You WILL NEED AN ENGINEERS CERT!! the mark up is not 25%. I am current running around with a rb25 that isnt yet ticked off with vic roads as they wont allow it without a cert. I have been to vicroads over 5 times, each time with more evidence that the r32 came out with a rb25. Last 2 times i went they even cought up on it being a rb25de that came with the r32.
vicroads people also wont care less if its got a high mount turbo as big as the engine or a stock turbo, thats not why that knock you back. The last chick who looked for the engine number wouldnt have known what a turbo was. i have a high mount and that hasnt been the problem. So far, everytime i have gone, they have somehow noticed the engine size step up when typing on their computers so a message must come up saying it needs an engineers cert.
sorry to put a down on your plans but seriously, its not easy getting it passed. im ganna try a few more times at a different vicroads in the hope someone just doesnt pick up on it. Might be easier for you being in W.A but in victoria, it seems im ganna have to fork out like 4G to get this all cleared over
