You havealmost the same engine and drive train as me.
Differences are I have:

Peco injectors.
Helix paddle clutch.
SX FPR.
Standard early (light) crank.
Quaife ATB LSD.
MBE 967E ecu.
Firdenza 3kg aluminium flywheel
Arrow conrods.

Mine makes 262bhp and 179lb tourqe (as measured on Track and Road rollers).

Takes lots of money to build one of these doesn't it.

by the way.... the 2007 engine is for sale if anybody might be interested? it is fully rebuild (i had plans to make this engine even more powerful, but changed my mind and started on another engine with a totally different concept.
it had 3000km before rebuild, everything is like new.
