AUXILIARY DEVICES

• EXHAUST MANIFOLD

Branch Pipe Diameters 42.7φ
Branch Pipe Length #1. 470mm, #2. 460mm, #3. 350mm, #4. 360mm
Post collector φ 44.0mm diameter x 200mm long

The exhaust manifold does not incorporate an equal-length design. This will be one area where TOMEI POWERED will engineer, prototype and develop both equal-length and non-equal-length exhaust manifolds to optimize the engine’s performance.

• INTAKE MANIFOLD

The FA20 intake manifold features thicker walls and shorter ports (length of 335 mm) than the larger diameter and longer ports (length of 380 mm) of the EJ. The intake manifold port is 1 mm smaller in both height and width compared to the port on the cylinder head. This design reduces intake manifold revision.

The manifold is molded in a lightweight resin.
The diameter of the throttle body plate is 66 mm
