Ok, so im building a boosted ecotec. Ive heard some talk about orings for the block. What are they? Do i need them? What are they for? Why are they used? Any and as much info on this would be greatly appreciated.
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.
Anyone?!?

the prings help with head gasket sealing. yea, you need em...don't know too much about it yet though...thats pretty much it...but mucho importante!

what..?
unless you're building high power (like 500 or more) there's no need for the o-rings.
and you can't just pop them in, you need the block and the head machined to accept them.
but I reiterate, unless you're going for 500hp or more, its unnecessary.

read the .pdf files there about building an ecotec. this information isn't hard to find, it still boggles my mind that people don't know what to do when it comes to these engines. GM made it as simple as they possibly could.
basically it involves machining to the head and block to fit o-rings around each clylinder as part of the head gasket. You will never make enough power that you need to worry about it, spend your money on other things and move on.

^^weird.
hmmm...i could've sworn there was a post about the different head gaskets on here, and a lot of ppl said with the copperhead gaskets, you don't need to o-ring, but everyone said its still very much advised...i'll try to find the thread...

My build goal is 400 to 450 at the wheels. So I'm thinking they might be nessesary. and in terms of not knowing how to build the ecotec, this is the only thing i didnt know about.

Why don't you work on making 450 whp before you worry about this
because if its something i have to do to sustain 450hp i wanna get it done while the engine is in pieces.

anyone looking to build an eco for serious power has three things to worry about.
1) block.
stock sleeves ain't gonna cut it. Look into either having a block fitted with Darton M.I.D. sleeves (modular integrated deck) or the GMR block, which also ties into number 3
2) head.
stock L61 heads are said to blow out without staking. Look it up in the build book. LSJ heads do not have this problem.
3) headgasket seal
if you get the GM racing block its already pre-sleeved and machined for o-rings. you can either get the matching GM head, or have one machined to match the block.
i thought the stock sleeves where good for quite a bit of power. Like i told you the number im aiming for is 400 whp. At that, do you think i need to oring the block?

stock sleeves aren't really good when you start to approach 500. You shouldn't need to o-ring the block so long as you use a cometic headgasket. Some here will say they leak, so if thats the case you can try an LSJ headgasket as an OEM upgrade.
thanx
