Joe,

    Early on, Lou Ross send me an A/C core with AN fittings for use as an
Oil cooler.  I never tried it, seeing as how I figured the oil had more
viscosity than water, my concern was  about the small cross channels in the
core and whether it would handle the flow.  I did try one of Earl's oil
coolers and was unsuccessful, but to be fair, it could have been the
location (12" from Firewall), but my (and others) success with the stock oil
cooler make it hard to beat.


The 93RX-7 and later, has two smaller oil coolers that might be more
amenable to your physical space constraints.  I never had one, so don't know
their dimensions, but you might check it out.
