- LS distributer fit b21
- b16 pistons
- h23 piston rods

- Radiator/Cooling fan upgrade Replacing Radiator Fan??
- (It's worth noting that the fans only have an effect at low road speeds. At speeds >10-15mph the vehicles movement through the air forces more air through the radiator then the fans ever will. It's also worth noting that despite some of the info in the thread, copper/brass radiators are substantially more efficient then aluminum ones)
