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

vitaras and fjt rods.

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.

giving you problems how? get out the calipers and do a piston vs wall sizing.

calipers O0 ruler ftw

seriously i would never use calipers on engines, only for a quick reference check ,not accurate enough i would use a good pair of mics/ dial bore gauge or intramics

Honda cylinders are known for being egg shaped from the factory, so IMO I'd go oversized

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.

Re: piston questions
 

burning oil pretty bad, compression is lower in #3 then the others....in oct i had a compression test done, 200, 200, 165, 200.....i've beat on it enough that i've probably made it worse over the past 6 months...would the vitaras work fine with stock rods? i'm only shooting for 200-220 whp

Re: piston questions
 

lower ( like 7.5:1-low 8:1) compression

fjt rods ftw
