2jz na-t vaccum?

[tomsupra8683]

I recently did a 2jzge na-t swap into my celica and im only getting -10lbs vaccum at idle is this normal?I could only find a couple boost leaks and they were small it was just some of the vaccum plugs i used.My 7mgte always had -20 under vaccum so i though the 2jz would have the same.

What cams are you running, and what sort of elevation are you at? Given that your old engine created more vacuum, I would think that you may have a leak somewhere...

Something is either leaking or not hooked up. Should see around 17-20 in hg

Im at sea level.Its a stock 2jzge out of a 96 lexus is300.I must have more leaks ill keep searching.The metal gaskets for the intake maybe the issue i didnt replace them cause they looked good.
