Aussie GT4s do have EGR.

Not sure about 205s.

205 JAP motor will not have it. like all 3sgte jap motors..

Please dont bother trying to remove it if its for a "PERFORMANCE" gain.

it doesnt use exhaust gas unless you are at cruising speeds. full throttle ZERO diff. unless its not working properly.

Hope that helps :)

Removing it wont give any immediate performance gains, but it might in the long term.
EGR makes a mess of the intake manifold and throttle body. Leaves all the insides coated in carbon.

Removing it also simplifies the engine bay a little.
