Swapping in a ej22t into my 86 Brat. The engine did not come with a radiator. Can anyone recommend one? Preferably aluminum?

Grab a tape measure and measure out your dimensions.  Find a catalog of radiators and find one that matches your dimensions and has the inlet and outlet in the right place.

For my N/A EJ22 86 BRAT swap, I used the 1st gen legacy radiator that came with the engine. It fits without needing to cut anything, you just need to fab a couple of simple brackets to mount it. I used four little rectangles of 1/4" aluminum, with one end of the rectangle bolted to the car and the other end bolted to the radiator, on all 4 corners of the radiator. The stock EJ22 hoses worked with a little length cut off the ends, and I used a 10" Flex-a-lite fan in a 'pusher' configuration. It's a pretty simple setup and seems to provide plenty of cooling. This photo is a mock-fit using zip-ties (you can see one near the bottom) before I made the brackets.
