can someone check my vacuum lines??

[Team_Undisputed]

so i was wondering if anyone could look over my vacuum lines and see if their correct

heres the pics:line 1: starts at the left nipple on top of the throttle body

and ends at the nipple under the FPR

line 2: starts at the right nipple at the top of the throttle body

and ends at the nipple on the BOV

line 3: starts at the only hole at the bottom of the throttle body

then goes on and T's off

the line that looks like its going down in the pic up top goes to the nipple on the intake

and the other line goes to the top of the actucator

thats all i hope everything is correct thanks for looking guys! (sorry for the bad pics)

anyone??? please

[positron1]

I want to know this too.

Check it out fellas, I run a Greddy type RS bov atmospheric. Here's my set up. It bogs sometimes but I think I have a bad bov. But everyone said my set up was good so here it is hope this helps!

thanks man but it looks like you got a boost controller and your BOV is on the opposite side of mine i wonder if that makes a diffrence??

Not sure about the intake because mine doesn't have a spot for a vacuum line but the wastegate is more efficient if it runs off the hot pipe, as close to the turbo as possible. Besides that, looks fine.

alright thats good but but my hot pipe doesnt have a spot for a vacuum line do you have a pic of one?? plz im trying to get my car squared away by saturday( first drift event) hahah

That shouldn't be a problem. FRsport sells nipples with tightening hardware. They're $10. They told me to drill a hole in my coupler attached to the hotpipe, then insert the nipple through the inside of the coupler and finally, tighten the bolt from the outside to keep it in place. If you don't see it on their site, try calling. I went to their store today and they had 'em in stock. Hope that helps.

BTW, 200RX has the correct vacuum setup in case you needed confirmation.

[200RX]

This is a Greddy IC kit my brother got, it came with the bung already in the hot pipe. Try calling some local machine shops and see if you can get one put in.

Here's a close up, I teflon taped it up hardcore. The nipple I got at Home Depot, I'm sure any hardware store would have one.

Nacho_240 also has a sick idea. May cost less his way, good job Nacho

Are you sure thats right? How is your boost controller NOT hooked up to your wastegate? It should be. you should have an OUT line going to your wastegate and an IN line going to your controller. without that I don't know how your system could be working.

You may bog because your BOV is atmospheric, (lying to the MAF about how much air is in the system) If you recirculate(a tube running from the BOV to the intake system after the MAF) then you should be able to kep that from happening and it usually improves the response from your turbo and fuel economy.

BTW nice work on the pic

it should not matter where your BOV is located. Some people say it responds a little faster if it is on the coldpipe(closer to the intake mani), but I don't know if thats true, and I have always had mine near the turbo/hotpipe side. This is the first SR that I am going to run a recirculated system on so it being on the hotpipe helps with that. I really want to have it on the other side because it will help clean up my engine bay.

[jaco]

yea and no boost gauge in that setup? anyway.....i have the bov on the cold side because you let off throttle .....bov releases every thing in the entire charge pipe? it seems to me that just off the tb is the spot that can clear all the boost out efficiantly. or did i forget to eat my common sensios this morning ?

[200RX]

Hey Nzmoman, could you by any chance put up a pic of your set up?

[positron1]

Speaking of boost gauges, where do you run the vac line coming from the boost gauge to in a setup like this?

[nzmoman]

as soon as I get a digicam I will do that...You wont really see much...Im ashamed at the mess. do you want me to create something perhaps? I have an S14 SR so my throttle body is not the same.

Boost gauge on mine is t-d off of my FPR

nice set up man, the main reason i want to get that wleded on is because i took my car to get inspected by the SR guru here in town and he took off my boost solenoid and switched up my vacuum lines and ever since then my turbo has been really loud (screechy) laggy it used to kick in at 2700 and now it kicks in until 3500 and ive checked for a leak and i found that it was missing two bolts and i put those on and the screeching got lower but the turbo is still laggy so can this be a wastgate vacuum line problem??

and i was also wondering if i could hook up my wastegate line into my intake line since its close to the turbo and all.

I'm not sure about the situation with the turbo ,but yes you can hook your wastegate to a nipple on your hotpipe. The closer to the turbo you can get the better.

Off the FPR.

As for the hose barb, here's what I did, sorry I don't have a pic, never took on but its simple. I just drilled a hole slightly smaller then the threaded part on my hose barb and I ran a tap with the same dimensions as the barb into the piece I drilled. After that I took some JB Weld and put it on the threads of the barb and threaded it in. Allowed it try for a day and it was SOLID. I've had no issues so far. Just go to the hardware store and get a barb that'll fit your vacuum hose nice and tight.

did you use pipe a pipe thread tap to make the hole?

[duffman1278]

I don't think I did but I'm not sure because I know for a fact that I have pipe taps lying around my garage.

This thread is awesome! Very informative. Although it's older, I'm bumping it because after searching many of the other vacuum line threads I received more info from this ONE than most others combined! Thanks contributers to this thread!

i believe the only ports on the tb that are actually vacuum ports are the top 2. the port at the bottom of the tb is not a vacuum port.

if you take the tb off you'll notice the ports on top are actually coming directly from the intake manifold.

easiest solution is to run it like so:

Small port on top of tb to fprLarge port on top of tb to bov. You can also t that line to go to the waste gate. If you have a boost gauge; t it again for that.

The oem setup uses the hot pipe (actually cold pipe) for vacuum because the waste gate sees less vacuum from there. You boost slightly lower but more consistently.

Getting vacuum from the hot pipe also gives you slightly "faster" waste gate response.
