Hey Mate,

Welcome to ozlib!

Try using the search function on the site to find HEAP of info on conversions.

Lots of the members on this site have done the conversion or similar conversions to what your looking at doing - Myself included. I converted my 1998 gen 2 heritage with a 2001 GT-B...

The most common conversions seem to be gen 2's converted to early wrx, v3 sti or legacy gtb. Obviously the halfcut /engine combo you decide on will be determined by your budget

Here are a few threads to get you started:
