On the weighbridge it came back at 970kgs, the rear seats alone weigh 40kg, air con weighs 30kg. This is the 2nd highely modded one in the country the other one is 300bhp as featured in the redline magazine. The 2nd fastest is 270bhp but hes just wacked the boost up and put a scooby turbo on it, the graphs i have were from when it was remapped which shows the stats.
Also the ECUs on these are a pain in the ass to deal with, i put a different exhaust on it and it kept cutting out, if u map it for more than 200bhp your going to get problems, this has had an ECUTEK ecu and remap at the cost of £580! which a lot of lads in austraila and japan are using. The standard turbo is rated to 250bhp this is why i never run it on high boost just 1bar all the time.
As for fuel i am getting 45+mpg my car computer and the scangauge 2 i have both read the same readings. A lot of people with the standard czt are getting 60mpg on motorway running.
