Nic Posted May 19, 2008 Share Posted May 19, 2008 I don't think GReddy sell the internals separately only the housings, your best bet may be either to get it rebuilt by a specialist turbo company or swap for a new one. Quote Link to comment Share on other sites More sharing options...

Homer Posted May 19, 2008 Share Posted May 19, 2008 Wouldn't it be worthwhile replacing with a more modern, faster spooling turbo? If the T78 is borked then it's hardly one worth fixing IYSWIM. Quote Link to comment Share on other sites More sharing options...

I would stick to the T78 because the great durability Greddy offers. That is also the reason I bought a T78-kit instead of the faster spooling DBB67.

tooquicktostop Posted May 20, 2008 Share Posted May 20, 2008 IYSWIM (if you see what I mean) I would ditch the T78, old slow to spool turbo which has had its day, it is completly outclassed by modern turbos like the GT ranges and T04Z/T67 DBB IMO, I have had T78, T88, T04R, T04Z and fitted a T67 DBB now, I would never go back to the laggy huge turbos again for road use Quote Link to comment Share on other sites More sharing options...

If the T78 is borked then it's hardly one worth fixing IYSWIM. i would have to change the downpipe for that, and a dbb turbo is arround 1800€ delivered with taxes to germany. a borg warner bastard with new turbo design and very small gap width build in my t78 is arround 1000€, a complete new borg warner turbo 1200€ its build for an engine lifetime and can be repaired in 2 days in germany. if one of these US turbos is broken you can throw it in the next trahscan.

georigg Posted May 23, 2008 Share Posted May 23, 2008 Although I do not have a TT I'm a Rotating Equipment Engineer(have an NA). If the inlet and exhaust "wheels" or impellers are attached to the same shaft and you are replacing one only impeller, then you WILL need to have the whole rotating assembly balanced. Turbos usually turn at very high revs and out of balance goes up exponentially. Although one Impeller can be balanced on its own, as soon as you fit it to a shaft, it is necessary to balance the whole assembly as the dynamic balance will be affected. Normally when assembling shafts/impellers, you balance the components then assemble and do a re-balance on the whole rotating assembly. Some engineers prefer to balance only the rotating assembly, however as an "oldy" my preference is to do components to a "rough" balance then assemble and do a final. Not to do so at all will result in imbalance and that will lead to failure. Rgds George Quote Link to comment Share on other sites More sharing options...
Spoony Posted May 24, 2008 Author Share Posted May 24, 2008 it will be rebalanced, thats why i send the complete turbo to them Quote Link to comment Share on other sites More sharing options...
