Modify a KOYO
I currently run a single pass KOYO rad with a large Isuzu IC , my oil and water temps are great , especially on the highway , however they tend to rise a bit (95-98 deg C) when I'm in trafic for a while or when I stomp on it in short back to back bursts . I am soon going to be installing a Miezere 55gpm electric water pump (and maybe a thicker 4" intercooler) to keep temps under control , I'm also thinking about putting in two baffles (one in each tank) to convert my rad to a tripple pass , has anyone done anything like this ? , is it possible to do this without damaging the rad ?, anyone have any results to share ?

I have a double pass radiator that I bought from summit racing for $185. It works excellent. In the NY heat in traffic on a 100deg day, I see temps no higher than 210 F with the AC on. I've been using these radiators for the past 6 years with no issues. It's also half the size of the normal koyo or fluidyne. You should have no issues but I would rather stick with the wider double pass than skinnier tripple passes.

If I am to keep the stock radiator with the top inlet and bottom outlet (on a 3 RD gen ) , cross flow design it would have to be a 3 pass , If I was to do the 2 pass mod , both in and out would have to be on the same side .

Copy and paste from my other reply.
I just purchased a triple pass custom radiator instead of possibly butchering my Koyo. After I sold the Koyo and paid for my new hugh triple pass radiator I still had some money left over!
However I do believe it would be possible to modify your existing radiator. I decided not to chance it.
Koyo also maker a triple pass radiator called the N-Flow.
