Sorry to be a thread snather, but just one question..
Is there any difference in which rr ratio you choose to use?
Ie. Are certain ratios designed for certain engine combos?
Does one provide more power?

Cheers mate!

I would rather the 200kw engine, as i wouldn't do that many mods. only exhaust etc. insurance is cool with new engine so may as well put the more powerful one in. how much would i expect to pay for one of these?

200 wasnt n option on the au utes, only 185. sedan xr8s for au went 185, then 200, then 220, but the 220 are a little harder to track down
