Elise 1.6 1ZR-FAE Manifold & Catalyser
The OEM manifold is a short, small-bore 4-1 design - not the best for performance - and the 1ZR-FAE motor does need a bit more grunt.
The 2bular 4-2-1 manifold, with its bigger-bore primaries and matched secondaries combined with the 121mm diameter HJS Directional 200cell Sports Catalyser gives a good increase in power and torque - minimum 15bhp and 12ft/lbs torque over the OEM figures. The motor loses nothing at lower revs and from 3000rpm onwards the difference is remarkable. The torque increase is especially welcome on the road.
With the longer pipework, I've had to move the 1st Lambda sensor downstream to the inlet cone on the HJS Catalyser. A wiring extension for the re-located sensor is supplied. Gasket between manifold and cylinder head is also supplied.
2bular build-quality features a 10mm head flange for strength with the longer manifold, with fabricated/TIG-welded merge collectors.
