PURE Turbos Stage 2 Turbo Upgrade 2016-2026 Cadillac ATS-V CT4-V

The LF4 3.6L twin-turbo V6 in the ATS-V and CT4-V Blackwing responds strongly to a tune, and the small factory turbos are the first thing it outgrows. PURE Stage 2 rebuilds the factory turbos with billet compressor wheels, high-flow turbine wheels and an upgraded CHRA while keeping the OEM housings, so they bolt back in where they came from. PURE rates it at more than 720 wheel horsepower with fuel, supporting mods and a custom tune.

What PURE changes inside

PURE fits a billet compressor wheel and a high-flow turbine wheel sized for the LF4 3.6L V6, then upgrades the center housing rotating assembly (CHRA) to handle the higher shaft speed and boost. Every unit is balanced on a VSR high-speed balancer before it ships. The factory compressor and turbine housings are kept, so the turbos mount in the factory location and work with the factory plumbing and heat shielding, with no cutting or fabrication.

How the core charge works

PURE builds this upgrade from a factory turbocharger core, so you choose how to supply one when you order:

• Send in your turbos first (no deposit): you ship your factory turbos to PURE, they are rebuilt to this spec and shipped back. You pay only the upgrade price.
• Pay a refundable core deposit: PURE ships a finished upgrade from stock right away. The deposit shown in the option name is added to the price, and it is refunded in full when PURE receives your old turbos in rebuildable condition within 60 days of delivery.

Before you ship a core, remove the oil lines, coolant lines, actuators and inlets. Cores that arrive damaged or incomplete may not get the full refund, so call us before you send one if you are unsure.

The Add Core option pays the refundable core deposit so PURE can ship from stock. Choose No if you will send in your own turbos first.

Warranty and use

PURE backs its turbo upgrades with a limited 1-year, unlimited-mile warranty. A custom ECU tune is required, and the warranty assumes a qualified tuner and installer. This part is for off-road and competition use only and is not legal for street use in California or other states with similar emissions rules.
