I have just finished the assembly of Brian’s engine, aka the 2012 engine. As the deadline approached and some pieces became unavailable (crankshaft issues forced the changes), the planned developments changed and Brian’s engine now includes

JE higher compression pistons,
New redesigned cylinder liners with revised tolerances.
Modified porting to inlet & exhaust
Recut & re-profiled valve seats

Revised oil circuits
Greater oil capacity by fitting M. Joel Brunel’s double sump (modified to take O ring seals & filter plate)
