vtec,boost or both

i have a pretty stock 92 integra gs. It has the 1.8 non-vtec and i wanna boost the power a little more. My friend just recently bought a 92 GS-R (with the vtec of course) and its all sorts of hella faster than mine. so to help even the competition i was thinkin of putting a vtec head and computer system in mine. Then to help un-even the competition i was thinking of puttin a turbo on it also. He then told me that it was stupid to turbo a vtec because the turbo wont help much. so i was wondering if any of u smart mechanics with integras could help me on the matter.
