1. On3 Performance SBC Twin Turbo Kit: Best Overall
The On3 Performance SBC Twin Turbo Kit stands out as a top choice for builders seeking serious horsepower. Based on owner feedback and the spec sheets, this kit includes twin T3/T4 turbos, cast iron manifolds, intercooler piping, and all necessary hardware. Many users report achieving over 800 wheel horsepower with proper tuning. The cast iron manifolds are a plus for durability and heat retention.
However, this kit is not a simple bolt-on. In our evaluation, the piping requires modifications to fit different chassis, and the lack of detailed instructions can frustrate beginners. We recommend this kit for experienced fabricators who want a high-quality foundation for a custom build. If you prefer a straightforward install, consider a more complete kit with vehicle-specific fitment.
- Twin turbo setup for impressive power gains
- Includes all necessary piping and hardware
- Cast iron manifolds for durability and heat management
Pros: Excellent power potential for the price; Complete kit with quality components
Cons: Requires significant fabrication skills for installation
2. CX Racing SBC Turbo Kit: Best Budget
For those on a budget, the CX Racing SBC Turbo Kit offers a solid entry point into forced induction. We researched owner reviews and found that this single T4 turbo kit can support up to 600 horsepower when properly tuned. The stainless steel manifolds are a nice touch at this price point, and the included intercooler helps keep intake temps down.
That said, durability is a concern. Several owners reported the piping is thinner than aftermarket alternatives, and some welds required touch-ups. In our evaluation, this kit is best for light street use or occasional track days. If you plan to push high boost levels or race frequently, you may want to invest in a more robust kit.
- Affordable single turbo setup for SBC
- Stainless steel manifolds resist corrosion
- Includes intercooler and blow-off valve
Pros: Very budget-friendly for a complete kit; Good power gains for mild builds
Cons: Thinner piping may require reinforcement
3. Speedmaster SBC Turbo Kit: Best Value
The Speedmaster SBC Turbo Kit delivers impressive value for builders targeting 500-700 horsepower. Based on manufacturer specs and user reports, the T70 turbo spools quickly and provides strong mid-range torque. The mild steel manifolds are sturdy and can be easily modified if needed. The kit comes with oil lines, fittings, and a blow-off valve, reducing the need for extra purchases.
However, the lack of a downpipe is a notable omission. Many owners had to fabricate or purchase one separately, adding to the total cost. Additionally, the instructions are basic. We recommend this kit for intermediate DIYers who are comfortable sourcing a downpipe and doing minor fabrication. If you need a true bolt-on solution, look elsewhere.
- Single T70 turbo for strong mid-range power
- Complete kit with oil lines and fittings
- Mild steel manifolds are durable and easy to modify
Pros: Great balance of price and performance; Kit includes most needed components
Cons: Downpipe not included
4. Garrett Motion SBC Turbo Kit: Premium Pick
The Garrett Motion SBC Turbo Kit is the premium option for those who refuse to compromise. Featuring the renowned Garrett GT3582R turbo, this kit is engineered for high performance and long life. The cast stainless steel manifolds are a standout, offering excellent heat management and resistance to cracking. Owner feedback consistently praises the fitment and power delivery, with many achieving over 700 horsepower reliably.
Of course, this level of quality comes at a cost. In our evaluation, the kit is significantly more expensive than competitors, and it may be overkill for mild street builds. We recommend this kit for serious racers or enthusiasts building a high-horsepower SBC who demand reliability and performance. If budget is a primary concern, consider the On3 or Speedmaster kits.
- Garrett GT3582R turbo for proven reliability
- Cast stainless steel manifolds resist cracking
- Precision engineering for excellent fitment
Pros: Top-tier turbocharger from a trusted brand; Superior build quality and durability
Cons: Premium price tag
5. ProFlo SBC Turbo Kit by Edelbrock: Easiest Install
The Edelbrock ProFlo SBC Turbo Kit is designed for enthusiasts who want a hassle-free turbo installation. Based on our research, this kit is one of the few true bolt-on options that includes an ECU and wiring harness. The self-tuning feature makes it accessible for those new to forced induction. Owner feedback highlights the straightforward installation and smooth drivability.
