B18 vs. B20 breather box. 120-130

Keep in mind that a B20 oil breather box does not fit into a B18. One of the few differences I discovered when I dropped a B20E into my 220.

It requires some creative hosing and the use of the B20 PCV valve (which screws into the manifold) - does work very well though... I did not know it made such a positive improvement in tunning ability or that it runs in reverse...

I figure you guys know about that, but others reading this post in a "vacuum" might not know the installation implications...
