First and formost find out what work was done to the engine by the previous owner.You will be wasting a lot of time,money and maybe even a strong engine if you try to add a turbo to you obvioudsly n/a tuned engine.save your self a BIG headace and fin out what was done.High compression,cams tuned for n/a, and agressive fuel and timing maps are not good for forced induction.Sure you can run high compression and a turbo but trust me you don't wan't to for a street set-up.I'm runing 10.2:1 compression and it's hard enough to tune let alone 11.0:1 or even 11.5:1 compression.When it comes to boost and high compression unless you really know what your doing and you have a programable engine management system don't even waste your time.
I recoment that you
A) find out what engine work was done by the previous owner
B) read up on how turbo's work,tuning of turbo's,engine dynamics,and probably the basics of how engine's work (esp the honda engine when it comes to modifying).
And please don'r go out and buy a turbo kit because somebody recomends it UNTIL you know what you're dealing with.
