Update: I’m sorry, I mis-read your question — you’re looking for a stage kit for the 2015 model year Regal, not the 2013. It will be interesting to see if such a kit is offered, since the 2.0T LTG engine in the 2015-2017 Regal is shared with the ATS, CTS and CT6 as well as the new 2016+ Camaro; it’s an entirely different engine from the one 2.0T in the 2011-2014 Regal Turbo. At this point, there’s nothing… but I’m hopeful.
I believe you’re looking for GM part #12653664.
It’s a Buick Performance Turbocharger Upgrade Kit that has the following impact on power ratings:
2012-2013 Buick Regal GS
Horsepower: 272 hp stock > 295 hp with tune
Torque: 295 lb-ft stock to 335 lb-ft with tune
2012-2013 Buick Regal Turbo
Horsepower: 200 hp stock > 270 hp with tune
Like all stage kits, this one requires an ECU tune.
