You won't want steel rods and crank etc for 200bhp - I priced some up and the build worked out at over £4k! for a 1900 CVH.

Basic spec of mine is
CVH 1740 bore
Accralite forged pistons (£25 more each than mahles - which are OE anyway!)
Lightened and balanced
Stage 3 head
Piper 285t2 cam (kent or 285t is propably better though for mild use)

Running 12.5psi, its putting out 187bhp and 183lb/ft torque.
BUT that is with a failing ECU which is retarding the timing also! So with 15-16psi and a sorted ECU I would hope for a true 205-210bhp and around 195-200lb/ft torque. Just some thoughts for you - hope it helps

BTW - with this spec stick to a stage 2 hybrid don't go for the stage 3 hyrbid - it is too big gives tonnes of lag!
