Im Building A H22 With A H23 Crank. Im Going To Use Forged Pistons(Don't Know If Its The Best). I Know The Oil Squiters Have To Be Bent, But Should I Just Take Them Out? And Does This Add Power By Taking Them Out? Im Not Sure What To Do. Its Gonna Be All Motor And Bored To 89mm, Ill Use Custom Pistons.

To Be Clear My Questions Are:
1. Do I Take The Oil Squirters Out Of The H22 Or Leave Them In?
2. Does It Add Power To Take The Oil Squirters Out?
3. What Pistons Should I Use Forged Or Aluminum(Spelling?)?

Please Help Thanks Guys.

 

leave them in, just bend them to get em out of the way....your not gonna gain power by taking them out....

 

Should A Machine Shop Do This? What Pistons Do I Use?

 

you should consider removing them due to the fact that even bending them out of the way will not ensure proper clearance esspecially if your going to be boring your cylinders out to an 89mm and since your using the h23 crank you wont be reving high enough to really utilize the squirters anyway without risking a spun bearing or worn cylinder walls..... look into decking the h22 i believe you have to use the f22 crank for this im not sure about the rod and piston combination though as far as pluging it the h23 comes equipped witht he correct size

 

How come I cant rev high with the H23 crank? Im using a H22 Block and head. Everything is going to be fully built, from top to bottom. So I should just take them out? Im really lost now.

 

ok, here is your answer to all your questions. yes have a machine shop take the block and crank and shave the h23 crank shaft to rotate without hitting the oil squiters. modify the pistons as well. that fixes that.

you can rev as high with the h23 crank as you do with the h22 just make sure that you have a cam profile that will work with what you want. if anyone on here tells you different, then either im or email 2point6 on here. he is the one i get all of my info from and look at his motor. 101mm stroke, oil squiters, Vtec, and 90mm bore. answer your question

(not trying to be smart to they guy asking the questions)

 

Sweet thanks.

 

i never had a problem withthe crank hitting i just had the skirts of the pistons hit and i was only using a 87mm bore so thats why i said since your looking to build it any way try decking cause your not gonna have to worry about running a harsh stroke. but thats only my opinion.

 

So are you saying r/s ratio is the same with a H23 or H22 crank????

 

no i dont. the r/s ratio is different. h22 has a longer rod and h23 has a longer stroke.

 

what is the r/s ratio? I use h23 rods and custom pistons right?

 

how has no one mentioned DO NOT USE FORGED PISTONS UNLESS YOU RESLEEVE THE BLOCK, it wont work, dont try it, search around and see the results of peoples pistons and stock frm sleeves

 

Yes that right. ^ And I am sleeveing the block, it's being bored to 89mm.

 

Bump More Help Please

Please Help Thanks Guys. </TD></TR></TABLE>

Forged is the best you can get, and prolly all you can get when buying aftermarket pistons.

And its actually forged aluminum, stock pistons are cast aluminum.

If you're just building a good pro streeter than there are plenty of pistons available that wouldnt have to be custom made, i know Wiseco makes an 89mm that would prolly give you the compression you are looking for. (wiseco.com)

Also make sure the machine shop knows that you are stroking the motor so that the cylinders get bored and honed deep enough.

If it was me id just get rid of the squirters, some people use em and some dont, it really doesnt matter just one more thing you wouldnt have to worry about

 

Sweet Thanks man. So just take out the squirters? Will i ever need them down the road?

Not unless you want to build a tie rack or something

Just remember to put that bolt back in to plug the oil hole.

 

What hole? Its a H22. What do you mean by Tie Rack?

theres a hole from the oil squirters, you wont have oil squirters so block the hole. as far as the tie rack, it was a joke, he meant if youre not using the squirters in your car you could turn it into a tie rack for ties (like around your neck kind of ties).

 

Yes, plug the holes where the squirters where so that you don't loose oil pressure from a now open hole. I've also heard that this will increase pressure to the bearings and actually help.

I've done a bit of research on this setup (H23 rods and crank). I'm still looking/learning though.

I'm thinking H23 crank and rods but I'm not sure on the pistons. I've heard Type S pistons with the H23 stuff will give like 12.3:1 compression? Is that about right?

Would/should I want to resleeve if I use the Type S pistons though? They are not forged, are they? If I go forged aftermarket, I'll resleeve for sure!

 

ok, type S pistons as long as they are from honda, they are OEM aka no sleeving necessary. the forged piston without sleeving is bull, look under the FAQ thread at the top. next, the hole in the back of the block needs to be open. oil squirters need to be there and will be installed from earlier in the post. so dont plug anything. the piston bit. only modify whatever piston you will get. the piston skirt hits the oil squirters because of the stroke so keep that in mind. otherwise have fun.

 

true to all most everything depending on the rpm range that your going to be operating in the oil squirters are not nessecery since he is essentially using an h23 bottom end wich is i dentical to the h22 except or minor things like the oil pump and a smaller orfice(plug) between the head and the block for the oil feed. so if you choose not to use them be cause your red line is like 7500 rpms and this a street car so you dont have to worry about high revs then just plug it cause a stock h23 comes with the plug and all thats doing is preventing th pil from traveling through the lines where the squirters should be. but enevitably its up to you cause only you know what your building your motor for.......in my opinion though ifyou got the squirters use em i just got rid of mine cause due to clearance problems one of the lines was sheared off so thats the end of my attempt..

 

bUMP

 

Im gonna use the squiters. But i still think forged pistons will be the best with the block sleeved. You guys all agree?

 

i would leave them in. alittle extra lubrication never hurt anything.
if you are using forged rods then you can spin that engine till it stops making power
