DB2, DB2/4, DB2/4 MK2 and DB MKIII
The Ultimate
Engine power can be increased beyond that of the Fast Road engine, but it will however, be at the expense of flexibility and general refinement. Aspects of engine development include gas flowing and blue printing of the cylinder head and block assemblies, the use of a fully mapped ignition system and the use of high lift racing camshafts. Each project really needs to be discussed in detail before a final specification can be finalised.
In all other respects, the complimentary transmission, brake and suspension modifications that would be recommended are those for the fast road engine, as detailed here.
