    Porsche 718 performance parts

    Discover

    Porsche 718

    Cayman · Boxster · 2017–2024

    Chassis & Variants

    982 chassis · 2.0T (Base/T) and 2.5T (S/GTS) flat-four turbo

    Power Ceiling

    2.0L → ~440 WHP pump · 2.5L → 530+ WHP E85 + meth

    The 718 is the platform we know better than anyone. Stage builds are sequential — airflow and heat first, fueling next, then turbo and tune. The 2.0L tops out around 440 WHP on pump fuel; the 2.5L scales to 530+ WHP on E85 with methanol.

    Porsche 911 performance parts

    Porsche 911

    991.2 Carrera · 992 Carrera · 992 Turbo S

    Chassis & Variants

    991.2 Carrera 3.0 TT (2017–2019) · 992 Carrera 3.0 TT (2020–2024) · 992 Turbo S 3.7 TT (2021–2024)

    The 991.2 and 992 share the 9A2-Evo twin-turbo flat-six but diverge on fueling, clutch, and dampers. Our 911 catalog is built around the bolt-ons that actually move the needle on these cars: high-flow fueling for E85, PDK clutch capacity, and active suspension tuning.

    McLaren M838 performance parts

    McLaren M838

    570S · 570GT · 600LT · 650S · 12C

    Chassis & Variants

    M838T 3.8L twin-turbo V8 (2011–2025) — Sport Series and earlier Super Series chassis

    The M838T responds to turbo upgrades better than almost anything in its era. Our Velocity turbos drop into the OEM hot-side with fast-spool geometry and your choice of journal or ball-bearing CHRA — the same hardware we run on builds chasing big mid-range on factory fueling.

    McLaren M840 performance parts

    Discover

    McLaren M840

    720S · 750S · 765LT · Artura · GT

    Chassis & Variants

    M840T 4.0L twin-turbo V8 (2017–2025) — Super Series and LT chassis

    The 720S and 765LT respond to turbo upgrades exactly like the M838 cars did — but the 4.0L moves more air and tolerates more boost. Our 1244S turbos are the high-flow path for owners chasing the 800+ WHP range without touching the long-block.

    VAG 4.0 TFSI Twin-Turbo V8

    Chassis & Variants

    Shared 4.0L twin-turbo V8 across the RSQ8, Urus, Cayenne Turbo, and Panamera Turbo platforms

    Three badges, one engine. The VAG 4.0 TFSI is the same long-block under the RSQ8, Urus, and Cayenne Turbo — which means the same fueling, cooling, and turbo path scales across all three. Reach out for current platform availability while we expand the catalog.

    Common Questions

    Before you order.

    How do I confirm fitment for my exact car?

    Every product page lists chassis, model years, and engine code. If your car is borderline (early build, region-specific options, or a swapped engine), message the team with your VIN and we'll confirm before you order.

    Will these parts void my factory warranty?

    Bolt-on hardware doesn't automatically void coverage, but tuned ECUs and turbo upgrades are flagged by dealers. Most of our customers run the cars out of warranty or accept that powertrain claims may be denied — the gain is the trade.

    Are these parts street-legal?

    Catted downpipes and most bolt-ons are street-driven without issue. Catless hardware and aggressive tunes are sold for off-road and competition use; emissions rules vary by state and country — buyers are responsible for local compliance.

    Do you support remote tuning and install questions?

    Yes. Every build gets direct access to the team for install order, base map selection, and follow-up dyno or street logs. We'd rather you ask twice than guess once.

    What does shipping and returns look like?

    Hardware ships from inventory when in stock; turbos and built-to-order items are quoted with a lead time on the product page. Returns are handled case-by-case — see our return policy or contact the team for specifics.

    Not sure which stage you're on?
