I recently bought a 99 civic ex. The previous owner spun a bearing and pulled the motor. I dont know whole story but i have a civic with complete y8 motor minus the short block.

After searching around it seems every y8 motor for sale has a spun bearing. I just wanna throw a block in it and call it a day. I read that a y7 block may work with the y8 head. Is this true? If it will work is there any other things i should know. Are there any other blocks that will work?

 

qft, lol
y7 and y5 bottom ends will work.
also you need your knock sensor from your y8

 

So if I pick up a y7 or y5 block all I need to swap over is the knock sensor? I assume I would just have to drill an tap out the hole on the new block. Will any y7 or y5 block work or are there differences from say a 1997 and a 1999 y7 or y5 block?

 

y7 should have the hole tapped for the ks.
obd2a\b blocks are the same.

 

Sweet. This makes finding a block a whole lot easier. Thank you.
