Where's the engine code

[thegreatdane]

I cant find the engine code on the engine in my new accord.. :rolleyes:
It has 2 Keihin carburetors and the tranny code says: GM-3645516
Does anyone know where to look or can say from the tranny number what engine it is? From the valve cover it looks like a Prelude engine.

that sounds just like the dual carb prelude engine. dont know which one it is. if you know where the engine code is on your other hondas, it should be in the same place. right on the block on a little ledge thing. if your looking at the engine with your hood up, its on the left side in the front. mine was covered with gunk, but it was there after i cleaned it off. dont know if that helps. is it single or dual cam? i know they made A series engines with single cam dual carb and dual cam dual carb. it could be any of the A16, A18, or A20. i think A16 was an engine, havent seen many, only on the honda web site. those may have only been in some civics. i'll look up some engines and see what was in the accord with dual carb.
...........ok, what trim level do you have? Ex. LX,DX, EX-S, EX-LS. is it a sedan, coupe, or aerodeck? what year? if you can give me that, then i can likely have an idea on what engine you have.

[thegreatdane]

It doesnt have the ledge like the A20 and B20's.
It's an '87 sedan Ex trim level. The plate on the firewall says A20A2, so there must have been swapped in another engine, since to my knowledge A20A2's never had two keihin carburetors but one single.

[HondaBoy]

well, you know that may actually be the right engine. as for US models, ours were A20A1 and A20A3, so mabey A20A2 is correct. let me see if i can find anything about that one. you may have the EX-S model, the "S" isnt present i dont think.......hey is it single or dual cam? that would be the thing to know.

[thegreatdane]

Single cam, 12 valve. I have another carbureted Accord engine lying around, and it's engine code is A20A and it has the normal carburetor. But A20A2 is the same engine though. I dont think this engine can be an A20A2 because of the missing ledge with the engine code and the dual keihin.
Is it possible to dig up anything from the tranny number?

What or where is the engine code? Were these engines only Prelude engines or also Accord engines?

[HondaBoy]

that looks like the engine in the 2nd gen accord. is your's a 3rd gen? if so i'll keep looking up stuff.

[thegreatdane]

It's a 3rd gen yes. But I think it's just a 2nd gen Prelude engine that's been dropped in.

[shepherd79]

how can it be the 3rd gen when the hood opens diff direction, away from the driver.
it looks like A18A motor to me. they were standart on 2G prelude. they weren't available on 3G accord.
all honda engines have the engine model at the same spot. just keep looking, it may be under layer of dirt and oil.

[Morpheus]

there was no dual cam A20

I think that engine was available both in 1.8 and 2.0 litres in the Prelude. I dont think they were in the Accord though as you say too.
And this engine does not have the little ledge with the engine number at the same place as other Honda engines.

[shepherd79]

the motor is A18A.
i have never seen the A20A motor with dual keihin carbs like the one you have.
plus you can't just swap that intake minifold with carbs from A18A to A20A. the bolt pattern on the heads are diff. the only way to have A20A with this kind of carbs if you swap A18A head onto A20A block. thus raising compression and giving you two sidedrafter carbs.

[thegreatdane]

This german page claims that there is both a 1.8 and 2.0 litre dual carburetor engine.
http://www.prelude-fan.de/ab_t.htm
The page seems to be based on data from european Ludes only so perhaps this engine was available in europe and not in the US.
But the A18A head should fit a A20A directly?

[shepherd79]

i guess you are right. it may be A20 with dual keihin carbs. WOW. that is something i didn't know.
yeah, A18 head will fit A20 block with no problem.

[wprocomp]

got a complete pic of that car?

[wprocomp]

how can it be a 3rd gen when the hood latch is on the wrong side?

[thegreatdane]

That picture is of a 2nd gen prelude.

shepherd79-> The webpage might be mistaken though. Who knows :)
