Boost Logic Widowmaker Turbo Kit for 991 Porsche 911 Turbo
Boost Logic’s Widowmaker Turbo Kit for 991 Porsche 911 Turbo replaces the factory turbochargers with Boost Logic turbos built on billet bearing housings and billet compressor wheels, sized for the 991 Turbo in three power levels. Boost Logic designed the kit to use the factory oil and water lines through CNC billet adapters, which it says saves installation time and gives a leak-free, plug-and-play fit. The 1100 hp level is rated by Boost Logic on a stock motor, while the 1300 hp level assumes an upgraded clutch and built motor and the 1500+ hp level an all-out build, so the right choice depends on how far the rest of the car is going.
What the Kit Includes
- The kit ships with Boost Logic Signature Gold Coated Manifolds, TiAL external wastegates and custom provisions for adapting OEM-style intercooler piping. Boost Logic mandrel bent aluminum intake piping connects to the factory airbox or a Boost Logic intake kit, a billet exhaust adapter mates the turbos to OEM or OEM-style exhaust systems, and billet CNC oil and water line adapters come with custom heat shielding, installation hardware and clamps.

Frequently Asked Questions
- Which power level of the Boost Logic Widowmaker Turbo Kit for 991 Turbo should I choose? Match the level to the engine. Boost Logic rates the standard 1100 hp level for a stock motor with quick spool. The 1300 hp level is intended for a car with an upgraded clutch and a built motor, and the 1500+ hp level for an all-out build. All three levels of the Widowmaker Turbo Kit for 991 cars are listed at the same price.
- Does the kit use the factory oil and water lines? Yes. Boost Logic designed the Widowmaker kit to use the factory oil and water lines, connected through CNC billet adapters with custom heat shielding. Boost Logic says this saves installation time and gives a leak-free, plug-and-play fit on the 991 Turbo, and the adapters, installation hardware and clamps are included in the kit.
- Is a tune included? No. Boost Logic does not list an ECU calibration as part of the kit. A turbocharger upgrade at these power levels needs a matching calibration, so arrange the tune with your preferred tuner before the car goes back on the road, along with any fuel system changes the tuner asks for at your chosen power level.
- Will it work with my factory exhaust and intake? Yes. The kit includes a billet exhaust adapter that mates to OEM or OEM-style exhaust systems, and mandrel bent aluminum intake piping that fits the factory airbox or a Boost Logic intake kit. It also has custom provisions for adapting OEM-style intercooler piping, and Boost Logic sells a twin intercooler upgrade for the 991 Turbo separately.
- Can the 1100 hp level run on a stock engine? Yes, per Boost Logic. The standard kit is rated for up to 1100 hp on a stock motor with quick spool. Boost Logic does not state the fuel, tune or measurement method behind that figure, so discuss the exact setup with Bulletproof Automotive and your tuner before ordering, and remember the 1300 hp and 1500+ hp levels need a built engine.
