So, i have mad extra parts laying around from friends swaps and such but i have a question or two about the bottom end. Just tryna to throw a little single slammer together.

I have a z6 block

Y8 pistons

Question is, is there a differance between z6 pistons and y8 pistons?

Basically just curious if it will raise the compression a bit or anything of that nature.

I have a fresh z6 head also to throw on that bottom end if it all fits together.

and wah-la! fresh and free single slammer for a future shell or something.

Any input will be greatly appreciated.

it will all fit. i believe the y8 was dif in the intake manifold and other outer parts. the y8 and z6 head was a tad dif but parts still fit each other. like a b16 and gsr head

the pistons will work but you will need y8 rings cuz they are diff from the z6 and it will lower your compression a tad but not enough to really notice it, but id spend the few extra bucks and buy dohc zc pistons cuz you can get them for not much more then just buying rings and you will have 12:1 compression and if tuned right it will tair *** and pull on all stock b16's and most gsr's. But its up to you...

just search for D series compression calculator on google. Or mill the heck out of the head and block. D series heads are cheap, I can't even sell a Z6 one for $50.

Just throw it all together and boost and spray it until it blows.

z6 pistons - Dome (cc) = -10.1; Comp Height (mm) - 30.00

y8 pistons - Done (cc) = -6.2; Comp Height (mm) - 29.3

thanks for the info fellas

most people use a z6 bottom end and a y8 head but the pistons will fit. do you plan on boosting?

i wasnt planning on boosting, i was just trying to put nother motor together just for fun, and to have really. Maybe find a shell to put it in or something, i also have d16a1 pistons laying around. from that dohc d series motor. any idea what the will do or if theyw ill fit? maybe a sweet high comp single cam is in the works. and if they do fit, what crank and rods/ bearings should i use? thanks again

Crossbreeder

actually, i have a full d16a1 motor.

i own a bone stock d15 which is currently the orig motor that came in my 94 dx coupe.....wondering what potential it has since im on a super budget build....any insight would be great.....IM NOT TRYING TO THREAD JACK....im just brand spankin new to ht and cannot start my own thread...thanx ahead of time

if you have a d16a1 then deff take the pistons out of it and put them in you sohc build. those are the same as zc pistons and will give you 12:1 compression. and if you tune it right it will rape b16's and most gsr's... ive bult a tone of those motors and i know im gonna get hated on cuz im talking about building a d16 but theres alot of power hidden in them if you know what your doing... you can build a d16z6 with about $1000-1500 and be over 200whp and b16's go for like 1500 and there 160hp at the crank. Just using those pistons and a header cold air intake and a good tune you will end up with 150whp and about 120wtq so its up to you but thats what id do...

And for the sohc haters i do build dohc vtec motors and own a few right now. I just like sohc motors cuz no one likes them so you can get the parts cheap and when you do beat a doch vtec motor with them the look on there face is price less lol...

can i use the a1 pistons with the a1 rods? or do i have to swap them too? thanks man.

i've seen some where that a y8 block n a zc head will bump compression

what? 75mm piston rings are 75mm piston rings. explain to me the difference. i'd like to hear this explanation. and i don't want hearsay, i want facts please. i'm not calling you out or anything, but that for some reason doesn't make any sense...

edit: just looked around a bit, and most places that sell rings for both engines have them listed as the same part number. why would you want to use rings that aren't made for the pistons if what you are saying is true? know what i mean?

or you can build it right ONCE and it wont blow.

Don't worry, he's just wrong so thinking about it too much will cause your head to implode.
