Ignition advance unit?

[Civvy]

Does anyone know why my B20 has 2 vacuum pipes coming from it?
I've gone and bust off one of the pipes (3rd one!!!!) do we need them both??

well i'd think so man. for it to work properly dont you think i needs them all? they didnt just put another line for nothing.

haha, best thing to do is go get one off a junk yard or get it form someone on here. i think part stores sell them also, sometimes.

Why'd you do that, lol
Read the shop manual and see if you can leave out one of them somehow. The vacuum advance is the same on your B20A1 as on the A20 but both of the engines is covered in the shop manual, just be sure to download all of the .pdf files. http://www.pauldesign.ru/honda/shopmanual.html

yeah, ure not gonna want one of them from a parts store, i work at advance auto and just the vacuum advance unit is 93 sum bucks, jethith christ, haha, and pray u never need a distributor unless u have 300 bucks laying around, i sware, if junkyards didn't exist, neither would my car

Just get 88-91 Prelude distributor and convert that car to the PK2 ECU :P

Best thing you can do at the moment hehe.

the reason you need to vacuum lines is because one is working when the car is cold and the other is working when the car is warm.
