Has anyone upgrades their pistons/rods and changed their compression ratio? Just wondering if anyone would like to share

Well, yeah. Look in the Naturally Aspirated section of this forum for lots of guys have upped their C/R while if you look in the Forced Induction section lots of guys have decreased their C/R.

Ahh that does make sence to decrease it...

Soo when I do get around in getting different pistons and rods that decrease the compression ratio and when i change the cam shaft I won't have to worry about claying it then

No need to lower the compression for a straight Y8/Y7 mini-me unless you're adding boost.

Decreasing the C/R by swapping pistons generally means you'll be using pistons with a dish so the likelihood of smacking a valve is low. Now unless you're using some bad ass cam you shouldn't have to clay. But you can always be better safe than sorry.

If i do add boost down the road what should the compression be?

Im just courious, what did other drivers do, like whats their compression settings

they usually search.

but you can go 8:5:1 or 9:1

do a search for vitara and thank me later.
