just wanna know if i have to modified my engine, if i put the turbo kit on it?

i have a 95 prelude with a 92 h22a vtec. now, the engine has 158000 miles on it, i want to change valves, pistons, manifold, rods, cam gears and other internals because i want to get a turbo, but i want my engine to be right then to blow it. now, being at the high milage that the engine is at, is it worht it to put all these new internal parts in or just get a new engine period and then put them on?

I want more power in my 2005 Honda accord. It has a 2.0lt JDM K20a engine. What are my options to get more out of this engine besides swaping engines.

do you think is a good idea to replace my Honda CRV 2004 2.4 I-Vtech with 2007 Acura RDX 2.3L turbocharge Engine. I want to improve my performance and acceleration too or what about the Honda S2000 engine is that also a good idea but the S2000 engine as manual my CRV is automatic so please let me know thank you.
