220 4-1 manifold and HJS HD 200Cell Catalyser
The 2bular 4-1 manifold + the HJS HD catalyser combine to release some serious gains in power AND torque. A tricky task as the standard torque figures were very good to start with.
The factory manifold design is very poor for a supercharged install and the stepped 2bular 4-1 manifold is a vast improvement. Adding a catalyser is always problematical to achieving best power but the big HJS HD version ensures you can meet all emissions tests and still gain +32bhp. NO OTHER CATALYSER WILL DO THE SAME JOB AS EFFICIENTLY AS THE HJS HD DESIGN.
https://www.rrrengineering.co.uk/ have been working with
to develop their stand-alone ECU for this install. Joe has had real success on track and this R&D will ensure a superb product to integrate with the 2bular exhausts for this car.
RECENT INDEPENDENT TESTING AGAINST OTHER 2ZR AFTERMARKET MANIFOLDS SHOWED THAT THE 2BULAR MANIFOLD GAVE BEST POWER AND TORQUE.
The first Lambda sensor is moved down the manifold and I supply a new Bosch sensor to protect your new HJS HD catalyser and ensure full engine performance.
