Hello all, done some research so I have that it can, and cannot be done.

Smoking oil badly so I know I need new rings, so I might as well get new pistons as well.

Z6 head with B7 block. Will ZC pistons work with that setup. Everything is stock, and i will keep the rods from the B7.

Also with the ZC change compression or will I not notice a thing..

zc pistons are domed. so your compression will definately go up. but im not sure if it'll work or not

TravisCadello

ya it will. compression will raise a lot!

alx_90ef

just do it!!!

jawsiiv

So not to be dense, yes as in they will work, or YA JUST DO IT FOR THE HELL OF IT? LOL

i hadthiss etup in my crx a b7 block dohc zc pistons and a 2 layer y8 gasket made it a13:1

alx_90ef

god dammit that pretty high.

jawsiiv

So are we talking about major detonation, can I just swap em in, or is there anything I need to do to keep my car from exploding and handling that compression

101 octane?

i heard this topic before some where go check it on google search around i'm sure it will work but it's better to double check. Check this crx http://www.youtube.com/watch?v=QHqRVqPQD-8

yeah go for it and yes it will work but those pistons with those rods wont get all the way to tdc

the pistons are stamped PM7 on the top...and they are the highest domed piston you can get from OE. i ran them in my y8 until the vtec solenoid froze open starving the block of oil and i melted them....i've been trying to locate some but to no avail. if anyone knows where i can locate some (minus junk yards, no decent yards up here) i would appreciate it....but back on topic, my CR was 12.5 to 1 and it ran like a raped ape. go for it and let us know how it turns out.

jawsiiv

so the with D15 rods will running these pistons work? if they can't get TDC will something be destroyed.??/

medorihb

i ran the rods that came with the pistons and a y8 head, never had any problems, some slight pinging at about 6500, (running 94 octane, highest i could find) but no internal problems, no piston slap or anything of that sort. you should be ok.

Thanks for the info

if you go with ZC pistons you HAVE to get it tuned...

i had a z6 that i put 75.5mm zc pistons in. it had a "gas knock" (detonation). get some bigger injectors and get er tuned.

jawsiiv

The pistons I am getting are 75.00 would it matter?

jawsiiv

bump

medorihb

they will drop in with no problem.

fryguy190

you will be fine. 75mm is stock bore size for ur block. i had bored mine and put oversized pistons in mine. it dosnt make that much of a difference
