Description
Dual Plenum fabrication kit for Toyota 3S-GTE – with CNC-machined flow rings
This version uses four CNC-machined flow rings at the plenum-to-runner connections instead of velocity stacks.
The two-chamber Dual Plenum design is intended to distribute charge air evenly between the cylinders. Air passes from the tapered tube through its flow slot into the plenum chamber, then through the flow rings and profiled runners to the engine intake ports.
The components are made from lightweight, strong, corrosion-resistant 6082 aluminium with good weldability. During fabrication, the tapered tube can be positioned to face forwards or backwards and to the right or left, to suit the engine bay and charge-pipe layout.
Included in the kit
- CNC-machined aluminium intake manifold flange for the 3S-GTE engine
- weld-together plenum chamber halves
- 4 CNC-machined flow rings
- 4 profiled runners
- tapered tube and flow-optimised end cap
- inlet cover plate
- flow-slot support bar
- detailed fabrication and welding instructions
Assembly
The kit is supplied as components for intake manifold fabrication. The parts are fitted to the planned assembly and welded using AC TIG.
