I was just wondering if a JRSC from a d16z6 would fit on a d16a6? I'm guessing it would bolt up fine, but what about firewall clearance, belts, and others. Anyone know?

 

While the blower itself will be the same, intake manifold bolt holes may be different, water passages may be different, belt sizes and pulley placement may be different. I'd suggest calling JR on this one, they probably know fairly well what will and won't work together.
