I just picked up a hydrolocked D16Z6 out of a EG. I plan on rebuilding the motor. But I wanted to make this a NA motor. What would be the best pistons to use? Crank.. etc.. This is going to be a motor Iam myself will try to rebuild. And as far as the head what sorta vavletrain needs to be used? The motor is going into on of my crx hfs. IS this motor a obd1 ?
