Blew my motor first track day in early 2021. Built my own motor but ran into issues and needed to be pulled. Decided to throw in used complete engine for now from 2020 car with 18k miles. First track day in over 2 years. Very rusty but towards end of the day started to feel more comfortable. Motor ran great. ambient temp was 79F with sunshine. CSF triple radiator, no ac condenser paired with mishimoto racing thermostat. I could not get over 200F coolant temp in any of the sessions. I was so surprised. Oil was topping off at around 250F. Heres my best time. 1:14.06
