Why Choose a Schedule 40 Twin Scroll Manifold?

Because cheap manifolds crack.
Cheap manifolds warp.
Cheap manifolds ruin your day.

This one?
It’s built like a tank.

Benefits:

• Twin-scroll T4 flange → Faster spool, better boost control, more torque

• Schedule 40 thick-wall tubing → Crack-resistant even under extreme heat

• Optimized runner flow → Maximum exhaust velocity into the turbo

• Supports big-frame single turbos

• Perfect for high-horsepower NA-T conversions

• Stronger welds, smoother transitions, better performance

If you want your 2JZ-GE to survive — and thrive — under boost, this is how you do it.

SCHEDULE 40 TURBO CONVERSION MANIFOLD FOR TOYOTA SUPRA MK4(JZA80) 3.0L 2JZ-GE NATURALLY ASPIRATED

A performance tuned turbo manifold ensures quicker and smoother flow of exhaust air to increase engine output and efficiency. Vacating exhaust air faster allows more intake air into engine cylinders for better combustion.

Key Features

🔥 T4 Twin-Scroll Turbo Flange

For turbos that actually spool instead of coughing their way to 5 PSI.

🔥 Schedule 40 Thick-Wall Steel

Far superior to thin manifolds that crack under real boost.

🔥 TIG-Welded Construction

Strong, clean, consistent welds built for track, drift, and drag abuse.

🔥 External Wastegate Compatibility

Stable boost control and the option for an ear-splitting screamer pipe.

🔥 High-Flow Runner Design

Optimized for even pulse separation — exactly what twin-scroll turbos want.

Moreover, having separate ports and tube paths for each cylinder eliminates interference between exhaust pulses and thus reduces backpressure. Designed for turbo conversion (NA-T) on Toyota/Lexus 3.0L naturally aspirated 2JZ-GE motors, this product features an equal length runner design that is common with contemporary high performance turbo manifolds and separate exhaust gas outlets for twin scroll turbos.

Vehicle-Specific Fitment

This heavy-duty T4 twin-scroll manifold fits all 2JZ-GE configurations:

Toyota

• Supra MK4 (1993–1998 NA 2JZ-GE)
  Perfect for NA-T builds without paying GTE tax.

Lexus

• GS300 (1993–2005)
  Ideal for luxury turbo sleeper builds.

Other 2JZ-GE Platforms

Also works with:

• SC300 (1992–2000)

• IS300 (2001–2005)

• Aristo NA models

• 2JZ swap chassis (S13/S14, BMW, Volvo, etc.)

If your engine is a 2JZ-GE, this manifold bolts up.

The piping is constructed from austenitic T304 stainless steel Schedule 40 tubes with patented craftsmanship for extraordinary strength. It is precisely aligned to maintain smooth paths for non-restricted flow. TIG welded at all joints, it also combines a cracking and corrosion resistant surface and an obstacle free internal wall.

Perfect For Builds Like…

• NA-T Supra conversions

• GS300 sleeper turbos

• IS300 drift cars with twin-scroll setups

• SC300 single-turbo builds

• 500–1,000+ HP projects

• Anyone who wants instant response AND massive top-end power

Premium materials and top-notch craftsmanship make this manifold an ideal upgrade from its ordinary stainless steel piping counterpart for only those top class racing engines. IMPORTANT: This product is for 3.0L 2JZ-GE naturally aspirated motor only.
