You can pretty much turbo any engine, although there will be hard limits to the amount of boost you can run. On pulp (e,g, 98Ron) you want your dynamic compression ratio to be around 7.5 for boost applications, go lower (e.g 6.5) if you intend running bland fuel . This can be achieved by increasing the clearance volume of the head, or if you are lucky .. by swapping the cam for a later inlet closing, preferably with higher lift: because of the later closing angle the low range torque will tail off a bit.
You will need to get control of the fueling and probably run at least about 5% CO to keep the engine cool. Spark will need to be looked at and so too will the squirters, fuel pump, etc
