i have a d15b, and i was wondering what will i need to do to the block to make it work in an obd2 car and not have any problems... the issue that i am having is the d16y7 in my car has bad oil rings so it needs a rebuild.. i have a spare d16y7 head so i was going to bolt it on to the d15 and throw it in while i rebuild the y7. i was also going to use all of the obd 2 head components. i just wanted to know if there is anything that i need to do to the block to get it to be fully compatable.
