im lazy :) lol but im currently holding in my hand as im typing with one hand, a 32mm adapter. and im about to install it in the next hour, so ill let u kno how it goes

radiator
 

hey i have 88 supra do i need the fan for the radiator or can i get a radiator without fan because fan is so loud

Yes u need a fan it will over heat without it. If it loud then the fan clutch might be bad and is not releasing or u can switch to electric fans.

whats better electric or just leave it as is i also think there a air leak in exhaust bc engine noise over powers exhaust

If your fan is that loud the fan clutch fluid may be emulsified. Inspect the fan clutch. As for replacements, my preference is for lightweight, aluminum flex fans... They're mechanical, as quiet as electric (quieter than some electrics) and more reliable as they don't depend on additional sensors, relays and fuses. With modern mechanical vs electric fans, when pushing the same amount of air, the mechanical will probably be quieter as there's no additional motors driving it... It all depends on the design of the fan blades.
