For those wanting to put a FWD 4a-ge (bigport OR smallport) into their RWD corolla or other car, here is a quick guide to fixing the water oulets.
# Maintain the original FWD water pump and associated pipes etc. If you bought the motor from an importer or the like, remove the water pump and replace it (recommended highly).
# Take a remote thermostat housing (complete) from an AE82 4A-C (run down to your local self serve wreckers, cost $10)
# Get yourself the flat type rear water outlet on the back of the head (i got mine from an AE82 bigport 4age)**pictured below**

# Get yourself a handful of hose clamps (new) and random bits of radiator and heater hose from the wreckers.
# Cut the rear outlet of the waterpump (big pipe) around 3-4inches from behind the waterpump
# Do the same with the smaller outlet from the back of the top radiator inlet at the front of the motor
# Use a small straightish section of the smaller diameter pipe you just cut to use as an extension piece to connect two heater hoses together
# Put together as you see in the pictures below
