Go buy a Mugen N1 K20a - cheaper than a JDM k20a in Australia

$7K if you want one....

There's about 40 differences between the AUDM and JDM models...... very different cars - and I have had the JDM DC5R race car sid by side with a local DC5R, and its like chalk and cheese..... everything is difference...

You can buy "track ready" DC5 ITRs in japan - ie - no stereo, etc....
