i have both a 99 civic y8 bottom end an an 94 civic Z6 bottom end . i want to build one up with rods, pistons ,etc for my 96 hatch..is one better than the other?

 

bottom end?? hmm I don't think so

 

Neither one would have an advantage over the other..

maybe the y8 since the crankshaft would probably have less miles? but thats it.

just wondered, thought id ask before i started to tear one of them apart..i thought i heard something about the z6 having a stronger bearing brace or something. but at the y8 would be a direct swap.

 

IF the Y8 would be easier to drop in, I say go with that. What's the point of making more work for yourself? Especially for minimal or no difference.

 

I heard the Z6 had the strongest factory D Bottom-end.

 

use the 99 bottom end, using a lower year motor than your car specs is against the law in the u.s, useful info so you dont get your car impounded

 

No, the z6 bottom end isnt stronger

 

Who's going to impound your car for having an older engine? You talking about at smog checks or something? I sure am glad I live in a small town and don't have to worry about all that crap.

Since your planning on building the motor either one would work well.

 

So, is the Y8 and Z6 equally strong or what ? If so, I'd say the Y8 B/c a knock sensor is a great tuning tool if it can be monitored.
