Upgrade turbos

[ef-oh-onebimmer]

So I recently added 3in catless downpipes and a stage 2 tune from 412motorsports. Next I want to upgrade the turbos. Will I need to tune my car again once I add the bigger turbos. Also what else will I need to upgrade. Any suggestions on where to get the turbos?

no good options, all don't produce more power.
If you want to spend the money, donate it to a family in need, it will have a bigger impact. Pure Turbo's are fake gains and not verified.. Or you can run Alpina Turbo's for small gains.

How so? Bigger turbos typically give more boost

It’s been talked about and beaten to death.
Not the case for the n63.
There is forum members that actually did the upgrade for no improvement.

Alpina turbos. Slightly larger. Give slight improvements but that’s about it

We could talk about the adiabatic efficiency of a compressor, or better yet, the ideal gas law, or even air temperature versus oxygen. You pick....
