I have a crx d16a6 engine 95% done. it was completed but didnt run right. I am told i need a new block. One cylinder has rust pits. so i guess it would be cheaper to buy a used d16 block. My question is what d-series blocks can i use without changing comprsession. A6 blocks are hard to come by being 15 years old. any help?

 

sohc zc non vtec blocks plenty of them and are cheap
