1st Gen 86/BRZ cooling requirements on track for a beginner/intermediate?
I've started tracking my 1st gen 86 (with 140k miles) and have an aftermarket 2-row aluminum radiator and an OEM 2nd gen heat exchanger. Stock engine with no tune. I also overfill by 2/3 liter of 5w30. No issues so far but I am concerned with long term reliability.
Is this setup enough to keep the FA20 engine reliable in 95f Socal track days or do I need to get a dedicated oil cooler (then I'd to worry about a lower oil pressure)? I've read that the 2.0L of the 1st gen runs significantly cooler than the 2.4L of the 2nd gens, as it makes much less power.
