hi i thought i might add a bit of info on my sr20de.
im from austalia and i recently had my motor swapped as the old one died.
the head code is 53j and under that it says 2R.
according to the list mine should have Normal pistons, highport, egrless and gold/black Valve cover.
Yet my car has the egr system still fitted i was told that my standard inlet manifold was used with the jdm therefore retaining the egr setup or some say that it might just be a plain oz spec motor and your lists just confused me a bit lol.
heres some pics
thanks
