hey thanks for all the useful info. yeah i had a feeling that the stock oil cooler doesn't do too much. it's kind of worrying when i go to the track and it's in the 90's (degrees) and we're doing 5 twenty min sessions in vtec. i guess first things first. i got to install some kind of oil temp gauge to see if i am indeed exceeding 270 degrees and then decide if i need one. don't you guys think that at the race track (not dragstrip) that it would be fairly easy to go past 270 degrees when it's over 90 degrees outside? i'm just guessing.
