you will never get 130bhp and good mpg from one, the standard inlet manifold is balls so needs to be first to go, to get the 130 mark then your going to need a custom inlet/itb's, cams and standalone management.
yeah MPG is a real killer.
but 130bhp was pretty easy to obtain tbh
with a working ecu and a decent map the k4m engine has plenty to give.
i have high lift cams in mine and its pulls all the way to 8k. feels like it has more in it![]()
I have a 1.6 16v and read on here (I think) that they weigh about 1300kg
