You got it all wrong, if you already have the b18a1 then ls/vtec would be you good option, BUT its considered by many people unreliable, I can't talk about reliability because I never built one and experienced it. It is also still more expensive then a boost setup. Your lookin at around 190 whp about $1200 not including the engine.
Boost is the best and defenitly the most reliable way of increasing your hp, and the b18a1 is perfect for it. Low compression engines can boost more on stock internals. A homemade turb kit can cost you less than $1000, depends on what your lookin for. You should be able to easily get 200 whp with a DSM intercooler and BOV, revhard manifold, hondata, and a T3 turbo at 7-9 psi.
I think you should just go and boost that shit because it's going to be cheaper, it'll last longer (depending on mileage), and will just make greater hp.

Holy shit, what the fuck, I don't remember writing that
