Elise S 2ZR-FE 4-1 Manifold & HJS HD Catalyser
The supercharged 1.8Ltr 2ZR uses the same OEM manifold as the N/A 1.6Ltr 1ZR - that's not ideal. Take a look at the pic of that manifold alongside the new 2bular design. The supercharged car needs that larger-bore 4-1 to release some stunning gains over standard. Everything just works so much better - the engine operating temperature comes down and the power and torque figures go up!
The new 2bular 4-1 manifold uses our new 2-step / 3-stage design to maximise power AND torque. We always use proper merge-collectors to manage the gas-flow, and decrease any turbulence - all hand-fabricated/TIG-welded - it's a quality product with excellent performance gains. Recent dyno work at Komo-tec showed a 25whp gain - see graph. Komo-tec will have a specific tune for this 2bular install.
The HJS HD 200cell Sports Cat is perfect for a road-going sportscar looking to meet any emissions tests and still improve gas-flow and performance.
The 1st Lambda sensor is moved downstream to the catalyser and a wiring extension is supplied with the manifold. A new main gasket is also supplied.
