Will ES2 Intake Manifold bolt on ET2 Head ?

[oneslammedlxi]

will an ES2 intake manifold bolt directly onto my ET2?

(ES2 is from a 2nd gen carbed accord)


i was thinking it should, because most parts are intechangable within honda engine series'

like a b16 manifold will fit a b18
or a d16z6 intake will fit a d16y8


anyone know....?

thanks!

[smufguy]

what is the engine code on the motor? A18. i think its the same or has to be the same bolt pattern. Cause from what i can recall its nothing but they just bored it to get our A20.

A18A = 1829cc = 80,0 x 91,0 (Bore X Stroke) 2nd gen accord motor
A20A = 1955cc = 82,7 x 91,0 (Bore X Stroke) 3rd gen motor.

[oneslammedlxi]

the engine codes are stated above, my lude is an ET2 and the 'cord is a ES2

weird, i cant seem to find an engine like that. Possibly a different coded A18 engine. Are u from canada or something? Cause they got weird shit as BT and what not for the A20s.

OH wait, if ur talking about the cars on the sig, then yeah THe 2nd gen lude and the 3rd gen accord used the same motors so parts are interchangeable, even tho part number might be different, like the distributor and stuff.

[k-roy]

Those are real engine codes, just older than 86. They are 12 valve heads, so there is a possibility.

The only real way to tell is to try to see if they bolt up. Or you could go to a parts store and compare intake gaskets. You got about a 50/50 shot of it working out. Good luck!

actually the intake manifold from a 3g lx accord will not bolt onto a carbed 2nd gen lude...

please do not post information unless you know it to be 100% correct

[oneslammedlxi]

i will be finding out today, i will keep you all posted on my progress

[2ndgenludedude1986]

let me settle this. es- in older lude form 83-84 and in all 2nd gne accords.
et2 -in 85-86 ludes
a18- ONLY IN 87 Carbed LUDES
a20a1- 86-89 3rd gen accord carbed motor
A20A3- 86-87 SI LUDES, 86-89 accords
BT- 86 ludes in some casses. i dont see to many of these. same as a a20a3
the a18 WAS NOT in the 2nd gen accord.

only a20 parsta are intercahngeable. the heads are intercahngeable betwwen teh a20 and a18 and et2. the intake manifodlas are intercahngeable prolly on teh es to the et2 to the a18.

umm dude. I dont know where u live, but the 2nd gen lude and the 3rd gen accord hvae the same engines. Or atleast the ones i have seen and the ones ppl have. we have ppl with distrubutors from the 2nd gen lude on the 3g and this is for the efi, :ugh: .

Also i have seen ppl put A18 crank on a A20, i dont know why that was left out in the parts interchangability. and A18 did come in an accord from the years 85-89, in Japan. u can look it up if u want.

from what i can see that the ES came in accord from 83-85 and the prelude 83-87

Et was the same 83 - 85 accords and 82-87 ludes.

Both engines were the exact same disp 1830 cc (1.8L) and were same bore and stroke.
Just trying to help you man. :uh:

[2ndgenludedude1986]

in the 2nd gne lude, the es was only in the 83 and 84. some of the 84 had et enignes in them. the efi a20 in the 86 and 87 lude are the onely intecangeable engine parts on the 3rd gen accord. yes the a18 crank will work . the a18 and a20 block are identical except the a20 ahs a larger displacement. thats why a18 heads can swap over on a20 blocks. the a18 coudl very possible be in teh late 85 accords which woudl be the 3rd gens. but only in japan. from what i understand there wasnt a a20a1 in japan. only in other countries.

[smufguy]

my recollection was that the A20 was a stroked out A18 block. But from the specs it looks like A20 was a bored out A18 block. Which makes the head swap difficult due to different bore size. on the other hand, A16 and A18 are the same bore with longer stroke on the A18 making the headswap easy? But again, am i looking at something different, or im just dumb? :( im not a morning person and its 840 am :(.

