i'd say take it to the dyno, let them do it while tune it to the best too
but in the end of the day, you'd wanna get more mods before doing that kinda thing, it's not something you take your car to...
dude, my mate found one in japan for NZ$4k, if you want it, i can get more info off him
but now i haven't got that much....even if my mum leaves nz and sells her car, she still would've give me that...
it just doesn't apply to engine mods.
like EuroAccord13 said:
if the fault of the part/accessory that needs to be replaced is not directly related to the modification/s or found not to be caused...
well..i'd say if you got enough, you should put a K20A in it instead of finding another jazz/fit engine. we got a few for sale here in new zealand on nzhondas.com...
