Elise SC 2ZZ-GE 45mm 4-1 manifold & HJS HD Catalyser
Designed specifically for the characteristics of the MP45 supercharger, this stepped manifold (header) design uses 3 different diameters in its layout. I use a laser-cut, 10mm thick stainless steel head flange with expansion slots to control warpage but still give the required extra rigidity with the longer pipework.
I always use hand fabricated, high-quality merged collectors on my manifolds - (no squashed pieces of tin). They are fully TIG-welded, keep turbulence low and enhance the gas-flow characteristics. No slip-ons, no springs - no leaks! The T4 ECU does not like leaky manifolds!
All the pipe sizes are chosen for the Elise SC systems that 2bular specifically manufacture for this motor. No other aftermarket tuner/supplier offers this degree of customisation.
IF YOU USE THE SAME BIG-BORE MANIFOLD (HEADER) AND SYSTEM AS THE MP62 CARS, YOU LOSE BOOST - AND THAT RESULTS IN LOSS OF POWER/TORQUE. ONLY 2BULAR BUILD DIFFERENT MANIFOLDS FOR THE DIFFERENT SUPERCHARGERS.
Catalyser: In keeping with the renowned 2bular quality, I use the 200cell HJS HD catalyser. Made in Germany, it is recognised as the best catalyser in the World. Used as OEM supplier to all the Supercar manufacturers. It's big - 130mm diameter - it has heavy coatings of the precious metals used in catalysers and it means you will meet any emissions tests. The Lotus ECU accepts it - with no CEL's. Don't settle for less.
I SUPPLY A NEW 1ST LAMBDA SENSOR WITH YOUR NEW HJS HD CATALYSER. THE SAME BOSCH SENSOR AS USED BY THE FACTORY.
