At the end of my turbo build and im looking for a picture or two of where i need to tap my, Wastegate, Blow off valve, and Boost gauge into... what vac lines? doesnt it matter... can i tap them all on the same vac line?

please people that know what there talking about only.. and Picture or two of where you tapped yours in helps ALOT.

 

Wrong forum.

 

i'll take a pic of mine tom and then post it

 

thanks depsy.

 

the BOV and boost gauge can be tapped in the same line as the FPR. The waste gate vacuum goes to the nipple on the turbo.

What I did was tee my boost gauge with the FPR and tee my BOV with the "U" looking vacuum on the intake manifold. If you look at yours you'll see what I'm talking about, it's literally a "U" haha.

I did that because when I had everything running off the same vacuum, the BOV was not getting enough vacuum so it wasn't working properly. Now that I switched it to a more strong vacuum source it works fine and you can hear the difference.

 

Yea A few pics would be extreamly helpful. I have been wondering about that for a few months actually!

 

i dont have a nipple on my turbo.. lol and the wastegate is suppose to have a vacume source. so im assuming just about any will do.

my t3 has 5 parts to it.. oil feed/oil return/intake side/charge pipe side/exhaust.. theres nothing else.. lol nope no nipple

sorry i just thought the comment was funny.

 

idk then, thats how my EWG is connected to my t-28

 

The wastegate just needs a source on the pressurized side of the turbo. Typically turbos will have a nipple right on the turbo to provide a source for the wastegate. On the stock Evo turbo there actually isn't a nipple on the turbo. The nipple is located on the J-pipe that connects the turbo to the intercooler piping.

 

ok.. so back to my question..
can i use ANY vacume line?
and can i tap them all into the same vac line?

mostly what i wanted to know.. figured i woudl jsut use what ever line that worked just fine for everyone else..
(oh, its a Tial wg, greddy rs bov, and a glowshift boost gauge, cuz i know it matters a little bit)

 

damn forgot about it, give me a few min i'll do it now and hope it helps

 

yes you can use any vacuum hose.
or you can use high quality colored silicone vacuum hoses, like from hosetechniques.

 

ok i think your a little off on the question.. i ment can i use any vac line on the car, not any type of hose... i mean could i use the brake booster? lol.. i mean its a vac line.. has the best all around pressure/vac responce.. lol.. because depending on where the vacume line goes into the IM it will all be a little different.. and can i tag all 3 of them into the same vacume line? or would that mess them up a little bit..

ill just do what depsy did, but i am planning on trying to do a good wire tuck in a few weeks, (jsut soemthing free that will allow me to work on my car for a while)


o.. Tial 38mm WG.. side is for vac line? and top is for boost controller? (i think)... and im not using a boost controller'riht now' so i just leave the top not hooked to anything... right... (or is it the other way around)

 

a few pics:

 

oh okay haha. yes you can tap the brake booster, i was going to use that for my BOV.

For the WG, use the side vacuum line. If you use a boost controller, it would go on the side too. The boost controller will tee in between the side vacuum of the wastegate --> intake manifold vacuum source (whichever you decide to use)

Looks like depsy tee'd the same vacuum line on the intake manifold too.
