I use to drive a SVT focus before I got my crx. I now have a crx with a dohc zc and want to know what type of aftermarket pistons and rods can I buy to boost the motor over the 200hp mark. I will be having it tuned on chrome and I know the stock internals are only good for like 8-10lbs and 200hp. Help out a ford converted to honda noob.

endyne pistons are good

or JE pistons+Eagle rods

with the proper ECU management / head work you can reach 300hp+

I have spent about 30 hours in the last 4 days searching for the same info

That set up would work, you would need to get some dish displacment numbers and Piston-to-Deck Height specs, then use this site :

to figure out what comp ratio you would get with the different options they offer.
I have not tried this only because I'm broke and not planning on going over 160-180 HP
I might be ordering the pistions.

Ill be using suzuki vitara pistons and eagle h-beam rods for about 18 psi/300+hp. Any 1.6 d series internals pretty much works......

nnooooooo you REALLY dont want to use those pistons. Because of the ZC head volume, the compression will be like ~7:1. You could run almost 30psi of boost on pump gas...but i dont think you really want to do that. To get 300whp using those pistons you would have to push 26-27psi+ of boost because of the compression.

Im a big supporter of compression. Honda heads are designed to work with higher compression, we can get away with it without as much detination. So why fight it ya know?

And for that same reason, you cant just drop in any old 1.6litre piston. The deck height is also different on the ZC. You want to get a piston that is made specificly for the ZC. A 9.5:1 compression piston for a d16Z6 will get you 8.2:1 compress on a ZC motor.

With all that in mind, do your shopping correctly. Wiseco makes ZC spec pistons as does Endyn (which is also a Wiseco piston made to Endyn specs).

I personally have 9:1 compression Wiseco pistons in my ZC. They have a very small dome and arnt dished.

Wesico 9:1 compression ZC pistons




Now imagine the compression using the Vitara pistons - checkout that DISH! Yay for ~7:1 compression!
