Fittings on wastegate, bov, and turbo?

[Blizzard242]

Ok, I've got a general idea but what exactly are these fittings for and where am I gonna want to hook them up to? Yay for pictures.

#1
Wastegate


#2
BOV


#3
Turbo side 1


#4
Turbo side 2


Ok in #1 What are those fittings for indicated by the green arrows hah? You can't see the top one cause it's away from the camera. I'm geussing they have something to do with a controller and if they do, do I HAVE to hook them up to anything if I'm happy with the 9lb spring in it for now?

Also in #1 the red area. I'm assuming that's where the wastegate exhaust gases it releases goes to. Should I have that routed to my exhaust or would it be fine to leave that how it is?

Ok #2
The tube comming off of the BOV goes somewhere.. But I don't know where to put it. Help?

#3 The little fitting on the turbo in the center of the picture.. What's that used for?

#4
Before I hook them up backwards which fitting is the oil feed and which one drains?

I've been asking a lot of questions lately and I feel I've been really annoying.. But I'm comming close to assembly time and I've been buying tons of parts so I gotta know before I totally wreck something. Heh about 400 posts ago I didn't know what cylinder heads were.. or rockers.. or valves.. or anything besides what an airlid was and an exhaust pipe. Now here I am getting ready to almost overhaul my engine this next month for the better. Bought a whole car just because you guys made me feel completely capable of doing this myself. I never took an automotive class in my life and now I'm teaching my noobie friends. I just wanted to show my great appreciation and say thank you to everyone who's helped me learn all this. And hopefully will still help me. I almost wouldn't mind sportin a decal. Almost :-P I think I'll get one for under the hood if they're available. Thank you guys.

Someone help this man out! Sorry I haven't been online lately Dustin and I just got home from a 12 hour shift otherwise I'd try and chime in here, I'll try to tomrorow if I'm on.

Re: Fittings on wastegate, bov, and turbo?

Those fittings on the wastegate is to determine the pressure building up in the intake so the turbo can create boost or vaccum.

The whole that you are pointing at with a red arrow is for to release pressure so it can make a determained amount of boost, that mounts after the turbo.

The BOV I'm not sure where it goes so can't help you there.

The fitting on your turbo is used to determine boost when the boost gauge is hooked up to it.

And for the fittings on the turbo the one on your left (small) is the in line and the one on your right (big) is the return.

Ok, I have the wastegate figured out thanks to TurboV6's mspaint drawings :) The BOV though.. Where do I want that tube connected to?

Re: Fittings on wastegate, bov, and turbo?

green ones are vacuum and boost lines. the red is exhaust from when the wastegate opens you can recirculate this to the exhaust. it's your choice it makes it quieter. vacuum line on top of blow off valve goes to manifold vacuum and the fitting on the turbo is a boost source. The smell fitting is oil pressure side. make sure it has a oil restrictor in it. the turbo only takes like 4 lbs of pressure. the large fitting is for oil drain. i think that covers everything

Yeah I'm just gettin the details nailed out. I'm not doin the cam or messing with the heads this season. And oh man.. I gotta do somethin with that exhaust pipe that's been flattened. That thing sure is nasty lookin.

After thinking about it I came to the conclusion that the BOV needs a line to the manifold vacuum.. thank you for confirming it :) How to do that exactly I could use some help. Other than that, you pretty much cleared it all up. Thank you!

Re: Fittings on wastegate, bov, and turbo?

just find any vacuum line on ur manifold and T in it. I think I used the stock FPR vacuum line and T'd it into that. Been a while since i had my turbo Fbody.

Re: Fittings on wastegate, bov, and turbo?

Shane, thank you very much. I think I have this turbo setup completely figured out now. :burn:

Re: Fittings on wastegate, bov, and turbo?

glad to hear. speed safely.

PS. I wouldnt use that BOV though.....they are prone to leaking. And that wastegate is prone to boost creep but try it and watch your boost level and see if it creeps or not.

Re: Fittings on wastegate, bov, and turbo?

Oh man, thanks for worrying me more! Everything about this turbo kit I bought seemed great.. until it got here. everything for 1500 though.. I'm not sure if I can complain yet. And the wastegate being prone to boost creep.. does that mean It'll release pressure more than expected or is it gonna add more which would be something I really don't want. I just don't want to run lean and burn up my engine. Oh and for future reference which BOV and Wastegate brand or type would you recommend?

Boost creep is a condition of rising boost levels past what the predetermined level has been set at. Boost creep is caused by a fully opened wastegates not being able to flow enough exhaust to bypass the housing via the wastegates itself. For example, if your boost is set to 12psi, and you go into full boost, you will see a quick rise to 12 or 13psi, but as the rpm's increase, the boost levels also increase beyond what the boost controller or stock settings were. Boost creep is typically more pronounced at higher rpm's since there is more exhaust flow present for the wastegates to bypass.

Ive always used Tial wastegates and either Tial or HKS BOV's and have had no issues.

I'm one for peace of mind with my equipment and I have to change that whole ball flange where it's connected to anyways.. And I know you have a lot of experience with this so I trust what you say. If they aren't extremely expensive then I'll go ahead and get em while im at it.
Ahh jeese if I knew wtf I was looking for, I'm geussing a 38mm. Holy hell... For a first timer what kinda PSI should I be tryin to run? I have 42.5# injectors.. stock cam and stock heads just for this season and 1.7 rockers.
So can I just get like a .6 bar waste gate roughly rounding up thats 9psi where I started and just add a controller when I'm ready to up it? Is there a limit to how much a controller can increase a wastegates resistance? I'm asking a lot of questions sorry.

ur looking at like $600 in parts for Tial stuff...check ebay. On my V6 Fbody was runnin stock injectors and a bone stock motor with just an FMU on 9psi and ran great. Was runnin mid 12.5-12.60's all day at 108mph in my automatic. Id stick with 9-10psi for now till you get comfortable with it and then upgrade injectors ect.... There is a limit to a boost controller but you wont have to worry about that much boost ;)
