Description
WRC-Style DIY Dual Plenum Intake Manifold Kit for Toyota Celica & MR2
MW Steel’s dual-plenum intake manifold delivers consistent pressure and flow to all cylinders, enabling maximum engine power and torque output and longevity. The consistency of pressure and flow is based on the Swiss physicist Bernoulli’s law , according to which pressure decreases in a narrowing pipe while the flow rate of liquids and gases increases. It is easier to tune the engine when all cylinders have consistent air-fuel ratios and can be set to the same optimal ignition timing. The engine operates harmoniously as a whole, making it easier to avoid knocking and other adverse effects that reduce engine reliability and lifespan.
The high-quality components of the DIY DP intake manifold kit are made of lightweight, strong, corrosion-resistant, and highly machinable and weldable 6082 aluminum, which is 5 times stronger than pure aluminum.
The conical tube can be positioned flexibly in the pressure housing depending on the inlet side of the supercharger (front or rear) and to adapt to the space in the engine room (left or right).
The DIY Build Kit includes the following components for fabricating a WRC-style Dual Plenum intake manifold for the Toyota Celica / MR2 3S-GTE Gen 2 engine:
-
- Precision CNC-machined, engine-specific aluminum intake manifold flange
- weldable boost pressure housing halves for secondary plenum
- 4 aluminum velocity stacks designed to improve airflow inside the plenum chamber
- 4 precision-profiled intake runners for installation between the intake manifold flange and the plenum chamber
- conical pipe for primary plenum
- Flow-optimized end cup and inlet side cover plate for the narrow end of the conical pipe
- Cone pipe flow slot support bar to prevent slot expansion under high pressures
- detailed construction and welding instructions
The throttle flange is available for purchase separately from our online store. See the section “Aluminum parts / DBW throttle flanges” and choose the most suitable option.
Note! The components of the building kit are welded with AC-TIG.
