November 22, 2010 - Here's the new radiator along with the old one.
The size difference is even more dramatic in person. The fan shroud is a really nice piece, it's laser-cut aluminum built specifically for this radiator. The fans are two fairly high-flow SPAL units with high-torque motors to help them pull against a restriction like multiple heat exchangers. Not a problem here, but most "low profile" fans will fall off dramatically even when asked to deal with just a single radiator.
The rad itself is the same basic design as the other one, but with a more efficient core. Based on testing at Flyin' Miata, it should actually outperform the big guy.
This is all off-the-shelf stuff designed for LS-powered Miatas by Flyin' Miata.