However, the power potential is limited to around 550 horsepower, which may disappoint those chasing big numbers. In our evaluation, this kit is best for street-driven SBCs where ease of use and reliability are priorities. If you plan to build a high-horsepower race engine, this kit may hold you back. Consider the Garrett or On3 kits for more headroom.
- Bolt-on design for easy installation
- Includes ECU and wiring harness
- EFI compatible with self-tuning capability
Pros: Simplest installation among kits; Complete system with tuning included
Cons: Limited power ceiling for high-hp builds
6. Turbonetics SBC Turbo Kit: Race Ready
The Turbonetics SBC Turbo Kit is built for racers who demand the highest power levels. With a T76 turbo and TIG-welded stainless steel piping, this kit is designed to handle over 1,000 horsepower. Owner feedback from track users confirms its ability to deliver consistent performance under extreme conditions. The included wastegate and blow-off valve are high-quality components.
However, this kit is not for the faint of heart. Installation is complex, and professional tuning is mandatory to avoid engine damage. In our evaluation, the cost is also a barrier for many. We recommend this kit for dedicated race cars or high-horsepower street builds where budget is secondary. For a more street-friendly option, look at the Edelbrock or Speedmaster kits.
- High-flow T76 turbo for maximum power
- TIG-welded stainless steel piping for strength
- Includes wastegate and blow-off valve
Pros: Excellent power potential for racing; High-quality construction
Cons: Expensive and requires professional tuning
7. ZEX SBC Turbo Kit: Niche Pick
The ZEX SBC Turbo Kit is a niche option for those with limited space or a modest power goal. Based on owner feedback, this single T3 turbo kit is designed for low-boost applications, supporting up to 450 horsepower. The compact size makes it ideal for engine swaps or tight chassis. Installation is relatively straightforward, making it accessible to beginners.
However, durability is a concern. Several users reported issues with the turbo failing under sustained high boost. In our evaluation, this kit is best for mild street builds or show cars that see occasional use. If you plan to push the engine hard or drive daily, invest in a more robust kit like the Speedmaster or On3.
- Compact turbo for tight engine bays
- Simple installation with basic tools
- Good for low-boost street applications
Pros: Fits in cramped engine compartments; Affordable entry into turbocharging
Cons: Limited power and durability
Frequently Asked Questions
What size turbo kit do I need for my small block Chevy?
The turbo size depends on your power goals and engine setup. For 400-600 horsepower, a single T4 or T70 turbo is common. For 600-1000+ horsepower, twin turbos or a large single like a T76 are recommended. Consider your camshaft, fuel system, and transmission when choosing.
Can I install a turbo kit on a stock small block Chevy?
Yes, but with caution. A stock SBC can handle low boost (5-7 psi) safely, but for higher boost, you need forged pistons, stronger rods, and a better fuel system. Always upgrade the fuel pump and injectors to avoid lean conditions.
Do turbo kits come with a tune?
Most kits do not include a tune. You will need to have the engine tuned by a professional or use a standalone ECU like Holley Terminator or Megasquirt. Some kits like the Edelbrock ProFlo include a self-tuning ECU.
How much horsepower can I expect from a SBC turbo kit?
It varies widely. A basic kit on a stock engine may add 100-150 hp. A high-end kit with proper supporting mods can produce over 1,000 hp. Realistic goals for a street build are 500-700 hp with a good turbo and tuning.
What other modifications are needed when adding a turbo?
You should upgrade the fuel system (pump, injectors, lines), ignition system, and cooling system. A blow-off valve, wastegate, and intercooler are essential. Also consider stronger head gaskets and studs for higher boost.
