im putting a stock b16a2 into my 89 si.

does anyone have a vacuum diagram for this particular motor? i printed out the diagram I found on this site but its different than my motor.

its all converted to obd1 with obd1 injectors no resistor box. im just tryin to have no vacuum leaks when I fire her up.

its in the faq but the pics are down, perhaps you can make sense of it through the posts...

 

I cant really make sense of it. I tried to make use of the diagram from the faqs but it is different than my set up. maby I need to draw something up on paint and post it. I cant because im at work but I will see what I can do

 

Post a picture of your manifold...

 

im at work let me see what I can find

no one?

I have the charcoal canister and purge solenoid on the fire wall. whats the proper way to hook them all up?

 

someone else asked for this in the EFSS thread..and i quote

 

FYI: your intake manifold is from an OBD2 ’99 up Si. You are going to need to add in an Air Temp Sensor along with you vacuum situation…

I'm working on your diagram.

 

yes I extended the IAT temp wiring. I have holes drilled in my cold air from some jackass using nitrous so I taped it in place until my stock intake box gets here.

thanks for the help man, I really appreciate it

That diagram a couple posts up is the best example your going to get. Just follow that and plug up the extra nipple on top of the manifold.

 

i have a 1990 crx hf and the wires for the map sensor are different in the si the hf has like two connectors the thing is that they cut my wires and now i dont know which ones go to the map sensor any help?
