what are the options?

 

The SE oil cooler and rad setup are the best for the FB's.Unless you want to retro fit a FC rad in the bay.If my GT-X wasn't running a T2 motor and FMIC I would run a racing rad for a FC and make the brackets at work on my spare time.SE rads keep the first gens with swap even cool enough so it should work on whatever plans you have for the car.

 

yeah stock gsl-se aftermarket radiators work fine

 

Best option is (like said above) to get a new stock SE radiator.

 

this is for a T2 engine in an SE body
