    Exclamation Z20let over fueling????? How many mpg????

    Hi i have recently done a z20let conversion with vxr turbo, vxr acuator, lower mount intercooler, tx autosport tophat . . .

    The problem is that I have put in over £100 in a week and have barely done over 200miles its averaging out at £10 for 20miles is this something that is common with these engines? Fuel price is 126.9

    Can anyone help??????

    That's not right mate. Mine has a few mods and i have a heavy foot at times. I average 33/34 mpg on a run and 26 round town. I get about 100 miles for 20 quid.

    Well as most people will say, it depends on how you drive. However i think even with a lead foot you could possibly get more miles to your money than that.

    Mine is the same as the above. Can do slightly better if im super super careful of how i drive, otherwise i generally budget £20 for 100 miles

    Boost leak/ vacuum leak. I was gettin 17mpg and I found it to be a slight boost leak at around 12psi when I pressure tested it but wouldn't leak until that pressure. When u did the conversion did u use zlet lambda sensors etc?

    Yeah, around £20 for 100 miles for me too. 35ish mpg long runs, 30ish round town, sometimes less.
