Questions on Port & Polishing a b16a

I went to portflow and looked through some stuff and was kind of putting together a wish list for someday in the near or shall we say far future and i was just wondering if anyone could tell me how much hp they think i would be making, and what major differences would i see in the engine?
My List-

  1. Standard Honda headwork=$900
  2. Skunk 2 Inatke Manifold=$265
  3. Skunk 2 Cam Gears=$210
  4. Portflow Inner Valve Springs=$80
  5. ITR Outer Springs=$80
    -Grand Total=$1,535
    Sorry if some of this seems wrong but I’m kind of inexpirienced in the headwork dapartment and if i need more stuff than that will someone let me know.

how much power you’ll make will depend on what kind of compression you run, what cams you run, as well as quite a few other factors.

one comment, $210 for skunk2 cam gears is a little expensive. I’ve seen them for $180. And still i don’t see cam gears being worth that much unless they are some super precise ones like toda or jun… but maybe i’m just a cheap bastard.

cool thanks for the reply. Could i use my stock b16 pistons and cams or would it be beter to buy those to.

you could use your b16 pistons and cams to make it run. if you want to use all the money you spent on that, you’d want to get some higher CR pistons like ctr pistons or the such, as well as some hotter cams, skunk2 stage 2, toda B, etc. etc.

yeah, what he said. your stock parts will work fine, no problems there… you just won’t be getting full advantage of the port/polish. But thats how it is with every mod. you won’t get full advantage of cams if you don’t have i/h/e, you won’t get full advantage of i/h/e if you don’t have cams, you won’t get full advantage of high compression and cams without a port/polish, you won’t get full advantage of all that stuff without a better intake manifold… your engine is a big air pump. It sucks it in, and pumps it out. Your goal is to make it do so very efficiently and push through as much air as possible in a give amount of time… so basically every component matters. Once you upgrade the weakest link, a new part becomes the weakest link… and it continues pretty much forever.

another quick couple comments.

you will get almost zero gain from the cam gears until you get cams. So, if you get the pp, hold off on the cam gears till you get cams. Or just put them on and don’t worry about tuning until you get some cams.

also, running stiffer springs w/o cams may not be a good idea. I was talking with dan about this a little while ago. I was trying to decide what springs to put in my b17a (eventhough it would be a long time till i could afford cams). He reminded me that a stiffer spring on a cam that doesn’t need it will give you a little parasitic loss in power (because the spring pushes harder on the cam lobes than is necessary). This isn’t a big factor, so its not a big deal… but i figured i’d mention it because i’d never thought about it like that before.
