no coolant leaks anywhere
no blown headgasket, checked oil, no white smoke, compression good
water pump was change less than a year ago and its not leaking
radiator was also changed to an aftermarket aluminum radiator less than a year ago
thought there was air bubbles so i bled the system but it was fine for a week and it overheated again
changed thermostat to nismo thermostat
radiator hoses were change to new ones
temperature sensor was changed but with a used one
radiator cap was changed but with a used one
also found out tonight when i was overheating again that my heater was blowing cold air when i turned it on
so any ideas on why im overheating?

faulty /wrong stat or air around the stat. the stat sits in water and opens at set temperature. if your rad was clogged , the water around stat might be cool. too(guessing) . run without the stat and see what happens.
first, though, park car on steep hill and run engine with rad cap off. shake the car by sitting on bumper. heater on.
You can change the thermostat without removing the fan etc but you need a small ratchet wrench with small extension to get the bottom bolt.
