Stock Plus Billet Turbo (E99) | 7.3 Powerstroke Drop-In

The KC Stock Plus Billet Turbo (E99) is a stock-sized drop-in turbo for 7.3 Powerstroke pickup trucks, supporting stock to 160cc injectors. It uses a KC billet compressor wheel, an SXE-style turbine wheel, an upgraded 360 thrust journal bearing design, an adjustable wastegate actuator, and a high-flow non-EBPV outlet flange. No core return is required. All gaskets, o-rings, and the factory intake boot retention make this a true drop-in upgrade over the stock turbo.

This is a balanced-assembly upgrade of a stock-sized turbo - faster spool, cooler running, and more power than stock, without stepping up to a larger frame.

Why the Stock Plus Billet Turbo Beats Stock

The Stock Plus Billet is a stock-sized turbo that has been completely gone through and upgraded - faster spool, cooler running, and more power than the factory unit, while retaining the factory intake boot for a true drop-in install.

Buy the Stock Plus if you want better-than-stock performance on a stock or near-stock truck. Step up to a larger drop-in turbo if your injectors exceed 160cc or you want a true performance frame. No core return is required, and the kit includes all gaskets and o-rings.

Buyers comparing the Stock Plus Billet vs the DIY Balanced Assembly should choose the Stock Plus when they want a pre-built, drop-in-ready turbo with the 1-year unlimited-miles limited warranty - rather than building the turbo themselves.

What the Balanced Assembly Adds

The Stock Plus Billet uses a KC billet compressor wheel paired with a KC SXE-style turbine wheel inside a stock-sized housing. The result is faster spool and cooler running than the stock turbo without changing the frame size or required supporting parts.

The center section uses an upgraded 360 thrust journal bearing design for added stability under load. An adjustable wastegate actuator handles boost control, and the high-flow non-EBPV outlet flange improves exhaust flow on the back side of the turbo.

This is essentially a pre-built balanced assembly with a 1-year unlimited-miles limited warranty - drop-in ready compared to the DIY Balanced Assembly path, with the factory intake boot retained.

What Comes In The Box

• Stock Plus Billet turbocharger (E99)
• High-flow non-EBPV outlet flange
• Adjustable wastegate actuator
• All gaskets and o-rings for installation

Gaskets and o-rings are included for the turbo install. The factory intake boot is retained. Up-pipes, EBPV pedestal upgrades, and tuning are sold separately and recommended for best results.

Recommended Supporting Upgrades

For best results with the Stock Plus Billet, three upgrades are recommended but sold separately:

• Upgraded up-pipes
• Upgraded EBPV pedestal
• Hydra programming chip

None of these are included with the turbo. Plan your build accordingly before adding the Stock Plus Billet to your cart.

Exhaust Brakes and Aftermarket Parts

Exhaust brakes are a customer-verified install with this turbo. Some brake brands have clearance issues that can hinder performance, rub the turbine wheel, or cause other issues because of how the flapper closes. The added back pressure can be hard on the turbo and motor. Verify fitment and functionality with your specific brake before installing.

Powder Coating and Polished Cover Options

Powder coating adds up to a 3-week lead time before the turbo ships. Turbos ship with the duller factory finish unless a polished cover is specifically requested. A polished cover is available as a $250 add-on with a two-week lead time. The turbo pictured shows a polished cover.

Avoid These Common Mistakes

• Ordering for a van without planning intake boot and downpipe modifications.
• Running larger than 160cc injectors with the Stock Plus.
• Expecting larger-frame performance from a stock-sized turbo.
• Assuming exhaust brake compatibility without verifying clearance.
• Skipping the recommended up-pipes, pedestal, and Hydra chip.
• Forgetting the lead time on powder coating or polished covers.

Fitment Coverage

Designed for direct fit on 7.3 Powerstroke equipped pickup trucks. Will drop into 7.3 equipped vans, but the intake boot and downpipe must be modified for proper fitment.

Final Fit Check

• 7.3 Powerstroke pickup confirmed (not a van).
• Injectors are 160cc/stock% or smaller.
• Supporting upgrades (up-pipes, pedestal, chip) planned separately.
• Non-CA / non-CO shipping address confirmed.
• Lead time understood if powder coat or polished cover is added.

For a stock or near-stock 7.3 Powerstroke pickup that needs a better-than-stock drop-in turbo with no core return, this is the right Stock Plus Billet to order.
