Turbo Kits: forced induction from bolt-on upgrades to full turbine kits

A turbo kit adds forced induction by driving a compressor off your exhaust gas, packing more air into the engine so it can burn more fuel and make more power. On a factory-turbo truck a kit swaps in a bigger, better-flowing turbo and the plumbing to match; on a naturally aspirated engine it brings the turbine housing, manifold or mounting hardware, and the connections needed to route boost. That is real work under the hood, and the right turbo kits save you sourcing a dozen mismatched parts. Below is what ThreePiece actually stocks and how to pick.

What we stock

There are 8 turbo kits in stock right now from 4 brands: HKS, Garrett, BD Diesel and AMS. Prices currently run from $184 to $9,054 — that is the live range on what is in stock today, not a fixed quote. HKS has the most kits in the current mix, with Garrett and BD Diesel each contributing a pair.

Concrete examples span that spread. At the top end is the HKS Bolt On Turbo Kit GTIII-RS for the ZN8/ZD8 and the HKS GTIII-SS Sports Turbine Kit for the RB26. For late-model trucks there is the Garrett GT1752S PowerMax kit for the 2021+ Ford Bronco 2.7L, plus the BD Diesel Screamer kit for the 13-16 F-150 3.5L EcoBoost and the 11-12 F-150 3.5L EcoBoost version. Compact-car buyers can look at the Garrett PowerMax upgrade kit for the 2009-2023 Fiat Abarth 500 1.4L.

How to choose

The first split is factory-turbo upgrade versus adding boost to an NA engine. The BD Diesel Screamer and Garrett PowerMax kits are upgrades that replace an existing turbo on trucks like the Ford F-150, F-150 Raptor and Ford Bronco — largely direct swaps that trade the stock turbo for more airflow. The HKS turbine kits are heavier builds aimed at platforms like the RB26 and ZN8/ZD8, and they carry the higher prices to match.

The honest trade-off is scope. A PowerMax or Screamer upgrade keeps most of your factory hardware and plumbing, which keeps the install shorter. A full turbine kit is more power potential but more surrounding work and more supporting parts before it runs right. Match the kit to the platform first, then decide how far you want to take it.

What else you need with it

Boost stresses the whole engine, so plan the supporting parts. More air needs more fuel, so look at fuel pumps. Higher cylinder pressure is why builders reach for forged pistons and fresh head gaskets or a full gasket kit. Plumbing a kit means fittings and oil-feed adapters, and added heat load makes a stouter radiator worth a look. Browse everything under Engine Components.

Fitment and ordering

Coverage in the current kits centers on Ford and Fiat, with year ranges from 2009 to 2023. If your platform is not shown here, confirm before you buy — fitment help is available by phone at 813-535-5801. All orders ship with free shipping, and Affirm financing is available on larger builds.
