N13's had a 1.8lt Holden Camira engine didn't it? Not sure about the 1.6's though. My old man owns a 1994(Jap Made) N14 Pulsar Q with a GA16. I can confirm it is an EFI TWIN CAM 16valve 1.6lt , cross flow with Variable Timing Camshaft (VTC). Factory specs says
81kw@6000rpm, 147Nm @4000rpm. These engines were also used in N15 1.6's.
