upgrade represent a progression to a more serious level of engine
tune & specification, because of this more care and attention
to detail is required when building such an engine. The MBE9A4 Ecu
has been programmed & is ready to use, however we would recommend
a mapping session to fine-tune the engine.
kit is the first one to incorporate Cylinder head work, which includes
changes of valves & valve guides The cylinder head & port
work is done by hand with race valves of 33mm inlet & 29mm exhaust.
also replaces the standard rods with steel ones to allow the kit

should be upgraded, please see optional
extras for information on the type of regulator available.
building an engine of this level of tune we would recommend the
use of a Dry
sump system for added protection, unless class rules prohibit
All our kits have been developed using exhaust manifold designs that have been dyno tested and developed by ourselves. In order to achieve the optimum performance from your kit, you will need to have an exhaust manifold made to our design. When you purchase the kit, this information will be included.
