what are the limits of phk (b20z2) pistons
The limiting factor is going to be whether or not there's any headwork, or additional compression added via other methods (milling the block/head, thinner head gasket, etc etc) and what your other supporting components are (bolt-ons etc).

hey guyz..recently purchased a complete b20z shortblock and was gonna slap my b16 head on..has valvetrain done with sk2s2 cams..read that i will needa open up the valve relievies and will do so if needed..wanna run at least a 2layer hg and my arp rodbolts r on the way..anybody has a similar setup??wanna upgrade pistons bcuz of compression and valve clearance issues but wanna stay stock as its cheaper for me(y i bought a shortblock instead of a bare block)..lmk ASAP guyz..
trust me..i searched..especially wit all these "hardcore og" getn on everybodies case..just cant find anything useful enough..seen pro2s on stock b20 block..but doesnt mean anything to me..i needa know wat exactly needs to be done to work or something close..followed up on a few threads but it just leads to flamers tellin the op that he NEEDS to switch pistons so that he will have the needed compression to run the necessary cams and blah blah etc....ya feel..thnx.
The kid who claimed Pro2 is full of ****.
OEM B20 piston, OEM cam. Simple.
If you can't afford to build the block, how are you gonna afford it when you blow it once you get it running?

i can but i rather not..i just want peeps that have done s2s2 on stock b20z block to chime in..i can just easily swap in some gsr cams i have sittin in the garage but y..i just want that little edge on peeps wit similar setup running oem cams hypothetically speaking if both motors was as equally healthy/strong..thnx
"Peeps" are not going to "chime in" because "peeps" have not done it. You can't. Again, if you cannot afford a rebuild, then go with the safe route. If you're wanting to go fast without spending money, Honda's are not for you. Look into a small block Chevrolet.
lol..its ok..domestic ftl..as for a rebuild, there is a difference between cant and rather not..and never did i say i cant..i just said its cheaper for me and that does not mean im building a cheap block..its just stock piston and better suited for my application..rs piston and ycp are ~$320..thats affordable..ill give it a few days n see if anybody says anything..if not, i AM prepared to buy the necessary piston set..but still "RATHER NOT" and diffenitely not goin the safe route..i rather make it work..the goal is to keep my cams and beat some boltons, slight modified v8s..lol..i can do that already but need it to be more often..haha..i do lose even tho vtak never loses
..thnx
..thnx
