i want to bore out my d16y8 and i was wondering if i would be able to bore it out to where it would be 1.8 lieter??? or is that impossible. how far will i be able to bore it out ???? and if 1.8l is possible can i use itr pistons ????

 

You would have to sleeve it to 81mm. That would cost you more than buying a GSR long block.
