for drag racing turbos are better, theres no question. lauch at 5,000 rpms, your at or near your peak tq and you just wail from there. superchargers work better for autoX and nitrous will aid 1/4 mile times. 1/4 mile is not about low end at all. we are tuning high rpm cars, not big blocks where low end power is awsome.

as foar as b18c5 vs b18c1... if you turbo a b18c5... you are throwing money away. it makes no sence to spend the exra money for a b18c5 thats tuned from the factor for NA power (higher compression and more valve overlap) if you are going to turbo it, where you want lower compression and less overlap. the b18c1 engine would be a much much better choice to turbo over a b18c5. if you want to BUILD a NA car, i'd still reccomend the b18c1 because you are going to need to replace alot of the internals anyways. if you want a motor and your not going to mess with it, only then would i see the b18c5 as a worthy investment.
