Anyone know where I could purchase a stock Mazda turbo 20b oil cooler.

Or, if the 93-95 REW oil cooler is the same size, or larger, and if it
would be an acceptable alternative to using a 20b unit?

Mark, I suspect that they might be using 2 of the '93-95 REW oil coolers
(365 hp). These are very efficient and strong units, however, new they are
about $400-500 from Mazda. You can buy used ones for under $100, just find
one that isn't beat up. I believe they've been the same size since the '86
turbo came out. They have good size fin openings and  pass a lot of air.
I'm planning on using one inside my wing for the 540. I wish I had used
this unit in the first place.

p.s. Maybe Leon, or others could comment on their reliability.
