Just spun a brearing on my JDM H23 DOHC VTEC [blue top]
Just spun a brearing on my JDM H23 DOHC VTEC [blue top]
I need to know the part numbers for the main bearings and the connecting rod bearings.
As far as I can tell the main bearings are the same between the H23 and the H22's
But the connecting rod bearings are different due to the different stroke and size of the crank.
Now the main bearings are no problem, but the connecting rod bearings are confusing me. I think my engine is basically a h22 head on a h23 block, kind of like an original frankenstein from Honda.
Part numbers is what i need, .25 over standard.

No, it is a H22 type S. They use H22 bearings. I would suggest you to replace all of the bearing at the same time. Save you a lot of headaches and money later.

Re: Just spun a brearing on my JDM H22 DOHC VTEC [blue top] (Turbo9Nut)
its going to need machined, take it all apart and spec the entire motor... remember this is metal all through it now as well.
...call honda, tell them 99 prelude. there are all kind of bearings as well...u need to spec it, probably AFTER it needs machined.

sounds like what you have is actually an H23A blue top JDM twin cam. and no one knows what parts they require (at least i have found that). your best and safest bet is to dismantle it, take the actual bearings with you and find replacements.

JDM H22A DOHC VTEC engines do not come stock with a blue valve cover...
https://honda-tech.com/zerothread?id=641555
...although they can be purchased seperately and will fit perfectly onto any H22A. If the code on your block says H22A, then you don't have to worry about finding "rare" parts.
Let us know what the block says...H22A or H23A!

Re: Just spun a brearing on my JDM H22 DOHC VTEC [blue top] (99blackvti)
Sorry for the typo, i meant its an h23a
The block has h23a written on it. Also, i cant really compare the parts here, I have to order stuff from america to do so, because nothing is available here.
I checked on hondaautomotiveparts.com and I found that the 91-99 preludes have the SAME main bearings but the rod bearings differ.
I have an 87 bore along with a 95 stroke if that helps at all.
Also need a headgasket..which one do I need? h23 prelude or an h22 one?
thanks.

I'm almost positive that you can't order JDM H23A specific parts from the US...

I know! Not even satan_srv knows, and he knows more about the different H/F series engines than almost anybody I know...bummer! I hope I never break anything unique to the H23A

ha ha ha. you got that right!!
although i still want to know: how did he spin a bearing on a 55mm main??

Well first of all just cause it has 55mm mains doesn't mean the motor wasn't be abused and not maintain... there are many factors... And second, has anyone ever cracked open one of these blocks and measured to see if the mains are 55mm? If they are 55mm you would need 98+ H/F bearings and if they are smaller you would need 97 and below... But like someone already stated, if you spun a bearing the crank will probably have to be turned...

Re: (Sam1am26)
This is bad....
Anyways, like I said before, the mains are most likely the same as an h22...but thats all I know at the moment.

Re: Just spun a brearing on my JDM H23 DOHC VTEC [blue top] (99blackvti)
Well, I have been looking around on some of these spec sheets and have seen different sizes for the rod and main bearings.
I recently got Type S pistons, .25 over and don't foresee any problems fitting these pistons in because i believe the standard bore is 87mm.
It seems the measurement for all the main bearings for all the h22's and h23's is .784. I also checked some online parts stores and the part number for the main bearings are all the same for 92-99 preludes.
.762 is the measurement for all the h22 and h23s as well. Is this anything? does this vary from the main and rod journals? these vary 50mm to 55mm and the journals on the rods go from 1.888 to 1.771
Now my crank is going to have to be reground, and the mechanic here in Pakistan says I need .25 over standard. Now is the bearing thickness really going to matter is my crank will be ground accordingly to these bearings??
Please..someone help me...

waht ur gonna need todo is have the crank journal reground then measure the diameter of the journal and the inside diameter of the rod, then calculate what bearing size you need to use to acheive the proper clearance

and those type-s pistons are going to "stick out of the hole" quite a bit.
unless you've actually compared them to the JDM H23A ones. did you take pics of a side by side?

Re: (iakona)
problem is i couldnt. Im in pakistan here and nothing is available here. the original 10.6 pistons seemed like they had a considerable hump in them. hope everything works out.
Besides that, i still need to know which bearings to order? what model prelude ones do i need? those for the 93 h23 or the 97+ h22

you should be able to use stock h22a4 98+ bearings.. the h23a is 55mm main. and the rod bearings should be the same as any usdm h22/h23
the problem is that if you spun a bearing is likely hood that the crank will need to be turned and you will end up getting a custom oversized bearing anyway.

your telling me after you put the type s pistons that should have a taller compression hegiht on the h23a rods and had the crank back in the block all tourqued down the piston doesn't come up to the deck height?
if anything the type s piston should end up sticking out more than the h23a piston
ususally the way it works is anything h23 whether it be the h23a or the h23a1 with the smaller 50mm mains they all have a shotter compresion height (ie measure from the middle of the pin to top of piston) . while the h22 has a taller compression height.

The info I have found is that these engines have the same issue with availability of bearings. While JDM engines are quite cool, the availability of normal service parts is quite a pain in the a**. I am working on the problem and will post again when I have the resolution.
