Hi mate, I guess your the guy who PM'd me on 306.net. Cool project.
In my opinion it might be cheaper to swap to the 2.2 HDi 8v (DW12 engine) as apparently that'll see 250bhp on the standard internals whereas the DW10 is said to be limited at about 230bhp before the rods get snappy
Custom forged con rods will cost £500-£1000 at a guess, the pistons will be about double that. Diesel pistons are especially complicated as they have the "heron bowl" in the top that either needs to be cast in or would be incredibly difficult to machine out.
For con rods you may be best to measure up the con rod length and gudgeon pin diameter and see if there is something existing in the right size for either the GTi6 or the s16 as they both use the same big end bearing size ad the HDi.
