N/A 20B FC performance, power and cost
 
at this point it's an upcoming project, but I figured it would be cheaper than a turbo 20B by a good margin. Also I'm fairly sure there are more than a few of you guys that have them. And finally engine mounts; Anyone know where to get them from?
So, what kind of power can I start considering using various ports. and any other suggestions you all have for me.

There are some good posts if you search about N/A setups. In actuality, a healthy N/A setup isnt going to cost you much less at all than a turbo setup, when you start talking custom intakes, headers, ITBs, etc.. For just a generalization, ~320WHP with large streetport, custom header, stock intake. For much more than that you will need a specialized N/A intake, ITBs, etc. From there you can start looking toward ~375ish WHP, and for much more than that bridges and P-ports.

yea I was running the numbers and it looks like I could maybe get the swap down to around 8-10 K doing all my own work alot of cash but a lot less than 20K. Besides I only want 350 ish. street car mostly for around town and weekend cruising. oh and furthering the cause and supporting 20B swaps.

Anybody have some pics of an NA 20B build mostly exhaust and haltech installed in the cabin. I'm thinking Bridgeport for the build. 3in exhaust to duals.

We were already talking, so you know what i think you should do.. (pp!!!!) but i think that if you just wanted to keep it cost effective, mabey a bridge with a stock intake mani. That should be around the realm your looking for. Later down the lines mabey we can start talking about ITBs, and custom intakes.

also, something that i think needs a lot more experimentation, or at least open conversation, is a expansion chamber on the exhaust.
should be good for some mega ponies, and is probably what all those NA dragsters are doing that are making 9s on a 2 rotor with 420rwhp..
