Stock clutch fan. It just has to be mounted on the oposite side of the clutch and shaved slightly to clear the damper. When i upgraded to a koyo performance radiator, i had to modify the radiator bottom brackets to make them shorter to move the radiator closer to the condenser. That and elongating the screw holes on the upper radiator brackets gave me just enough clearance (less than .25" on the upper tank) for the fan to clear. Motor only mover side to side so any clearance should be gtg.
I wouldnt recommend removing the oil warmer. I do believe it also helps maintain the oil temps down.
I'll share some pix later.
Only picture I have atm
