How about a 4AGE corolla, they are stronger than a swift, and there should be more parts available. There are also a couple of guys running them in the clubman series to share parts and knowledge with.

Or a S13 Silvia, they are cheap, have heaps of power for a 2wd, heaps of performance parts available cheap. Although you will chew through the rear tyres.

N14 Pulsar SR20 could be a good thing maybe..

An X3 Excel could be an option, there is heaps of knowledge about them at www.excelrally.com.au and plenty of parts around. They seem pretty strong, and if rallying isn't for you then there are some guys trying to get a race series started up, which should be a good laugh.
