Turbo setup done- no boost? *WITH PIX NOW*
 

Ok hooked everything up finally and put a turbo basemap on my integra b18b LS and still not getting any boost read on my boost gauge. Any idea guys? I need to double check for leaks but everything seems fine. Hooked up wastegate to turbo compressor housing. Its a tial 38mm wastegate, used the side port. Helpppppppppp =P

Re: Turbo setup done- no boost?
 

Do you hear the turbo spool? Feel anything? check for leaks. Close wastegate and do a gut check.

Re: Turbo setup done- no boost?
 

where is the boost gauge connected to?

Re: Turbo setup done- no boost?
 

Listen for the turbo spooling. If you don't hear it... that's your problem.

If you hear AND don't feel it, you have a boost leak.
If you hear it and feel it, your gauge/source is screwed up.

Does your guage read vacuum or does it always say 0?

Re: Turbo setup done- no boost?
 

pics?

Re: Turbo setup done- no boost?
 

Ill try and get pics, update right now is ive tried two gauges and when im flooring it itll go like 2 lbs of psi boost maps. All vacuum lines look good i dont see why im only getting like 2lbs of boost. not using a boost controller. 38mm tial wastegate 8psi spring

I hear turbo spooling, bov goes off so must be some pressure

Re: Turbo setup done- no boost?
 

are you sure you put the fire ring in,

Re: Turbo setup done- no boost?
 

What turbo are you using?? take some pics, you are probably just overlooking something simple.

Re: Turbo setup done- no boost?
 

after saying that all i can say is boost leak bad!! make a boost leak tester and go over it, im sure thats your answer

Re: Turbo setup done- no boost?
 

is vtec enabled?

Loose nut behind the wheel....

Re: Turbo setup done- no boost?
 

Haha, that's funny shiet :1 Post some pics man so we can help you out.

Re: Turbo setup done- no boost?
 

Sounds like a boost leak to me as well.

It also could be that the turbo is being restricted for some reason. Do you have a filter of any sort on there?

What kind of turbo is it?

Re: Turbo setup done- no boost?
 

No filter, its a Garrett T3 turbo. A/R .48 hot side. around .57 it looks like cold side. We plugged up a hole we found and ran it and it still wasnt boosting then something came loose. its our "lets hope it works" but it didnt rubber 90 degree coupler from turbo to straight pipe. We gotta get that fixed and see if we boost anymore if not we gotta keep looking

Re: Turbo setup done- no boost?
 

Fixed a wastegate leak, did some other things, Re did a piece of the piping its a lot better now. But still it jumps to 3 psi and holds there, no more.

The way I setup the boost gauge was normal from FPR line except that i needed an extension so i took a long piece of vacuum line and put it from the vacuum line on the BoV to where it should be. I dont know if that would make a difference.

The BoV sounds great by the way, you would 'think' its boosting full. The power seems like its more but not 8 psi worth.

Its still on a turbo basemap but i dont see why that would make that much of a difference even if it was the gauge that was bad.

Ugh heLp!

Re: Turbo setup done- no boost?
 

still need pics mang....that way we can see if something is missing or hooked up wrong instead of asking you 1 million questions about it

Re: Turbo setup done- no boost?
 

Gimme a little time, i have a couple more things i wanna try out since we found a couple leaks, but even after fixing the first one i wasnt boosting anymore it seemed. Gonna try and get this all hooked up right then ill check on the laptop what my map sensor is reading (since itll tell me if gauge is wrong or not) and God willing we'll get runnin

Re: Turbo setup done- no boost?
 

Went datalogging today with hondalog and crome pro, didnt hook up the wideband or anything like that, just wanted to test log and its funny cause ill get 5psi of boost reading on crome pro datalog but 2psi on my gauge x_x

Re: Turbo setup done- no boost?
 

My friend had his guage read 2psi off all the time, but that was only at the altitude we live at(mile high). See how it reads because you may be boosting before it actually starts reading it as boost.

Re: Turbo setup done- no boost?
 

it shouldnt be an issue, but try to have the boost guage the only source going to a nipple on the im and see if that changes anything....also does the guage sit at zero when the cars off, or is it 1 or 2 under

Re: Turbo setup done- no boost?
 

