Default 02' WRX Overheating issue+more FIX or SWAP?

So the check engine light came on shortly after I bought my wrx about 8 months ago for misfire cylender 3 and 4 although I never noticed a misfire. Then she started overheating after driving for about 20min then one day it got worse and would only take a few min. Yesterday I did the waterpump, thermostat, timing belt, ac belt and power stearing belt. Now its back to overheating after 20min of driving. So.. im guessing the headgaskets need to ne done. The piston rings, intake/exhaust gaskets, cam seals, and head studs would be done at the same time. This will cost around a grand because I will need to pay a friend to help. I also have a connect on a motor w/5k on rebuild w/ receips that has a bad cam for a $1000. My current motor has 135k and it also needs a new turbo and upipe. Which route would u go?

How would I check for that? I flushed it out real well when I did the waterpump and all that. And then whenI filled the system back up I made sure to burp it the correct way.

Highly doubt it's the headgaskets if it was over heating from that there would be tons of white smoke coming out your exhaust and oil all over your motor bay. Sounds like it needs burped properly I agree.

Engine cold > parked on slight incline, nose up > open upper reservoir > climate control to hot/fan off > start engine > add coolant until the level stays full, but before the fans kick on and hot fluid starts gushing out the top

Try "burping" your radiator. Open the turbo coolant housing and have the car idle and then pinch the radiator hose to get any air out. Because I did that today and it worked. I also had a f*cked up radiator hose and I got a new one and had to run coolant through the whole engine again so I burped it to get the air bubbles out then I was back to normal.

I had to replace the upper radiator hose on my 05 9-2x today as it got sliced by the belt and was spraying coolant. I replaced the hose and the car was almost overheating just driving it a few miles. I didn't "burp" it as described on this thread, but I'm going to as soon as the engine cools down. So just opening the radiator looking cap (turbo reservoir?) up by the air box and pinch the hose while running. Any other tips? Should that fix my problem?

I forgot to mention when I removed the upper radiator hose there wasn't any coolant in it. Is this normal? Looking at the reservoir it appears I didn't lose any coolant in the process, even when the slice in the hose was spraying coolant all over the engine bay.

I just went through the burping process, and the turbo reservoir was empty. Kept filling it and it kept bubbling and took 3/4 a gallon. Poured the rest in the radiator. It took the rest easy. Going to get more coolant in the am. Is it weird that the plastic reservoir is still on the full line?

I had the same issue with mine. I had low coolant but my plastic reservoir tank was still full. Burping the system does wonders. If you burped the system and get all the air out and it still overheats, then start looking elsewhere. Burping the system and making sure the HVAC is on hot, I put in about 2 gallons of water/coolant mix.

^yea it took me like 15 or 20mins to make sure my radiator was air free after changing my timing belt. The system uses soo much coolant. I'm assuming your radiator isn't stock? The '02s can only be filled at the reservoir infront of the turbo

Bulletproof coolant fill: Park on a slight incline, nose up; heater control to hot, fan off; open cold reservoir, start engine, begin adding coolant; you're full when the bubbling stops. No burping needed, but you can squeeze the upper coolant hose to move things along faster if you prefer.
