I recently installed a bigger turbo (ct 60 trim) and I have been experiencing overheating problems which I never had before with the stock turbo. After driving around for 20-30 minutes, the engine bay gets extremely hot, especially being here in Florida. However, the temp gauge is dead in the middle, the fan is working, the water pump is fine, and there is plenty of coolant. It is running pretty lean because of the turbo and the timing is definitely off, so could that be the reason it is overheating? Or should I bleed the cooling system in case there is any air in there? Thanks

It smells like an overheating engine and the engine bay is a lot hotter than usual. I cant even touch the radiator for a split second even after the car is turned off for 15 minutes

Anything else changed? Missing heat shields, etc? Other mods? What boost level?

Smells like overheating usually means a coolant leak. Not being able to touch the radiator is normal.

Lower temp t-stat won't do anything except delay warmup. It doesn't increase your reserve cooling capacity.
If you've got a laser thermometer you can check and see what the upper rad hose is, it's typically within 5*F of the coolant temp. Otherwise I'd hook up an aftermarket temp gauge and find out exactly what temps it's running. I know that the stock gauge will read in the middle as high as 225*F. I can't find it at the moment but someone actually mapped out a graph showing the angle of deflection on the stock gauge vs. the actual temps and there was a huge spot that was near flat in the middle of the gauge for a wide range of temps.
The stock electric fans beside the clutch fan on the radiator comes on right around 210*F, are they constantly on? If not, you're at least staying below that temp.
Also, as others have already pointed out, bigger turbo = more heat. Your temps really could be fine but you're definitely going to be getting more heat in the engine bay from the turbo alone. This is going to make it heat soak more at idle and for the first bit while sitting. Make sure all of the underbody panels and your fan shroud are in place and that your clutch works on your fan, they help a ton with the cooling system efficiency.
