Run a compression test. Do you have the check coolant light? check your coolant overflow tank, If that is low fill it up, and if it drops back down you might have BHG.
Check out.

Check your oil also, if it is milky looking thats a sign of bhg cause coolant is mixing in with your oil.
Since there is a thread with this title I'll post here as well.
My car has begun to overheat on me but seems only when the boost is used. I'm using factory stock psi and never modified it with a MBC or anything.
I had the factory hg changed over a year and a half ago but it was for yet another factory hg replacement. I changed the thermostat and fan clutch with new ones. The water pump is fine and I have no leaks of anti freeze, the back up tank is also full. When I start the car it has white smoke like the OP said but I figured like him, it was the cold weather. I also checked my oil but it doesn't seem milky, a solid black color, no white residue.
I really don't want to accept its a broken head gasket although I'm starting to tell myself it is and my current one will give out any day now. Is there ANY other possibility or something I overlooked that can be causing my sudden overheats during long driving and sudden boosting? I take the precaution and grandpa drive my car now to prevent any damage to my engine since my supra is also my daily, but the needle seems just a LITTLE above normal towards the hot side and it bugs me a bit.
Thanks in advanced.

Could be low on coolant. Have you ever had a radiator flush? might be a good idea considering its a 20ish year old car.
If you start it and blast the heat is it warm or cool? Check the coolant overflow tank, sometimes that gets low and would cause you to have no heat.

If your oil is solid black, you should change oil. It shouldnt be that dark. If there is coolant in your oil, you'll see it when you drain your oil. And the same when you drain your coolant, you will see oil floating on top.
Another thing you could check is if the airflow to the radiator might be blocked with leaves. When i installed a new radiator, the old one was clogged up with leaves and feathers. i had no idea until i removed it from the car... check that out

Yeah this week is my scheduled oil change week. (Tomorrow to be exact) I will look at the drained oil to see if there is coolant mixed but I didn't see any oil when the coolant was drained before we installed the fan clutch. so I'm assuming the head gasket is still working but it's worn and about to break if I was to put the car on the highway constantly with extended boost.
As for the leaves in the radiator, never thought of that, although its worth a look, hardly any trees in new york though lol. Thanks for the tip!

Oil color is a very poor indicator of when it needs to be changed

Draining it to determine if there is coolant present with other BHG indications = good idea.
