Got a smoking deal on a slightly used 'bigger turbo'
Hope it gets here in one piece soon...
Its not one of the usual turbo's that are being used though..

Judging by the size of that picture, it IS a big turbo !

GT3076R CHRA ?

When is it being installed and when is the dyno booked ?

Thanks guys - it´s good to be here! I was registered here before but I had forgotten my password and my nick aswell ....getting old I guess.
It´s good to see that the GT3076 fits in that location.I have a GT3071R which is imho a little smaller in diameter at the compressor housing.Just waiting now for my parts to get back from balancing,then I can finally put the engine together.

New turbo has been started and run for the first time! Whoaha! I like this turbo already
This was just on the internal wastegate without WI and without any additional tuning, but already is clear that this 50% more flowing turbo only gave a 100 rpm later spool to make 1 bar boost
Proof:



It also holds its boost better and the internal wastegate doesn't creep (yet) as is shown by the steady boost line.
BTW: 200 MAP is 1 bar boost above ambient (=100). The wastegate boost goes on to about 1,15 bar boost (~17 psi).

That is awesome, good job picking a better turbo out for minimal increase in lag!

[70Turbobug]

Even without further tuning that is quite an improvement! My guess is that your intake temps are also lower due to the better effeiciency of this turbo.How much boost do you intend to run?
