Honestly, your gunna have a tough time going with a VTEC setup if your on a budget.

I was looking into similar things, and if you want everything done right, ls/vtec, b20/vtec, gsr, or b16 are all gunna be a tad bit expesive. The cheapest "full swap" would be an ls swap with a vtec, and even then to go ls/vtec SAFELY, your gunna be up near a b16 or gsr price.

Truth hurts. If you know how to do all the machine work on a ls/vtec, do that. otherwise. Hello non-vtec!
