Do you do anything to the stock Turbo
 

Ive got the turbo off the manifold. Is there anything I should do to make it better???? IE wastegate delete or anything else.

And will it upset anything if I turn the cold side of the turbo up or down? It has a circlip on the back that looks like it will let things rotate.
Sorry for the dumb questions but cummins are new to me and we dont have any diesel motor sports down here.
Ive done the powerstroke upgrades and that caused a connecting rod to run side ways in the sump so now its time to make a fummins. :humm::argh:
