Why Turbo Your 4A-GE?

Because:

• NA 4A-GE = fun

• Turbo 4A-GE = religious experience

This manifold transforms your engine from “rev-happy classic” to “rev-happy, tire-melting boost machine.”

With this manifold, you get:

• T25 turbo compatibility for quick spool

• Smooth, high-flow stainless runners

• Lightweight but durable construction

• Better boost response across the entire RPM range

• Reliable welds that survive heat cycles

• A perfect fit for most 4A-GE RWD and mid-engine setups

Your 4A-GE deserves boost. This manifold makes it easy.

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. 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.

Key Features

🔥 T25 Turbo Flange

Perfect for:

• Garrett T25

• GT25/GT28

• Small-frame quick-spool turbos

• Street/track builds that value response over lag

🔥 Stainless Steel Construction

Heat-resistant, warp-resistant, and an upgrade over tired OEM cast parts.

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.

🔥 TIG-Welded Runners

Strong welds built for:

• High heat

• Repeated boost

• Spirited AE86 driving

• Spirited AW11 chaos

🔥 Smooth Exhaust Flow

Optimized runner geometry for fast spool and enjoyable midrange torque.

🔥 Bolt-On Fit for 4A-GE

No funky angles, no weird spacing, no headache.
Just bolt it on and go make spool noises.

This allows for a much smoother flow of exhaust gas to the turbo.
