Uh, an LS/VTEC setup isn't necessary "good for turbo." It depends on how you build it. The main problems associated with putting a VTEC h ead on a non-VTEC block come from the lack of a block girdle and VTEC oiling components. Granted, those can be added to a non-VTEC block, but they require a good amount of work and know-how in order to be done properly. If you want the strengths of an LS/VTEC setup, without the reliability issues, just get a GSR swap and put an LS crank and rods in it. You'll gain the LS stroke and torque while retaining the GSR girdle, oiling components, and reliability.

This is the right way to install a block girdle on a non-VTEC block:

As you can see, it's a fairly involved process, and unless you have some machining skills, it'll cost a lot in labor to have it done properly. That's why I suggest running a GSR block with an LS crank and rods, rather than putting a VTEC head on an LS block.
