here is a good converter for you guys with jdm cars :
http://www.convertcenter.com/unit.aspx/ ... n/km-litre
some good input and some not, got 9km/l on the meet up north... find that REAL good! around town i get 6,4km/l to 7,4 km/l.. my problem is that I like the sound and drive to hear it... found that the race cats (berk) seem to give me better fuel economy. I wouldn't buy this car if I had to think about fuel costs. then again 1500€ road tax didn't put me off either
Have you ever driven a non standard z with aftermarket exhaust,cats intake? if not DO! any cost issue goes when I turn the key
