Boost Logic Pistons for 991 Porsche 911 GT3
Boost Logic’s Pistons for 991 Porsche 911 GT3 are a piston set for the naturally aspirated GT3 and GT3 RS flat-six, ordered by generation and model so the set matches the engine it goes into. That choice matters because the 991.1 GT3 uses a 3.8-liter engine while the 991.2 GT3 and both GT3 RS generations use the 4.0-liter. Boost Logic publishes almost nothing beyond the part name, so treat this as an engine-builder part and confirm compression, bore and contents with Bulletproof Automotive before ordering.
Features
- Generation-specific set for the 991.1 or 991.2 engine
- Model-specific set for the GT3 or GT3 RS
- Designed as an engine-build part for the naturally aspirated flat-six
- Pairs with the Boost Logic titanium connecting rods for the same engines

- Porsche 911 GT3: 991.1 | 2014-2016 | 3.8L Flat-Six

Frequently Asked Questions
- Which generation and model should I choose for the Boost Logic Pistons for 991 Porsche 911 GT3? Match the options to the car. Choose 991.1 for a 2014 to 2016 GT3 or the 2016 GT3 RS, and 991.2 for a 2018 or 2019 GT3 or GT3 RS, then choose GT3 or GT3 RS. The 991.1 GT3 runs a 3.8 liter flat-six and the others a 4.0 liter, which is why Boost Logic asks for both details.
- What comes in the set? Boost Logic does not publish a contents list for the Pistons for 991 Porsche 911 GT3 engines. The product photo shows six pistons with wrist pins and piston rings, one piston for each cylinder of the flat-six, but that should be confirmed before ordering. Contact Bulletproof Automotive and we will confirm the contents for the version you need.
- Are these forged pistons? Not confirmed. Boost Logic does not state the construction or material of these pistons, so no claim is made here. Ask Bulletproof Automotive to confirm the construction, compression ratio and bore size with Boost Logic for your generation and model, and share the details of the planned build so the engine builder can check the specification.
- Do they fit the 992 GT3? No. Boost Logic lists these pistons for the 991 generation GT3 and GT3 RS only, in 991.1 and 991.2 versions. The 992 GT3 is not listed, so owners of the newer car should contact Bulletproof Automotive to ask whether Boost Logic offers internal engine parts for that engine.
- Can the pistons be fitted without removing the engine? No. Replacing pistons means removing and disassembling the engine, so this is work for an experienced engine builder during a rebuild. Budget for machine work, gaskets and the rest of the rotating assembly at the same time, and consider the Boost Logic titanium connecting rods for the 991 GT3 if the rods are being replaced too.
