vac diagram question175556

[nissans13240sx]

ok i am trying to do the vac lines on my car this week and i have a few questions about the diaghram i have... if any one can tell me what these objects are that i have circled are? i think C is on the intercooler but im not sure about A or B. PLease help me out.

One is the boost solenoid and one is the boost pressure sensor I believe. As far as I kno you don't absolutly need either of them....well @ least I don't have them on my swap

[S14Life]

i didnt use a or b and c is the stock recirc valve on the sidemount.

If you are not using the charcoal cannister or any stock emissions crap how would the diagram be then? Also using MBC and BOV and FMIC. Can anyone recreate that diagram with my setup? It would be greatly appreciated.

[nissans13240sx]

2-4-0 is it possible to send me pics of how you have urs setup? or anyone in that matter, i need pics of how you eliminated boost solinoid and pressure sensors.

Here you go. This is how I have set it up on a few SR20DET installs.

[nissans13240sx]

ok i think i did everyone a favor here(that is if i did it right). PLEASE CORRECT ME IF IM WRONG! i think i did it right

[nissans13240sx]

Here you go. This is how I have set it up on a few SR20DET installs.

it should go intercooler nipple -> boost controller -> then wastegate not T off to both of them.

[nissans13240sx]

so u have the boost gauge hooked up to the tb vacuum going to the fuel pressure regulator? Bov gets its own line. thanks for all the help guys

I don't think so. If you do that it will cut all boost going to actuator, whereas my setup leaks boost so the actuator reads less than the actual boost.

OK if the MBC does NOT come with bleeder hole use this setup If the MBC does have a built in bleeder hole use this setup

[oki_bum]

sorry to bring up an old thread, but if you MBC has a bleeder hole, do you REALLY need to tap into your IC coldpipe? I cant just plug it in someplace else or even just plug it up? I really dont want to have to tap it in to the cold pipe then jb weld it and wait another freakin day before i can drive my car, cuz i've had to JB weld something for the past 2 days now...

[oki_bum]

anyone?

[ILikeMy240sx]

for the quickest boost response from your boost controller, you want it closest to the turbo possible. This is not absolutely crucial but is the best. You will have less boost spikes.

You can pretty much hook it up anywhere there is pressure.

thanks, i ended up just drilling the coldpipe and put in a brass fitting from autozone. So the line from the BOV to the wastegate should be as short as possible?
