The easiest way I can think of is this http://www.pms.net.au/03_enginekits.htm#Litre25

Granted it is not the most cost effective, but it may be the easiest.

the EJ25D dohc will bolt right in, use your sensors if any of the plugs are different. the 2.2 computer will run it, just not at the optimal level.
