I just pulled out my D16z6 from my 90 hb because it was getting piston slack or something, i had 3 pistons with bad compresion. Now my question, i have a good D15B2 botom end in my garage. Im wondering if i can still get some decent power out of that D15b2 botom end with the d16z6 head. I just had the head sent out to the shop, to get resurface with new valve guide and 3 angle vavle job.I heard that you get higher comp ratio with this setup. Im runing all PM3 ecu,dis, and intake. I just want to know if anyone ever did a setup like this and got decent power out of it.
