Confirm my setup(awesome drawing)

[hpmachine]

I just finished recirculating my bov. I'm happy with the results so far. Can you guys just check out the way I've got my vacuum lines plumbed? Any input would be appreciated. Oh and enjoy my sweet drawing skills LOL

[hpmachine]

C'mon! 50 peeps check this out, and I get no input? Is the drawing that bad?! ROFL

[ceno]

yes

Ok 1st off your avitar rocks. 2nd im stoned and all i saw was nipple all over that drawing sorry, but hey I'll give you a free bump.

[IanS]

switch the nipple you have feeding the pressure side of the bov with the nipple you have feeding the MBC, you want a boost source as close to the turbo as possible for the wastegate, it would shorten the amount of line you are using and it would be the right way to do things. Hopefully that maid cents cause that is my .02

[hpmachine]

Awesome guys! LOL!!!

[adrianfromthecastle]

LOL nice drawing...

why not bov on cold pipe closer to the tb?

[IanS]

cause he already has a nipple on the hot pipe right by the bov, but near the tb would be best

[driftking91]

Are these directions to get somewhere?

[corey240]

would i benefit recicing my bov? i have hks bov

[hpmachine]

driftking91 - Yes, they are directions to the land of happy afr's and stable idles

corey240 - Every setup is different. I've heard that the hks bov does not cause some of the problems associated with other bovs. My greddy type-r was giving me grief, specifically when I backed off the gas and coasted in gear. I would run waaaay rich. Recirculating helped that alot.

[doridori23]

Noone needs a recirc bov but if you are using an L_Jetro fuel system (you have a maf) then having your bov recirc will prevent rich spikes, possible stalling(buy a new bov!), etc etc. If your still using a maf and you are looking to up the power instead of getting a 300z, Ford cobra, ford lightning, etc etc maf just get a real fuel computer and eliminate the maf. Nissans with ford parts are wrong on many levels.

Actually where your wrote to BOV after hot pipe is technically BEFORE BOV due to the direction of the airflow.

Otherwise it looks good to me.

Also I don't want to run a recirculation bov when I get my SR, can I cure that with an E-MANAGE?

[hpmachine]

ok here is a revised drawing as per your advice. the compressor is now feeding the mbc and the hot pipe is feeding the pressure nipple on the bov. Sound ok? thanks again!

you can cure that with just a safc.

poyfect, nook nook nook

[hpmachine]

Awesome. This forum is the only reason my car is still alive. Love it.

[240 GTR]

i dont have a boost controller, so the line from the wastegate and compressor should be connected?

[hpmachine]

I think so. cuz i'm pretty sure all the mbc does is 'fool' the wastegate.

[240 GTR]

alright. i'll give it a shot.

[IanS]

You are correct sir

[240 GTR]

well, slight problem. i dont have a nipple on the compressor or the hotpipe. coming out of the wastegate is 1 line with a T at the end. where do those lines go?

[IanS]

you should not need a T, the wastegate needs to see a direct boost source( no vacuum), if it is a S13 motor you can use the nipple on the cold pipe side of the bottom of the throttle body, normaly though you want it to be as close to the compressor as possible, like on the hotpipe or compressor housing.

It doesn't matter if the wastegate sees vacuum, as long as it sees boost.On my SR20DE+T, I had my wastegate running to the dedicated line below my throttle body (plenum source), and my water injection switch and bypass valve (Greddy Type-RS knock-off with recirc adapter) were teed off the FPR line.

Now I have the wastegate getting it's source directly from the compressor (I've drilled and tapped it for a 1/8" NPT hose barb), the water injection switch is teed from the FPR, and the bypass valve on the dedicated line.

The difference is the total boost that is made, I peek about 2PSI lower than I did with the previous setup, the reason being, is that the pressure source at the plenum is post intercooler, so if the pressure source is from there, it'll compensate for any pressure drop caused by the intercooler.

The way I have it now, it's just cleaner. There's a lot less number of vacuum lines running around now.

Many wastegate actuators dont like vacuum, they tend to fail prematurely, plus having it that far from the turbo reduces response time.

[240 GTR]

so running the wastegate line to the bottom nipple on the TB is ok? i have a redtop, and none of my IC pipes have a nipple on them for a vacuum line(except IACV). also, there is a vacuum line coming off of the intake inlet pipe. where does that go?
