if you are running less than 10 psi, just keep the stock b16a slugs and live a 10.2:1
and have more fun

B16 has a different rod length and deck height to compensate. All B-series pistons are interchangeable, except for the B20 pistons, but if you have another motor sleeved to 84mm you could run B20 pistons. Don't know why you'd do that, but you could.

Re: (1.7turbo)
hmm. i just dont personally get why you would goto all of the trouble to pull a motor apart and replaec the parts with stock ones. Just upgrade to forged parts while you are at it.
I just got my motor done like 10 minutes ago and i couldnt imagine going through the PITA to replace stock parts

That's interesting...yes.

Re: (brickonwheels)
lol. i didnt even think about that one.
true, for low boost setups the lower compression ratio is a good thing and even i have some laying around. I guess for a budget low power build up they would be fine

Re: (wantboost)
i woudlnt bother. i'd keep the b16 compressoin ratio. plenty of people have ran stock compression and still made power and lasted.
when it comes down to it. its about the tune. and how you drive you car.
i personally beat my car everywhere i go. needless to say nothing lasts long for me.

Re: (project dc2)
thanks for all the input guys. I was wondering this because i have a few empty b16 shortblocks laying around with no pistons or rods in them and a junkass turbo kit i can piece together.
One other question tho. Would the small end of the rod be too narrow if i did decide to do this? or would it even matter?

Re: (Mike@TSR)
i dont see why people replace with stock pistons either. 300 hp is 300 hp no matter what pistons u use. I say shoot for like 250-280 if your going stay stock and leave it there.

Re: (PhoenixTurboJesse)
good call. i didnt even think about the quench being better like that.
when you did it, did the pistons adapt to the rods ok? there wasnt too much piston/small end clearance?

Not sure..i had a machine shop do it...Just brough the a set of b16 pistons/rods and a set of pr4 pistons/rods and said swap the pistons rods

Re: LS Pistons in a b16??? (Mike@TSR)
Compression will be in the 8.x range. I did this a long time ago on my B16a also. Worked out well. I was a little ****, so i enlarged the valve reliefs before i installed them. Probably not necessary though.
