Rein Turbos for BMW 4 Series F36 (2015+)

Clear BMW chassis

Please ensure your correct model is selected

If more boost and reliability are your goals choose from one of our BMW turbo upgrades. Our turbo upgrades range from stock turbos rebuilt with stronger internals to all-new, ground-up turbo upgrades. BMW turbos such as the N54 are capable of really impressive power numbers on stock engine internals but the factory turbos lack the precise tolerances and reliability that an upgraded unit will deliver. In other words, the stock turbos can only do so much and if big power (>400whp) is your goal a turbo upgrade must be in your plans. Our partners are leading experts in turbo technology and upgrades. Each Stage has been professionally developed and tested. Additional upgrades and tuning may be, or is, required. Contact us for more details on tuning options.
