Hi all, im looking for a place in Devon or Cornwall, Preferably Cornwall that could fit a 2.5l v6 calibra engine into a corsa and a 2l Turbo calibra engine into another corsa, and what sort of price am i looking at if i supply both cars/engines etc? how long does it take? Thanks in advance!

Thanks for that but im looking for a garage in Cornwall that could do it for me?
