I boosted my B20

ok I boosted it and started her up yesterday.

I would like to know how the vacum lines are placed
which ones are blocked and which ones are usable.
The car is also idling up and down

What are your thoughts?

What are your thoughts?

you should read the turbo guide.

let us know how that b20 holds up with boost. how many pounds are you boosting?

same here

i got 1990 integra gs 4 door with a b18b and it idles up and down im thinking about getting a b20 and boosting it and if i boosted it id run mayb 12 psi

The stock b series motors don’t like boost past 8-10psi.

^^^^

i would disagree with that, i dont know all the details but he had a b18a1, 17psi on stock internals… fully tuned of course with no short cuts

thas bs my couzin had a b16a comp cams rods PnP hondata ofcourse and a garret turbo in his 89 hatch and he ran 12 psi minimum and sumtimes he even ran up to 18 psi it was ridiculously fast the hole interior stripped those cars are amazing at everthing the track the strip you name it there so lightweight

With a tune, b20’s will handle boost fine up to 10lbs. From experience! anywho… i want pictures. Also is it the b or the z?

i wouldnt drive it untill you have it tuned. tow it to the dyno if possible.

search on here for the up and down idle is a common problem.
