So I have a blown b16a2 from my 2000 si in my garage and Im thinking about just using that for my next endeavor instead of buying, ohhh lets say a B18C. I either want to go all motor with ITB's or build it for a jackson racing supercharger. Now, over the past couple months, I've been doing alot of research and asking alot of questions, which has resulted in me learning ALOT! BUT, there are still things that I am not completely sure about. For instance, lets start with bore. The b16 has a stock bore of ...? and buy boring it out to ... that does what? The word displacement comes to mind here. And by increasing the displacement I increase horsepower and torque, correct? What Im getting at is I want to bore it out to 1.8L. Boring it out to ...mm will make it a 1.8L engine? Now I know youre thinking "oh but wait! youre gonna make youre cylinder walls to thin." Dont fret, I already plan on getting the block completely sleeved. Now lets talk about stroke. Changing the crankshaft so it has a longer stroke does what? Increase displacement? By making the stroke longer you are physically moving the piston higher up and farther down in the cylinder? So this should also increase the compression ratio? Also, on a b16 do I even need to bother messing with the crank aside from replacing it with a stronger lighter one? Moving on... So lets say I go with the supercharger. Do I just run the supercharger on the stock compression ratio pistons or do I lower the compression? If I do need to lower the compression what compression ratio piston do I need? OR, can I actually run a slightly high compression piston with the supercharger? I dont know you tell me.Now keep in mind everything in this engine will be forged. So strength and durability wont be an issue. Now to the ITB's. Ive heard lots of different opinions and stories about these things. Great for mid-range and top end but not so great for low-end and drivability. Drivability im not terribly worried about because I dont plan on using the car as a daily driver but I do want to be able to drive it on the weekends without it stalling out on me and just generally taking a shit on itself. So what do you guys know about ITB's. When they're good, when they're not good, and what kind of internal set-up you need to be running for these to be effective. I know this was a long post but I appreciate you taking the time out to help out a fellow enthusiast. Just remember you had to learn what you know at some point from someone. So, if youre gonna rag on me for being a "noob" and not being a master automotive technician then dont waste your time here. For those of you who want to help understand this...I am a Marine. In the Marine Corps we have a saying. Break it down Barney Style. So if you could break things down Barney style for me that would be much appreciated. Thanks alot guys.
