some of you guys gave good points but the "thought" seems some what scattered.
I'll try to answer the questions.
1) VS does make more power... i don't care if you have a stock D series or modded B series. Every hp helps it's not spendy as other cone filters. I don't use it on the streets, only dyno session & at the track.
2) ITB can make great power BUT it's all about the collective built/combination of parts.
You simply can't say that ITB on any setup will make more power. Manytime mild setups like this one would probably make LESS overall powerband in return only yield 1-2whp at the very last 300-400rpms. So it's not worth it. Also keep i mind, they are not all that practical for the cars that drive to and from the drag strip. You can do it with some sort of filter cover over them. Tuning can be tricky (depending on the entire setup).
ITB are one of the last mods I would do if I was trying to squeeze every hp out of the engine. Quality ITB are not cheap.... used are $1200, new are +$1400.
For that money, more gains would be provided by custom sheet metal IM, CNC head, bad ass cams, stroker crank, custom header.
ITB are nice but not a "game-changer" for most setups. They just give you baller status points. jk.
3) IMHO WHP doesn't always mean fast.
You can invest $6k into a NA 250whp setup and run 11's, but spend $6K and also run 11's on a 400whp turbo setup. There's more to be said about it but i encourage you guys look into it some more, don't discount the learning curve of asking questions in your own words so you an a response that clicks with you.
4) honestly this setup could easily cost +5K, but it all depends on if your using new or used parts, and if your able to get some parts at dealer prices, if your able to get a great tuner, ect.
Think about this.

i added a ton of stuff in there that most people wouldn't consider as part of the "engine build"...
the key is the cam degreeing, tuning & engine asseymbly.
You can just copy the list but it doesn't mean the motor will run the same way.
does that make sense guys?
I don't know everything but i surround myself by people who know more than I do.
