piston questions
so when i get paid i'm gonna look for some pistons, really haven't looked into internals before so just woundering what brands are decent and aren't too much money(i've heard bout vitaras, just want to know my other options)? I'm looking to spend around $200-$250 or so. also since i have a sohc zc vtec motor what pistons should i look for that would fit my motor (d16z6? d16y8? etc)? Last question, since #3 is the one giving me problems, i'm going to rehone and i'm guessing i should do it to all 4, but after rehoneing, should i look for stock bore pistons? or something a little over? i've already tried asking johnny these questions and he said to shoot these to everyone at hmt, so answer up
thanks in advance

Re: piston questions
rehone != rebore
i sure hope you wouldn't need oversized after just a simple rehone. get a caliper and measure up cowboy. a little over is probably going to be 75.5mm and that .5mm makes a damn big difference when clearences are in the tens of thousands of an inch on some things. id imagine just make sure your gap is good to go on your rings when you install and use standard bore pistons. building a motor is different every time you do one, so you might want to do some more reading.

Re: piston questions
for what its worth, i've got a z6 block im tearin down as soon as finals start, and i'm going to go ahead and do .5mm over just to start fresh. of course it might see some decent boost if all goes well. haven't even looked at compression or anything yet, but the clock says 210k so im bettin it needs it.