The gauge sits at zero, it doesnt sit under because this is strictly a boost gauge, no vacuum. Ill try relocating it. I should still be boosting 8 psi, but anyway i think im gonna move on to tuning

Re: Turbo setup done- no boost?
 

yea i dont have experience with those....i didnt see if you moved your wg line to the im yet, but that may help as well to get you closer to the 8psi. the way it is connected to the compressor it will crack early and you will also loose boost through your piping so it will never show 8psi on the boost guage hooked to your im

Re: Turbo setup done- no boost?
 

Thanks but how could i gain extra boost just by moving the wastegate to the IM?

Re: Turbo setup done- no boost?
 

i think what hes saying is that depending on where you boost guage is hooked up to it may show higher or lower boost than you actually getting, for example, if there is vacuum line on the turbo itself and the boost guage was hooke dup there it wold show higher than if it was a vacumme line at the end of the intake manifold(which is where it should be), your waste gate should also be hooked up at the last possible vacumme line on the intake manifold. Ig you had your wastegate set at the turbo and the boost gauge set at the intake than its going to be a different reading.

Re: Turbo setup done- no boost?
 

Ill try changing the vacuum line from wastegate to the intake manifold, see if anything good happens God willing

Re: Turbo setup done- no boost? *PIX NOW*
 

Here are some pictures. Should I hook vacuum line thats from wastegate to turbo, to wastegate to FPR line instead? Or would brake booster line be better?

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

in that 3rd pic it looks like you're missing something like a cross member...are you running w/o that? also i hope these are pics before you drove it, because the flange on the dp doesnt look like its been welded. isnt there something else on there you can tap into? i have mine hooked up where the pcv used to be hooked up, and the bov going to the nipple just to the right of it, then the boost guage is tapped into one of the nipples on the back.

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

also looks like the vacuum port on ur turbo is just open with nothing connected to it...get a plug in there

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

the wastegate is hooked up straght to the turbo and those integra dont come with cross members :P could be the w/g or the bov .. just a guess

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

Cross member huh? Anyway yeah there is something going to the turbo port, if i removed it and put it to the IM would i still have to plug up that? Cause I have two lines on my BoV and only one is hooked up right now. Anyway im not sure about all the nipples youve hooked up the lines too but the downpipe has a flange welded onto it and then thats bolted to the flange on the turbo.

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

p.s. i doubt that bolt on your charge pipe is air tight ( where the stock pvc hose goes on that intake) jus another thing id check

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

Oh you mean the one we screwed in? Its pretty thick...

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

A threaded item in a smooth walled hole would not be airtight. Think about that for a minute...done?...moving on then.

• Remove that screw/bolt
• plub all ports/nipples on turbo
• check wastegate seal
• Run WG vac line to compressor housing, keep it short

Bouble check all charge pipe couplers. If you found multiple leaks already I can't imagine everything else is flawless.

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

where is that wastegate vacuum line hooked up to, i cant tell by the pics, you have the BOV done right, there shouldnt be anything hooked up to the smaller nipple (its not hooked up on my car).

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

We covered the smaller nipple on the BoV today, I guess it doesnt matter. We rehooked some lines to the brake booster line instead. Wastegate still going directly to turbo..

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

did you plug or use the turboes hole for the vaccume. either plu git or use it for the waste gate.

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

you need a damn dump tube that goes beneth the oil pan! with out a dump tube, fumes from wastegate get sucked into turbo=loss of power no boost, make sure your wastegate vaccume line is hooked to turbo compressor nipple if there is one, if not make your own anywhere from compressor b4 throttle body.

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

^dont listen to this guy

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

no... the smaller nipple can be connected but its not needed if u want, run a line from turbo to wastegate it (should be connected like this even if no bov is used) and T off the line and connect that to the smaller nipple... the larger nipple on the bov goes anywhere after the throttlebody vaccume. and you really should run a dump tube from wastegate under the car

Re: Turbo setup done- no boost? *WITH PIX NOW*
 

check all your fernco worm-clamps to make sure they are tight. the nipple on the bottom of the wastegate should go strait to your turbo with the boost controller teed inline. ignore the top nipple unless you are using an ebc, you dont need to plug it. check your bov for leaks, have someone rev your motor and put your cock over it to feel for a leak. listen for ticking at the manifold. thats the sound of a pissed off leak. make sure all of your potential leak areas arent leaking.
