boost gauge

[leesredgt]

noob question which line do i tap into to plumb my boost gauge in pics anyone?

Find an unused (or T into one) vacuum port preferably one after the throttle body (most accurate signal there) in the intake tract. Some people will say in an I/C pipe, but the most acurate as to what the engine sees is after the T/B

A boost/vaccum gauge needs full manifold vaccum. On the rb20, there is a nipple right below the brake booster connection. That's what I used.
