ATP GT35R Bolt-On Turbocharger MazdaSpeed 3 2007-2013
The massive GT35R turbocharger is a whole different animal than its little brothers listed above. Efficient up to 30 psi on the MS3 2.3L, this turbo will breach the 500-600hp range when maxed out with all supporting modifications and aggressive tuning. A fully built engine and full supporting modifications are highly recommended to safely run the GT35R. You can expect this turbo to spool around 800 RPMs later than the GT3071R on the 2.3L engine.
