ok whats up guys, i just wanted to throw this out here since i havent seen this or heard about this kind of build before... i kno im probably not the first but just wanted to see what you guys thought

i have a complete h22a and a complete h23a1
i recently got ARIAS 11:1 forged pistons, the thing is you cant just put those pistons into the h22a becasue of the special FRM cylinder liner. i would have to sleeve the motor for those pistons to work. but the h23a1 doesnt have the FRM liner, so this is what i got and what im going to do

im gonna dissasemble my h23 block and hot tank it, take the crank out of the h22a and micro polish and balance it, put my ARIAS 11:1 pistons, eagle H-beam forged rods, ACL bearing kit in.

crower stage 2 cams and cam gears, crower valvetrain, the h22a head is at the machine shop right now getting hot tanked, a 3-angle valve job, valve seals, titanium vlaves( most of the stock valves were bent ), valve guides and the head milled .0025 to bump the compression to 11.5 and a port and polish. the head is going to go on the built block with the eagle vtec conversion kit. skunk2 IM and skunk2 68 mm TB and hondata intake manifold gasket and camp 1320 header

so all together i have the built block with the built head, ACT 6-PUCK unsprung clutch and the h23a tranny with quafe lsd.. i figured i should use the h23a tranny because ill never catch traction with the closer gear h22a tranny lol

finally im going to get it tuned by JOHN KERR, a local guy thats amazing with tuning
its going to get tuned for all motor right now then when i can afoord a direct port nitrous kit im going to tune it for either a 100 shot or 150 shot

and the best thing out of all of this is im gona be using the h23a1 motor casing so although its basically gonna be an h22, the engine stamp is gonna say h23, i also shaved the DOHC VTEC symbol off the vavle cover, so to the idiots on the street wil go " its just a low compression h23"

i know im leaving alot of stuff out but please give me so feedback or any advice.. thanks guys

FRM liner? First im hearing about this. But your not the first to do a build like this. Its as common as mini - me swaps.

x2 but i dont mess with h swaps very often..

but def sound slike its gonna be a good motor.

good luck with the build. pics are allways a plus..

 

eagle makes a h23 vtec conversion kit?.

make sure to take the oil control plug off the deck of the blok. Looking down at the pistons, its on the top, should be a allenstyle plug

its deff not as common as a mini-me swap so go kill yourself, im using the h23 block but h22 interanls. im not just slapping the h22 head on my h23.
yes, the h22a has a special FRM (fiber re-inforced metal) liner.. it is kind of like ghetto sleeves but they really do help. the only type of forged pistons that will work without sleeving the motor are mahle golds. any other forged pistons will eat up the block and pistons. but the thing is i got the forged arias pistons and eagle rods from an old guy for $40 which is amazing

no they dont makes a conversion kit, but the h23 and the h22 are the same block,just the h23 has different stroke, compression, etc, etc, etc. everything from the h22 can be swapped into the h23.. im just gonna use the h22 crank and put that in the h23 with my pistons and rods. the crank goes right in. i did my research, ive called ARIAS, MAHLE, CP, and a couple local proffesional tuners and shops. they all confirmed it was possible. ARIAS actually has done this setup and is still running today

 

yes i know they fit.. ive built more than a handfull of h23/vtec motors . Im just saying dont forget the oil control plug on the block... And dont forget to use h22 head studs.

 

sorry to burst your bubble but you have a lot of reading to do my friend.

H23s have the same FRM liner as the h22 block. only a few of the F series blocks have the steel sleeves.

You can not run those forged pistons in the h23 block for the same reason as you cant in the h22 block.

I would use the h23 crank in the block to make it a real 2.3l.

There is an h23vtec ( h23 block , h22 head) link in the FAQ thread of the Prelude forum. I suggest you read it !

good luck

 

im pretty sure the h23 is not frm

sorry to burst "your" bubble but i have done my reading and studying. i have called 5 different companys including CP & ARIAS who both have done these builds and they have all said that the h23 does not have the FRM liner

let me also add that i am a honda technician and i have contact with the manufacturers... o ****, they also said there is no frm liner, but hey what do they kno, they just build the things

Guess you should go get re certified mr honda technician.

I was trying to help you out and you want to be a smart ***. Good call buddy. read this thread please.

And while your at it, why dont you tell us all what dealership you work at so we can remember to never go there.

Again,

Good luck

 

haha ok so you can read something that someone else has wrote. let me note again that i have talked to people that actually work where these are made and know every spec to a tee and i also have talked to people that have done this build before, im not being a smart *** , im just stating the fact. so idk bout you but i think id take the word from someone that actually knows for a fact what there talking about and have build this before rather than someone that thinks there " master technician " becasue they have a honda-tech account. and yes im a certified honda technicain.. i say that so people dont think im some smart *** that " thinks" i kno what im talking about... so please go off and find some other thread that someone else wrote to try to prove me wrong again

 

what i have is a usdm h23 which does not have the frm liner.... yes the jdm h23 has the frm line but i have the h23a1 " USDM "

 

I have a h23a1 block at my shop and know for a fact that they have the same FRM walls as the h22. I tore my H22 down and had it sleeved and know what that **** looks like.

it looks almost like FRM liner but i promise you that its not FRM. , im not trying to be a dick or anything but i called and spoke to people that have done this hands on and have built these motors and have done plenty of the setups im doing. this is not implied to you "boots89" but i just hate people that try to start ****. like i tried selling my last h22a longblock which was mint, absolutely nothing rong with it for 800 and i had people ive never met or talked to before say that they have seen the motor in person and its junk... im like wtf?, do people just get a honda-tech accounts just for that ****

 

yea Im not trying to start **** I just don't want you to ruin your engine.

 

Just out of curiosity I called Arias pistons and spoke with Tom Jung who is there sport compact consultant. I called him as if this were my setup and he recommended I swap everything over to the H23. Use the H22 crank, eagle rods and arias pistons into the H23 block. No re sleeving required.
Called the number from the Arias website and they connected me with him.
Apparently he's been doing this for awhile and has alot of experience.

 

I HAVE built this engine and will give you some advise.

Use the h22 block and have a machine shop put some basic cast iron sleeves in it. Should only be a couple hundred bucks to install. The h22 block has oil squirters that you should use. You may have to bend them slightly to fit around the H23 crank. Which brings me to my next point. In order to make it a true h23/vtec you must use the h23 crank and rods. If your basing your compression off of h23 specs it will actually go up based on the h22's smaller combustion chamber so no need to mill the head. This is all based on both blocks being of the 92-96 variety. If you can scrap the h series tranny all together that would be preferable and go h2b. IF you're gonna do it, do it right and follow these basic guidelines. You will be happy. Also ditch the crower 2's and get some blox 2's and don't skimp on the header. a dc will NOT help.

 

I was not doubting the fact that arias can make a piston to work with the frm. Mahle gold series pistons are not made of some magic material, they just have a coating on them that allows them to be used with the FRM, i will guess that arias can make a piston the same way. Never once did i say that part was not true.

H23 blocks, usdm or jdm are made from frm. its a fact.

I really could give a **** less if you believe it or not.

I started to post because I didnt want someone using mis-information to hurt their motor. Obviously in your infinite wisdom you are much smarter than the masses.

Good luck

 

Get a damn helms manual and check man, you wanna borrow mine? FRM!!!!!!!!
