OK OK...I did use the good ole search button, but this is a pretty broad request and I get ALOT of unrelated threads....
I have a regular, run of the mill SR20DET swapped into my '89 240sx. I recently swapped in a larger aluminum radiator with dual electric fans and shroud. I also removed the OEM clutch fan.
I have noticed that even at freeway speeds (60-70mph) the water temp is creeping higher than it used to with the OEM SR20 radiator and clutch fan...I have actually had to turn my fans on while driving on the freeway in low 60's weather.
I'm sure my aftermarket FMIC is blocking alot of the flow to the radiator...

What have yall done to your S13's to improve airflow to the radiator and lower running temps?

Would an air diversion panel really do anything noticeable?

Short o cutting holes on my front bumper.......
