"I should also mention that I have a PA30 with serial number 909 with the turbo mod"
i will assume you have the IO320B1A engines, with the rayjay turbonormalizers. if that is the case, you need the Harrison oil coolers with (IIRC) 9 blades. the stock oil coolers (7 blades?) will provide insufficient cooling.
here's what i ordered a few years back from Pacific Oil Coolers:
#8529245 Harrison 9 blade is their #800 0074
the 800 0215 has 13 rows, a few rayjay installs have this cooler...
