Pull the engine and bore it just a bit (not too much or you will kill the sleeve) most shops can bore and hone this block in about an hour at minimal cost.
Keep the stock crank and rods, change the pistons to match the new cylinder size (try to use alu forged if you can, if you go cheap use a heavy oil).
Rebuild the head (valves, springs retainers, seals, and guides if you can) and just polish a bit with a dremel (don't dare do more than smooth and polish), this head can't really be ported.
Put the head back on using new hardware and a decent head gasket.
Install Hahn Racing portfueler on engine and change fuel pump and regulator (Hahn can help if you are not familiar with this process).
Install a chinese turbo kit (toss the bov and get a good one if you can and get a boost controller if you can).
If you experience fuel cut get a fuel cut defender (cheap just get one anyway).
Once it is ready to rock use a laptop to adjust the port fueler map (installing a wideband o2 sensor and display very very very highly recommended).
