    anyone running a e30 m20b25 and..

    ...can tell me what kinda oil temps they are seeing in what environment? I had my m20b25 powered '02 at the track today, it was about 34celcius outside, after 7 or 8 laps (around 1:15 laptimes) I had the oil temps approaching 240degrees. I'm not sure what is 'normal' for these engines or what is considered scary territory. But previous to this I had not tracked the car with this engine, and had only gotten it to about 185degrees on the street. Normal temps seem to be around 170. I do NOT have the oil cooler installed, otherwise it would not have gotten that hot. Using Mobil1 15w50 if you are interested.. I was hauling some major [Oops!] though :)


    thx

    WElll..

    Okay, the whole story is that the m20 is in my '72 02/m20. Combine the added time to put it in, plus the added room needed, plus the inability to figure out exactly what threads are on the filter mount housing so I can convert to -AN and put a Mocal or Setrab unit in there....well....I just took the entire think off and ran without a cooler.

    Back to figuring out what kinda fitting it needs I guess :)

    thx

    I've seen it as high as 260F near the end of a 25-minute session at the track where the air temp was in the 100-105F range.
