how much would it cost to completely rebuild the head and bottom end of a m20b25 engine and anyone know any recommended companies?

New engine would be loads cheaper than rebuilding the whole thing... Just get one from a good know runner and switch it over yourself. :D

At least £1500,but better to budget for £2500.

To some extent it depends on how much work you can do yourself.

I like the m20 but wouldn't spend 3-4k on one.

Instead of messing about just buy a good one from a known seller
