Hey familyman... your post got deleted by mistake due to the generally
fcuked up state of the boards at the moment. Try posting a response to this

Hey guys, I'm a Toyota and AE86 noob. I'm installing a 2nd gen 4AGE in my 85' coupe. I've modified the coolant "manifold" to move the vacuum bung off the block side and changed the outlet for the heater core. Does this look correct?
Thanks in advance!

the RWD setup has the upper waterneck and the water pump backing plate connected via a "bypass tube". how do you have that bypassed so there circulation while the thermostat is closed? maybe the dashpot is hiding the connection, I see a tube from the upper neck(which isn't the rwd one)

Yeah, it's connected back there with a silicone hose...
Otherwise looks good, yeah?

Better picture of the whole setup.
