Description

Billet Intake Adapter for 1" Tillotson HW Carburetors – Fits Honda GX200 & Clone Engines


The EC 448HWINT Billet Intake Manifold is engineered to adapt 1.00" (25mm bore) Tillotson HW-Series carburetors to Honda GX200-style small block engines and their clones. Precision CNC-machined from billet aluminum, this intake offers superior fitment, airflow, and durability compared to generic cast adapters.


Key Features:

  • Precision CNC Machining – Matches the common D-shaped intake port on GX200-style cylinder heads for improved flow and sealing.
  • Optimized Airflow – Designed specifically for racing applications to reduce turbulence and improve throttle response.
  • Built-In Pulse Fitting – Pre-installed for seamless hookup to a fuel pump.
  • Reliable Mounting – Comes with hardware and intake gasket for a quick, secure installation.


What's Included:

  • CNC Billet Intake Manifold
  • Intake Gasket
  • Pre-installed Pulse Fitting
  • Mounting Bolts


Compatibility:

Fits 1.00" (25mm bore) Tillotson HW-Series Carburetors
Compatible with most Honda GX200-style small-block engines and performance clones:

  • Honda GX200 / GX160
  • Box Stock Project 196
  • Tillotson 196R / 212 / 225 / 228 / 236 / 268
  • Ducar 196 / 212 / 224
  • Predator 212 (Hemi & Non-Hemi)
  • Predator 224
  • Wildcat 223 / 240
  • Ghost 212

Note: Hemi-style cylinder heads (especially Ducar, Tillotson, and Ghost variants) may have a slightly offset or ported intake shape. While fitment is not an issue, minor port matching is recommended for maximum performance and seal.


Why Choose This Adapter?

Unlike low-cost cast aluminum intakes that compromise fitment and performance, the 448HWINT is machined for racers and tuners who demand precise fit and maximum flow. Whether you're building a mini bike, kart engine, or race-prepped clone, this intake is your solution for adapting high-performance Tillotson carburetors.


Order with Confidence

Built to EC Carburetors’ performance standards, this intake adapter ensures consistent fuel delivery, smooth acceleration, and reliable durability on the track or trail.

FAQ

What carburetors does this billet intake fit?

This intake is designed for Tillotson HW-Series carburetors with a 1.00" (25mm) bore. It may also work with similarly sized Tillotson(not HL or HR) carbs but check dimensions to ensure compatibility.


Will this fit my Predator 212 or 224 engine?

Yes, it fits Predator 212 (Hemi & Non-Hemi) and Predator 224 (Non-Hemi) engines. However, you may need to slightly port-match the intake if you're using a Hemi cylinder head for optimal flow.


Do I need to modify my engine head to install this?

Not usually. The intake is CNC-machined to fit the common D-shape intake port on GX200-style heads. If you're using a ported or Hemi head, minor port matching may be required for a perfect seal.


Does the intake come with everything I need for installation?

Yes. The kit includes:

  • CNC billet intake
  • Intake gasket
  • Pre-installed pulse fitting
  • Mounting bolts

You’ll need to supply your own Tillotson HW carburetor and carburetor boot (sold separately).


Is a pulse fitting necessary?

The pulse fitting is used to operate a fuel pump. If your setup requires external fuel delivery (e.g., high-performance or racing applications), the pulse fitting is extremely helpful—and it comes pre-installed.


Can I use this intake on a mini bike or race kart?

Absolutely. This billet intake is built for high-performance applications like mini bikes, go-karts, and racing clone engines. It's engineered for stability, airflow, and durability even under harsh conditions.
