JDM engine

[Supra2NR]

well even if he did take off the egr himself
see how the block-off plate looks like

if it sits perfectly to the manifold it might be a jdm engine
or it could jus be a jdm intake manifold used with the motor

but check the plates anyways, they might give you a clue if its a jdm motor

and the pipe on the heater core
it the driver-side is blocked off and the opening is on the passenger side
its a jdm motor
