i just got a 91 crx si with turbo with a b16a engine. it has its at -20 vac on the boost gauge. my question is if this is normal or if it has to much vacum at idle.. i dont see ne cracks on the the trubo to the intercooler or from the intercooler to the intakemanifold.. so i dont think im loosing pressure.. if ne one can help me plz post.. thx.

 

your golden man. between 18-22 is a "normal" amount of vaccum. The major of replies are going to be within that range with most being 20". I myself am at 20" at idle. No need to worry at all.
