what's the largest oil filter that will fit a 4ac?

[stantheman]

stock is a Z158 as per RYCO naming scheme.

I was wondering would a Z131a fit?

seal diameter goes from 63mm to 70mm.
z131a is longer, it has more filter surface area and hence it will be less ristrictive.

or am I just out of my mind?

The filter on top is for S13SR. S13SR filter fits 4A oil block. The big filter is screwed to S13SR oil block.

???!

There's probably bigger filters off tractors or whatever that fit and have similar enough bypass valve operation too.
