Turbo Problem, Compressor Housing Spinning On Bearing Cartridge.

[Bass Junky]

Hey guys,

Well, I just pulled apart my intake bits around the turbo to fit my super cool silicone inlet pipe, and whilst doing this I have noticed that the compressor housing can be rotated with very little effort on the bearing cartridge.

This is the first time I've had any of this area apart since the turbo has been installed, and I've been having a little trouble holding boost up the top, according to my dyno chrat.

A) Is there a way to tighen the bugger up without removing the turbo? (doesn't look like there is)

B) Has this happened to anyone else, the housing working loose that is?

C) you do you think this might be the reason it's not holding boost? (only dropping off and a little bit wavy, but this might also me from back pressure in the exhaust turbine....

Thoughts?

The housing is bolted on by a series of bolts isnt it Pete?

It would just be a matter of tighting all of them up.

Unless the hi-flows/stockers are different from say a GT frame turbo, as i know mine was just 6 bolts to hold the comp housing on.

The first thing to work out is if the comp housing is turning on its backplate or if the housing and backplate are rotating on the front of the bearing housing . It would help to know what kind of turbo it is too because for example some Garrett GT BB turbos fix the backplate to the bearing housing with a large circlip . Others like T3 or T4 based turbos have the backplate bolted to the front of the turbos bearing housing .

Cheers A .

Its a GCG hi-flow

Yeah, it's spinning on the 6 bolts that hold the housing section on.

I tried to get in there but there's too much crap around it.

I'm thinking this is going to be a 'turbo out' excursion?

I would say so dude, if you cant get to them all it'll have to be outed

ahh, its a 30 min job to pull the turbo off anyway.
