It's a 94 hatch with a fully built darton sleeves lsvtec turbo and I have a 170'f tstat in it and on the free way it runs around 200-205'f I have a dual core radiator and running 50/50 antifrezze. I have the fan coming on at 180.. Is there any thing i can do to keep the car about 190 steady

 

dual core radiator but what kind of fan setup?
sounds like an airflow issue if it's getting hot while driving.
check make sure your radiator isn't blocked or air in the system.

also where you located because 50/50 isn't always great on built cars more like a 80/20 water/coolant or 70/30..

 

I live in Ohio and I'll try the 80 20 but I do have a huge intercooler blocking the radiator well most of it and it's just an eBay special

 

So you think I should run 80/20 what's wrong with 50-50??

 

well theres your problem with the intercooler
