I'm stripping down my series 1 and fully restoring the shell, the cars just gone round the clock so i want to do the engine too. Its got full service history, no engine mods but obviously its well tired at this point.

What sort of cost am i looking at for a full engine rebuild either standard or looking for 150 - 200 bhp retaining as much reliabiliy as possible?

Also who would you choose/recomend for the engine work?

Cheers guys
