Vauxhall 2.0L XE Multi-throttle & Carburettor kits 2nd upgrade
For 2.0 Litre 16V XE & LN Engine
Exhaust Manifold type needed to run with this kit C-2.0L-XE

This kit is a competition progression from the first upgrade.The torque and power increases are quite substantial. The torque spread is very wide & flat thus allowing the driveability to be maintained. The MBE Ecu comes programmed & ready to run.

2L Pistons
Camshafts & valve train components The power increase has been achieved by an increase in lift on the cams to generate the extra power, with only a small increase in duration. For this reason we use double valve springs to take the extra lift, with a change from hydraulic to solid followers thus necessitating in a change of platforms & caps.
For the Multi-throttle kits, it will be necessary to upgrade the injectors to the smaller high flow peco injectors INJ-480P along with changing the fuel rail. Also the fuel regulator should be upgraded, please see the Recommended options section of the Multi-throttle Basic Kit.

Once you have progressed to this level of upgrade, it would be worthwhile to consider cylinder head work and inlet manifold porting to increase the bhp by a additional 20bhp. This would include a changing the valves to wasted stem type along with bronze valve guides.
Cylinder headwork Valves & Bronze guides
Additionally you may wish to consider the installation of a dry sump system for added protection, unless your class rules prevent it.
