Suggestions for Rings?
I have a 2000 SI and am getting terrible blow-by. you guys have any suggestions for piston rings? I just have bolt-ons- nothing crazy. if so is it easier to leave the motor in the car and just pull the head and drop the pan?

It is easy to pull the head and drop the pan, i have done it a couple times on some cars. Just have to be careful not to let the rod bolts hit the crank and scuff the journals.
If you have stock bore and stock pistons and all that just run a set of OEM rings. IMO if your going to have it apart throw a new set of p30's in there w/ rings and enjoy some added power.

hastings, NPR/Nippon are both cheap and good. OEM rings are made by a Japanese company that merged with Hastings.
You should use a ball hone and hone the walls prior to putting new rings in. It's the only way to get proper ring break in. The little ridges will file the rings down and make a better seal than even the best rings could without it.

You're going to hone the cylinder walls while the crank is still in the block?I know it's possible, but you could end up w/MUCH WORSE problems than blow-by......

Re: Suggestions for Rings?
is it recomended to replace the head gasket everytime you pull the head? I replaced all the gaskets and seals and few months back when i rebuilt the head, i know im an ******* and should have done the rings then!

Re: Suggestions for Rings?
I am referring to pistons. The p30's are what were in JDM B16's. They have a larger dome and increase the Compression ratio by a few point. if you were to mill the head .002 and throw a set of p30's in you would be sitting around 10.6 to 10.8:1 compression ratio and i would be willing to put money on you getting another 15 or so HP out of it w/ a tune. Get a set of ITR cams or some smaller tuner cams and you can be looking at 170-180 whp depending on the tune. Those pistons run like 150 bucks w/ machine work and new gasket i would say you get 20 more horses for 300 bucks.

And yes replace the HG EVERY TIME you pull the head off. it is a crush type gasket and is only good for a seal one time around. get some honda bond and seal up the oil ports and you will have a leak-free fresh build.

Re: Suggestions for Rings?
i've used npr rings on 3 different builds, they are good quality and pretty cheap. i filed the gaps on my last build because of a fresh bore and since i'm running higher boost levels.
never used hastings, but they are included with alot of different aftermarket pistons
