Am I wrong in saying that without a thermostat, your coolant isnt spending enough time in the radiator getting cooled? If your system is just running an open loop, the hot coolant from your engine is running straight through the radiator and right back into the engine, without letting the radiator do its job. I know you said youve tried multiple thermostats, but have they all been the same? Possibly a lower temp one could help you out.

Whoa back up here.
First off, how far up does the temp gauge get that it may (or may not) be overheating?
You're car has been touched at some point. You should have a dual fan setup stock. Not a single.
Thermostats are placed in cars for a specific reason, they're not just there for kicks and giggles. I understand you've replaced it several times with no results, but you NEED it. We'll get back to that later.
What have you tried replacing so far?
I would suggest doing a full flush on the entire cooling system as a start. It would cost may be $50 to do yourself and a hour and a half of your time. A flush and fill is not hard to do yourself and is a good starting point on problems like this.
Other things to look at:
Are you losing coolant? If yes, then you need to find out where it's going.
Do you have a proper mix of coolant? 50/50 is most common but you can 70/30 (Coolant/Water) and still be okay. How old is the coolant?
Has the radiator cap itself been replaced? Cooling systems are put under pressure (usually 13-18 psi) to increase the boiling point of the coolant. If the radiator cap is not doing it's job it could cause over heating.
It is possible that the gauge itself is malfunctioning. Our gauges are not that accurate in stock form.
Lets work through this and narrow things down before too much money is put into this. There are other things I probably forgot to mention, but it's morning and I'll remember at some point.
