hey ive searched and I cant really find the difference inbetween the d16a6 and z6 blocks.
i have a 91 hatch and i was just wondering if i could run a d16z6 block with an a6 head.
sorry i know it seems kinda backwords but my a6 block is sorta shot and i have a new a6 head and my friend just gave me his z6 block

 

Would you consider trading the A6 head for a Z6 head and converting your car to OBD1?

 

Hi i also researched this, due to me having a bad z6 block i wanted to keep my z6 head so i got a a6 block, from all i learned the blocks are the same, the a6 has a restrictor where oil flows to the vtec in th ehead but other then that they are the same, all i had to do was remove the restrictor and now my head doesnt even know there is a different block under it
