It makes the displacement of the engine larger.
No offense but you should do some research. That mod is done further down the road for most people. Think about waht you want to do in the future. If you're going n/a then go for a bore. But you should get cai/header/catback first at least. Try the search button, all i gots to say

I have my car bored to 78mm as opposed to stock 75mm, the owner of the car before me, who is a good friend of mine did the work. I have no idea how much is costs but it does give a noticable difference in performance, i would go for some other mod if i was you tho.
You don't usually get a substantial amount of displacement from boring. But you do get nice perfectly round holes for your perfectly round new pistons. Better seal for the rings and the option of running more performance oriented pistons for higher compression.
I can't remember the equation. Is it Bore2 X Stroke X .7854 (????) X number of cylinders??? I gotta 
that crap. I can't remember. If that's the number then you are pushing about 1.7 liters...did you just use stock D17 pistons? Something else? I was kinda curiuos about that because the D series cylinder liners are kinda' thin. But if it works that's cool.

Sounds expensive it take it you would need new pistons then right?
oh yeah sorry by the way i forgot to mention i have all that s**t already I/H/E Cam gear and Cams pulleys hi flow cat 8lb flywheel stage 3 clutch, I don't wanna go turbo though only NA, is it possible to bore it out so it would be displacing 1.8 ltres to is that too much, I have a 1.6 SOHC vtec, please don't crack on me i just wanna know. i've read threads where ppl wanna know a lil' info about a subject and just get shitted on by everybody
call altered atmosphere......they're right down the road. 1000 shops within an hour driving from DC

you would have to stroke the motor also to get 1.8 liters. the formula for displacment is simply bore x stroke.

2 things, if the motor is really bored out, you have to have aftermarket pistons, or he lied to you. your stockers are 75mm wide, and if the cylinders are 78mm wide, theres no way your engine runs. and even with aftermarket pisons, its a really bad idea to boost an unsleeved motor because the d series sleeves are already weak enough, and boring them out weakened them more.
One millimeter is huge when boring an engine and if you bore too much you'll likely burn a hole in your engine. This modification is expensive and whether or not you should undertake it varies very much on the engine you have.
thanks everybody, iilcon you know about Alterted atomsphere? I had them do all my work the just got real expensive so i started going elsewhere, guess i'll give them a call thnaks every one
