well would you like to post what block you have and your setup? 87-89 teg pistons are the same as the ZC. Use the calc to find your CR and next time use the search option. :)

sorry about that, I was ina hurry to post. I have a D16Z6 that I am going to use stock rods with and at first I was going to use D16A6 pistons but then I found out that I can get the 87-89 integra pistons for a cheaper price. I heard that they produce a high c/r similar to the ZC.

will the D16A6 headgasket work well with the D16Z6, I used the c/r comp thing and it dropped it down to about 13:1 and thats right around where I want to be at.

the gasket should work however you might want to double check to be safe. I hope its a nonstreetable motor or you can get 104octane where you are. Thats a mean CR to be running 91 or 92octane.

yeah, it is a really mean c/r to use for streets. its not going to be a daily driver but its going to but driven more or less on the weekends and sometimes on the track. luckly i can get 104 octane kinda near my house. do you know how I can check to findout if it will work.

i thought that the 86-87 a1's were the pg6b's with a dome of like 1.5cc's if i am correct. even with the jdm or 88-89 a1's with a dome of 7.4cc's would yeild 11.6.
