DNA Motoring TM-K20-S Stainless Steel Turbo Manifold

Why Upgrade Your K20 Turbo Manifold?

The factory setup isn’t designed for turbocharging. That means:

• Restricted exhaust flow
• Slower turbo response
• Limited power potential

This manifold fixes that by:

• Improving exhaust flow efficiency
• Increasing turbo spool speed
• Supporting higher horsepower builds

Translation: more airflow = more boost = more fun.

The heart of any Turbo system is the Manifold and the Turbocharger. These form the basis where the rest of the turbo system is built around.

Vehicle & Engine Compatibility

Designed for:

• Honda K20 engines
  • K20A / K20A2 / K20Z variants

Common swaps/builds include:

• Honda Civic (EP3 / FG / FA builds)
• Acura RSX Type-S
• Custom K-series swaps

(Fitment depends on chassis and turbo setup—because K-swaps are never simple.)

Turbo manifolds have only one, but the most critical purpose in turbo systems, and that purpose is to expel exhaust gas into the turbine of a turbocharger as efficiently as possible. There is no match for power and performance for tubular stainless steel manifolds. Tubular manifolds are made up of runners coming from each cylinder, meeting up at a collector. Tubular manifolds yield a higher efficiency rate, as each runner is generally the same circumference.

K20 turbo manifold stainless steel DNA Motoring – Key Features

• High-Flow Stainless Steel Construction
  Built to handle extreme heat and resist cracking under boost.
• Tubular Performance Design
  Improves exhaust scavenging and turbo efficiency.
• Turbo Upgrade Ready
  Supports a wide range of turbo setups.
• Corrosion-Resistant Finish
  Built for long-term durability in harsh engine bay conditions.
• Performance-Oriented Layout
  Designed for serious turbo builds.

This tubular manifold furthers the even exhaust flow using “equal length” runners. Equal length tubular manifolds are the most efficient design, which ensures equivalent air flow rate smoothly from each cylinder.

What It Does Best

• Improves turbo spool time
• Increases exhaust flow
• Supports high-boost applications
• Enhances overall engine performance

This allows for a much smoother flow of exhaust gas to the turbo. Tubular stainless steel manifolds are chosen over cast manifolds for big power applications. Tubular stainless manifolds feature better and more consistent flow of exhaust gases. Most of the tubular Stainless manifolds also feature the placement of the waste gate flange towards the middle of the collector to allow accurate readings and precise control.

Performance Potential

Let’s not pretend:

• K20 + turbo + proper setup = massive power gains
• Easily capable of 300–600+ HP depending on build

This manifold is where that power starts.

What It Won’t Do

Let’s stay realistic:

• Doesn’t include turbo, wastegate, or piping
• May require custom fabrication depending on setup
• Not a plug-and-play solution for every build

This is a core component, not a complete kit.

Who Is This For?

• K20 turbo builders
• Civic and RSX enthusiasts going forced induction
• Anyone pushing beyond stock NA limits

If you’re boosting a K-series—this belongs in your build.

Installation Notes

• Professional installation recommended
• Ensure proper turbo placement and clearance
• Use high-quality gaskets and hardware
• Proper tuning required after installation

(Pro tip: Heat management is critical—wrap it or coat it.)
