Overheating problem

[JDM240SXcoupe]

I know i have searched and tried but still overheats! Ok so here is the deal I have a 1992 240sx coupe with an s14 engine. when i turn it on and let it idle for a few mins the temp needle is right at the middle.It wont overhead when its just parked. Once i take it out for a drive it starts to overhead.Sometimes it will also oveheat when i push it hard. I have replaced my radiator with a brand new mishimoto radiator.I replaced the thermostat too with new one from oreilly. The water pump is new thats what the previous owner said. And the fan works but i thought the fan clutch wasn't working so i installed 2 12in slim(electric) fans.And still overheats. I have tried to bleed the bubbles by raising the car from the front. Squeezing the hoses.And still have the problem.I have no idea on what else to check/do/replace.I'm thinking of removing my thermostat and run it like that for a day and see if it would still overheat.Any help will be appreciated.

have you thought about head gasket issues? Take your radiator cap off, turn on your car, and see if bubbles are coming out at any kind of consistent rate.

Hmm Well i havent notice any bubbles ill check that out but i dont think so.How can i test if its bad?Also my antifreezer install milky so im guessing is not bad.I checked my oil too and its not milky.
