I don't think I've ever made such a rudimentary post, but I'm completely mystified as to how I need to tighten the front/ inner turbo stud nut. The nut takes a 17mm / 11/16" wrench. I even loosened the turbine to compressor junction to possibly allow more room and it seems absurdly difficult. I spent at least 30 mins trying to get the nut on and the rear inner stud I actually had to cut down a bit as it was hitting the exhaust housing.

 

I was thinking maybe I need smaller flange nuts like those in this treadstone kit:

Might be easier to install just the turbine housing by itself first.

 

Yes.

I've also tighten them using an 11/16 offset wrench before.
had a customer use a smaller grade 8 bolt and nut.
Not my choice but was told it worked.

The inner rear stud. Install upside down. So only the short end of threads are up.

 

Drill out threads...run 3/8 bolt up from bottom

 

Probably could do use a 5/16.

 

Thanks guys. I ended up doing exactly this. #1 remove compressor housing. #2 remove turbine. No sweat with the turbo on the bench. #3 bolt turbine housing to manifold. #4 reinstall turbine with housing already bolted down. This was for sure difficult and I need to come up with a better solution for when the turbo comes off next. There was absolutely no way to confidently and evenly tighten down those nuts with the turbine in place. I'm gonna need to check myself into the psych ward when I pull the turbo next time.

Also the rear inner stud needed to be trimmed a 1/4" to clear the turbine housing.

Are these symptoms of the Master Power turbo or just the name of the turbocharging game?

 

Just apart of it.
Call me or email me when you have questions.
Like about that oil gasket.

The rear inner stud you just needed to flip it over and install the long end first.

Also the Borg large frame T4 turbo you need to flip rear stud as well. Front is easier to get to. Small turbos in a tight area.

 

Thanks Rick I do appreciate all the weekend emails you've replied to basically instantly! I'm not much of a phone call guy lol. So the rear inner stud I assume does not get bottomed out when it is threaded from the long end first, correct? Because the short end doesn't give enough thread engagement if the long end is bottomed out.

I like the idea of drilling and tapping the turbine housing for a small head 3/8" bolt and then drilling out the manifold as well. Then i can do away with that 4th stud and turbo R&R will be 5 mins instead of an hour+.

 

Your welcome.
You will screw the rear inner stud long end in. Not all the way.
Install the turbo. Then screw that stud down where there's the nits thickness plus a thread or two showing.
When you tighten the nut if it's to long. It will screw down into the manifold.

The front drill method in front inner bolt.
You just drill the manifold out. Won't take much. To get a 3/8" bolt slips through. Then just use a bolt and nut.

Have you tried a crows foot?
