JDM model had 147kw. Your probably thinking of the JDM DC5R (162kw).

Other differences between JDM and 98 Spec AUSDM:
Rear sway bar (JDM 23mm, yellow stripe)
4-1 header with 2.5" collector
shorter cat, longer cat-back
16" wheels

There's probably more than that but thats all I can think of off the top of my head.
