hi can anyone help me (roughly) price how much my engine is going to cost to finish. the engine is out of 4x4 saph cosworth.
I'm not sure on the full specs be but so far I've got the following items
je pistons, arrow (copy) rods, gt30 turbo, tial 44mm external wastgate, hart inlet
this is how the engine stands at the min


basically it needs the head completely rebuilding to finish.
I want the head 500 spec, porting, new valves, valve guides, solid lifters, suitable cams, long studded (10), injectors, the lot basically

I'm no engine builder myself, nor do I know every component needed.

all help, advice and input would be greatly appreciated
