OK, I have a DOHC ZC engine waiting for some pistons and rods. I have a chance to get any D-Series piston and rod set (STOCK) for 50.00! What rods and pistons will give my ZC the highest compression? Im goin N/A so i need high compression.

Try the 88-89 Integra D16A3 pistons. Although without any other work the ZC pistons will still have a higher compression.

d16a3? i thought it was a1? And how much will the CR rasie?

Milano_EH3

The A1 is the 86-87 'teg. The A3 is the 88-89 'teg. Well, I don't have an exact CR for you, but considering the similarity in the motors it won't go over the ZC's stock 9.6:1 without any other engine work.

so basically, if i dont have to change the rods and pistons i shouldnt?
