Hi New To This Web Site And New To Wrx's,just Wondering What Kpa Is In Relation To Lbs On Boost Gauge And What My Stock 04 Wrx Manual Trans Should Be. Thanks Joep3

I'm not really sure what a kpa is :eek7:

.1 mpa = 14.7 psi

1 BAR = 14.7 psi

I think a kpa is .001 mpa, so 14.7 psi = 100 kpa

in which case you should boost around 100 kpa in 3rd-5th gear.

It appears I was mostly right, except it's 14.5 instead of 14.7 in all the numbers.

Thank You Very Much For The Info Greatly Appreciated.and Actually My Gauge Is In Mpa I Don't Know Where I Came Up W/kpa.
