Exhaust housing torque?
When it comes to critical mounting surfaces such as manifolds, waterpump etc. I'm a torque nazi.
I like to install a turbo by taking off the rear housing and torquing its flange evenly to the manifold, but am then presented with a problem of guessing the toruqe on the bolts holding the housing to the CHRA. You can't exactly get a torque ractchet on those babies, at least not all of them...may get some with a universal...so what should you do? I normally just get them all "even" and I've never had a problem, but I'm putting together another setup now and thought I'd pose the question. 1/2 turn past hand tight? 1/4 turn? BTW - turbo is a GT3574 from A-spec. |
You should be able to get a crows foot on it.

If you got your turbo from A-Spec, the info shoulld have come with the turbo as mine did.
From the Garrett spec sheet for GT turbos. V-band nut: 50 inch pounds except for GT40-50 110-130 inch pounds. Compressor: 145-165 inch pounds. Turbine: 185-215 inch pounds. |

Thanks, yes that info didn't come with mine.
13B-RX3: I can get one on, but not on all of them.....maybe I'm not trying hard enough :uzi: |
Maybe because my GT35R T3 is an actual production Garrett turbo which came in their box. Yours is an A-Spec bastard (good bastard) and they left out the card.
