3. BorgWarner S256 SX-E Turbo Kit with Cast Iron Manifold: Best Value
The BorgWarner S256 SX-E kit offers impressive performance at a more accessible price point. The S256 turbo features a billet compressor wheel that provides quick spool and solid mid-range power, while the cast iron manifold is built to withstand high temperatures without cracking. The kit includes a 38mm wastegate, 3-inch downpipe, intercooler, and all required piping. In our evaluation, this kit delivers reliable power gains for street-driven B series cars without breaking the bank.
However, the included wastegate and blow-off valve are generic units that may not have the same longevity as premium brands.

It uses a stainless steel manifold that is more durable than mild steel, and includes a 44mm wastegate and blow-off valve. The kit is designed for serious performance builds and has a strong following among Honda enthusiasts who track their cars.
However, this kit is not for the faint of heart. The large turbo spools late, making it unsuitable for daily driving or autocross.

Beginners or those seeking a responsive street setup should skip this kit; it’s intended for experienced builders chasing maximum power numbers.
- Garrett GT3582R turbo for massive top-end power
- Stainless steel manifold for corrosion resistance and durability
- Includes 44mm wastegate and blow-off valve from reputable brands
Pros: Excellent high-rpm power potential; Stainless steel manifold resists cracking
Cons: Significant turbo lag on stock engines; Requires extensive supporting modifications
6. Rev9 B Series Turbo Kit with T04E Turbo and Intercooler: Entry Level
The Rev9 B Series Turbo Kit is the most affordable option for those wanting to turbocharge their B series engine on a shoestring budget. It uses a T04E turbo and a cast iron manifold, which is a step up from the mild steel found in some other budget kits. The kit includes an intercooler and all necessary piping. Some owners report decent results with proper tuning, making it a viable option for a low-budget build.
However, quality control is a concern. The turbo may have balance issues, and the intercooler cores are not as efficient as higher-end units. The piping often requires trimming or additional couplers for a proper fit. This kit is best for those who are handy with fabrication and not afraid to replace components as needed. It is not recommended for reliable daily driving or high boost levels.
- T04E turbo with .50 A/R compressor for quick spool
- Cast iron manifold for better heat resistance than mild steel
- Complete piping kit with silicone couplers
Pros: Lowest price among complete kits; Cast iron manifold is more durable than mild steel
Cons: Turbo quality is inconsistent; Intercooler piping may require modification to fit
7. Greddy B Series Turbo Kit with TD05H-18G Turbo: Trusted Brand
The Greddy B Series Turbo Kit is a classic choice that has been used by many Honda enthusiasts for years. It features a Mitsubishi TD05H-18G turbo, which is known for its reliability and strong mid-range pull. The kit includes a cast iron manifold, intercooler, and downpipe. Owner feedback often praises the kit’s fitment and overall quality, making it a trustworthy option for a street-driven B series car.
However, this kit may be harder to find as Greddy has shifted focus to newer platforms.

The turbo is also smaller than some modern options, limiting peak power potential. This kit is ideal for those who want a proven, bolt-on solution for 300-400 horsepower, but not for those chasing big numbers.
- Mitsubishi TD05H-18G turbo for reliable mid-range power
- Cast iron manifold and quality intercooler for durability
- Includes all gaskets and hardware for installation
Pros: Well-known brand with good support; Reliable turbo that holds boost well

Frequently Asked Questions
What is the best turbo kit for a B series engine for daily driving?
For daily driving, a kit with a quick-spooling turbo like the Garrett GTX3076R Gen II or the BorgWarner S256 SX-E is recommended. These provide good low-end response and reliable power without excessive lag. The Garrett kit offers premium build quality, while the BorgWarner kit provides excellent value.
Do I need to upgrade my engine internals before installing a turbo kit?
It depends on your power goals. For boost levels under 8-10 psi on a stock B series engine, many owners have had success without internal upgrades. However, for sustained high boost or power above 300-350 wheel horsepower, forged pistons and rods are highly recommended to prevent engine failure.
Can I install a turbo kit myself, or should I hire a professional?
Installation requires mechanical knowledge, including engine disassembly, fabrication skills for routing piping, and electrical work for sensors and tuning. If you have experience with engine swaps or forced induction, a DIY installation is possible. Otherwise, professional installation is advised to avoid costly mistakes.
What supporting modifications are needed for a turbo kit?
At minimum, you will need a standalone engine management system (like Hondata or AEM), larger fuel injectors (550cc-1000cc depending on power), a high-flow fuel pump, and a quality tune. Upgraded clutch, exhaust system, and cooling system are also recommended for higher power levels.
How do I choose the right turbo size for my B series engine?
Turbo size should match your power goals and driving style. Smaller turbos (like T3/T4 or TD05H) spool quickly and are great for street use, while larger turbos (GT3582R, Precision 6262) make more top-end power but have more lag. Consider displacement: B18C engines can handle larger turbos better than B16A. Use a compressor map to select a turbo that stays within its efficiency range for your target boost.
