The C variant found in the new Z4 m40i (mostly Euro spec) and supra is a Bosch hpd6 Evo 3.5 bar pump which flows significantly more than the F series n55 pump.

So depending on which pump you have, you may or may not require additional fuelling to Max out a turbo upgrade.


I personally prefer the pure upgrade since they've been around for awhile and are quite reputable. But imo I would skip the hybrid turbos and go straight for a "stage 3" turbo to remove the restrictive factory turbo fold.
