VTT A90/A91 TOYOTA SUPRA SILICONE CHARGE PIPE KIT

VTT is proud to offer our Silicone Charge Pipe Kit for the Toyota A90/A91 Supra, designed to eliminate the restrictive, multi-connection factory charge pipe system and replace it with a simpler, stronger, high-flow solution built for increased boost and serious performance use.

The factory system utilizes multiple sections and connections between the turbocharger and throttle body, creating unnecessary potential failure points. The VTT system replaces that arrangement with a single 6-ply, heat-resistant, wire-reinforced silicone charge pipe rated to over 200 PSI.

The result is a dramatically simplified charge-air system with fewer potential boost-leak points, a FULL 3-inch flow path, excellent thermal isolation, and secure CNC-machined connections designed to stay in place under high boost.

Built for everything from stock-turbo street cars to high-horsepower A90/A91 Supra applications.

FEWER CONNECTIONS. FEWER FAILURE POINTS.

One of the biggest advantages of the VTT design is eliminating unnecessary connections in the factory charge-air system.

The factory arrangement utilizes four primary connections between the turbocharger and throttle body.

The VTT system reduces that to just:

TWO CONNECTIONS.

Every additional coupler and connection is another potential location for a boost leak or charge-pipe separation—particularly as boost pressure increases.

Our CNC-machined adapters feature barbed, multi-ridge retention surfaces designed to mechanically grip the reinforced silicone hose.

Combined with the supplied heavy-duty VTT T-bolt clamps, this creates an extremely secure connection designed to resist separation under high boost.

No more worrying about a charge-pipe connection blowing apart during a hard pull, at the track, or on the road.

6-PLY WIRE-REINFORCED SILICONE

This is not a basic silicone coupler being used as a charge pipe.

The VTT pipe utilizes 6-ply, heat-resistant, wire-reinforced silicone construction rated to over 200 PSI.

The internal reinforcement provides the strength required for serious boost pressure while helping prevent expansion, deformation, and collapse.

The silicone construction also provides another important advantage over conventional metal charge pipes:

THERMAL ISOLATION.

Aluminum and other metals are excellent conductors of heat. A metal charge pipe sitting inside a hot engine bay can readily absorb and transfer that heat.

Silicone is a much poorer thermal conductor, helping reduce conductive heat transfer into the charge-air path compared with a conventional metal pipe.

You get the strength required for high-boost use without replacing the factory system with another large piece of heat-soaked metal sitting inside the engine bay.

FULL 3″ FLOW PATH

Flow was a major consideration when designing the VTT system.

The hot-side connection begins at:

64mm / 2.50″ at the turbocharger outlet

It then immediately transitions to:

77mm / 3.00″

From there, the system maintains a:

FULL 3-INCH DIAMETER

all the way to the throttle-body inlet.

No unnecessary reductions. No undersized intermediate piping. No series of couplers and transitions.

Just a large, clean charge-air path from the turbocharger to the throttle body.

WHY SILICONE INSTEAD OF A MULTI-PIECE HARD PIPE?

There are other aftermarket charge-pipe options available for the A90/A91 Supra, but many address only part of the problem.

Some replace sections of the factory system with hard piping while continuing to rely on multiple silicone couplers and connections.

That still leaves you with:

• Multiple Potential Boost-Leak Points
• Multiple Clamped Connections
• Additional Opportunities for Couplers to Separate
• Metal Piping Exposed to Engine-Bay Heat
• More Components and Complexity Than Necessary

VTT took a different approach.

Rather than replacing a complicated factory system with another complicated multi-piece system, we designed a single reinforced silicone charge pipe that addresses the connection count, retention, flow, and thermal characteristics at the same time.

One pipe. Two primary connections. Full 3-inch flow.

Simple works.

METHANOL INJECTION READY

The VTT CNC-machined throttle-body adapter includes:

TWO 1/8″ NPT AUXILIARY PORTS

These can be utilized for methanol injection nozzles or other compatible pressure/boost accessories.

No drilling or modification of the charge pipe is required.

If the ports are not being used, they can simply remain plugged.

PRECISION CNC-MACHINED ADAPTERS

The VTT system includes purpose-built CNC-machined adapters for the critical factory connection points and sensors.

These include dedicated adapters for:

• Turbocharger Outlet
• Throttle-Body Inlet
• MAP Sensor
• Temperature Probe

This allows the VTT system to integrate cleanly with the factory engine-management hardware while eliminating the unnecessary complexity of the original charge-pipe assembly.

WHAT’S INCLUDED

• 1 VTT 6-Ply Wire-Reinforced Silicone Hot-Side Charge Pipe
• 2 VTT-Branded CNC MAP Sensor / Temperature Probe Adapters
• 2 VTT-Branded CNC Turbocharger Outlet / Throttle-Body Adapters
• 2 VTT-Branded Heavy-Duty T-Bolt Clamps
• 2 Integrated 1/8″ NPT Methanol/Auxiliary Ports in the Throttle-Body Flange

Everything required to replace the factory charge-pipe assembly is included.

INSTALLATION

Installation is straightforward and requires no permanent modification to the vehicle.

For an experienced installer or someone who has previously removed the factory charge-pipe system, installation can generally be completed in approximately:

30–45 MINUTES

For someone working on the vehicle for the first time, we recommend allowing approximately:

1 HOUR

FITMENT

Designed for:

Toyota A90 Supra
Toyota A91 Supra

Compatible with the aftermarket intake manifolds we have tested.

IMPORTANT AFTERMARKET MANIFOLD NOTE

Some aftermarket intake manifolds may require minor trimming of the 3″ silicone end due to dimensional differences between manifold designs.

This is normal and allows the silicone pipe to be adjusted for proper fitment with different aftermarket manifold configurations.

THE VTT DIFFERENCE

The VTT A90/A91 Supra Silicone Charge Pipe Kit isn’t simply another replacement for the factory charge pipe.

We looked at the entire system and addressed the weaknesses at their source.

Instead of multiple hard pipes, multiple silicone couplers, and multiple potential failure points, VTT gives you a single 6-ply wire-reinforced silicone charge pipe rated to over 200 PSI, secure CNC-machined barbed adapters, heavy-duty T-bolt clamps, a full 3-inch charge-air path, integrated methanol ports, and reduced conductive heat transfer compared with conventional metal piping.

All in a simple package designed specifically around the A90/A91 Supra engine bay.

Fewer connections. Fewer potential boost leaks. Less complexity. Full 3″ flow. Built for boost.
