you'll need all new bearings and thrust washers(big end/mains/small end),new oil pump and possibly pick up pipe,gasket/seals set,new pistons and piston rings,defo have the head rebuilt by a pro,will stop most of the common cossie smoke probs,maybe have turbo rebuilt too.

obviously machine work on top of that too,but i did mine for less than £2000,using all genuine parts,some sourced cheap from GGR on ebay....big ends,small ends and mains cost me less than £100
