Just bought a mint calibra turbo with Very comprehensive full vauxhall service history. Been very well looked after by 3 previous owners. totally standard and even on original turbo with no problems whatso ever.
What is my best option before modifying? Thinking about getting the head skimmed and tested ( new valve guides and seats ), new gasket set, tappets and valves. already got a new turbo to go on it. Any other recommendations?? Was after a recon lump but apparantly unavailable
