Hello
I just finished doing everything in the title and now I have no boost, it doesn't even get out of negative boost. I suspect the WGA. What could I have done wrong?

 

Be sure that the WGA is installed and adjusted properly. 2-3mm of preload is required. If the WGA is installed without preload (open partly at idle) then the turbo will not spool up.

Of course there could be about 100 other things going on, but that is somewhere to start I suppose.

BOOST ON!

I adjusted the WGA, checked all intercooler piping still no boost. I'm not sure what else to do. If I had a small leak in my intercooler piping I'd at least show a little boost right?

 

Something has to not be hoked up, even with a leak you should see SOME boost. You sure you hooked everything back up when you installed? Wga, mbc, all turbo lines and such?

 

I've looked over everything it's all hooked up.

 

Are you running off the wastegate or do you have a mbc?

 

mbc

 

Little more info.... Car idles normal. I've checked everything 10 times it's all hooked up and tight. When revved to 5000rpm I'm still at -10psi boost. Man this sucks I spent 10-12 hours on this to do everything right. I was so proud of myself and now this, what a bummer. Any ideas? HELP!!!!!!!

 

are you revving in gear? You need load to build boost.

Try running a vacuum line from the compressor directly to the WGA and try to get into boost.

 

check if the boost gauge is hooked up, make sure the mbc is hooked up correctly and check the wastegate as well if not take it to a shop

 

No I'm not in gear. I didn't know you needed load to build boost. Guess this could be the problem .

 

edit

 

Like he said, try running wastegate pressure.

 

I just realized the guy isnt driving the car, he is free rev-ing it.

DOH!

 

might be your problem...