Oh from what i can see, there were A20 accord and lude in japan. The accord with that motor was in US, Canada and Japan.

[2ndgenludedude1986]

i have a18/et2 (identical) head on a a20a3 right now. i jsut neede to get he combustion chambers bored out on the a18 becasue of the lasrger bore of the a20. everythign lines up perfect. all teh a20 is a a bored out a18/et2 blco. (again a18 and et2 idential in everyway)


waht is the a16? never saw it anywhere in my life! hhaha :dunno:

[oneslammedlxi]

i have an et2

not much will work on an a18

yes, the a20 parts will work on a 3g, but thats not what im dealing with in this case

sorry, i didnt mean to be an ass, i know your trying to help :D

[smufguy]

from what i can see and the point of our convo here is just that the ES and the ET blocks are pretty much the same like the A20 and the BT. From what the pics i can see, they look exactly the same. I dont know why they were named like ES and ET even tho they both came either with a 1 Kehien acc or 2 Kehien lude carbs.

[oneslammedlxi]

nope, tried it wont fit...damnit...will an et2 dizzy work on an a20?
im thinking of just dropping my a20 in there and carbing it

[phrenology]

will an ES2 intake manifold bolt directly onto my ET2?

thanks!

What are you trying to do with an ES2 manilfold? Is your ET2 CVCC?
If you want I have a nice custom mod for you. Before I ditched my ES2 setup completely I had an adapter plate put on my intake manifold to use an aftermarket Holley downdraft carb, which ran alot better than the stock 3bbl Honda carb. If you are interested look at my cardomain page. Make me a reasonable offer and you can have the custom modified intake manifold with adapter plate. I would request that you pay shipping too.

[A20A1]

I thought the A18 head swapped onto the A20 inscrease compression because of the smaller size... if you bore out the head to match the A20 cylinders wont that drop the compression, you might as well stick with the A20 head... or are the valve sizes the same between A18 A20, I doubt it but anyways...

Why use the A20 manifold... if you find the A20 manifold fits then go one step further and take advantage of the aftermarket B16/B18 manifolds. Anyways I'm going off on a tagnet... :blah:

[smufguy]

well mike, even so, who knows if the clearance volume is smaller than the A20s. Besides, being the bores are different, i dont know how they will bore out the A18 head even if they can, thats nothing i have heard of before and wonder what it will do to the coolant ports and stuff.

[Sabz5150]

let me settle this. es- in older lude form 83-84 and in all 2nd gne accords.
et2 -in 85-86 ludes
a18- ONLY IN 87 Carbed LUDES
a20a1- 86-89 3rd gen accord carbed motor
A20A3- 86-87 SI LUDES, 86-89 accords
BT- 86 ludes in some casses. i dont see to many of these. same as a a20a3
the a18 WAS NOT in the 2nd gen accord.

only a20 parsta are intercahngeable. the heads are intercahngeable betwwen teh a20 and a18 and et2. the intake manifodlas are intercahngeable prolly on teh es to the et2 to the a18.

The BT series engine was in the 86 Accords. I've got one. There is no difference between it and an 87 A20A3

[PhydeauX]

... trying to make sense of every direction this thread is going....

No the ES2 manifold doesn't work on an ET2 head. ES2 is a cvcc motor, completely diferent flange.

Yes, the ET2 distributor will work on a carbed a20, I'm using one right now. It also has a slightly more agressive timing curve then the carbed a20 distributor.

No the a20 manifold doesn't fit the ET head. ET's have round ports, A20s are oval.

When you bore the head all you really do is enlarge the bottom of the combustion chamber slightly so its edge does not hang into the cylender. It's not a clearance thing, edges tend to cause hot spots, and hot spots cause detonation.

Then you have changed the CC of the combustion (made it larger) chamber thus negating any effect on compression you are seeking. or are you just trying to be differant?


Heres a calculator to let you figure the compression yourself plus it explains about compresion a little too.

Hers another on how to check the CC of your combustion chambers and cylinder if you want to . Moparts is my favorite site BTW.
