so i bought a civic ex and the engine runs a little rough. not bad though could get a quite a bit of use out of it im sure. it came with a b7. only gerts about 22mpg....

my question is. should i spend the 150ish or however many dollars on plugs/wires/rotor/cap/filters and possibly 02 sensors

or just fork out the addition 250ish and just get a whole new z6 swap?

i would like to swap eventually but the thing is if i do this tune up and that doesnt fix my mileage problem im gonna be realllllly upset.


any thoughts comments are appreciated.

i would just get the z6 swap...that b7 motor is too weak to pull the weight of the ex body which is y ur getin shitty gas mileage

Y did ur ex come with a z6? And instead u could put a z6 or y8 head on it. As that's cheaper and will make about the same power (a little more if it's a y8). But it will have higher cr so forget boost.
