Need opinios d15b7 vs d15z1 vs d16z6 swap battle

I have couple questions before I make up my mind indefinitely. If I rebuild the z6, how much mpg improvement would I see? Two mpg or three? Or would I stay at around the same? Keep in mind that motor blew at over 200k miles getting 37-40 mpg.

Dont expect mileage in a simple rebuild. Unless your engine was running very unhealthy. And that 200k doesnt mean anything if you can return all clearances back to spec.

What do you mean the motor "blew"? That tells me a rod went flying through the cylinder wall, a bad rod bearing, etc. Lost compression is usually what happens to old motors as the piston rings and cylinder walls deteriorate. If your motor was suffering from compression problems you will notice a nice improvement.

I only had 40 PSI compression in one of my cylinders before replacing the motor with a refurbished unit. I went from 32 MPG to 38 MPG after the new motor.
