Well, you can just boost it up np, but for proper power and reliability low compression forged pistons, rods and ARP bolts are a good idea with a decent head gasket too. Coops went through more than one HG I seem to remember! You will also need a different MAP sensor, and at the minimum a 'log' manifold for the turbo to bolt onto, and a different downpipe. After that, an intercooler is a good idea with additional pipework for the setup. Car would need to be mapped as well, or get an off the shelf low or high boost ECU.
