Hello,

I'm a newbie here. I've just got an Wagovan 86 with the engine #:

EW-1630395

How do i tell if it's an EW1, EW2 or EW3 engine ?

Thank you very much !

Look just to the left of the exhaust mainfold, where the block mates to the transmission. There is a flat square area with numbers stamped into it. Your engine code should be there.

D16xx
Or D15xx

@2000redCIVICsi, the engine code EW-1630395 i read from the place you tell me. However, i have no glue wether this engine code translates to a EW1, EW2 or EW3 ??? OR D15A1, D15A2 OR D15A3 ?

This is what you're looking for. Obviously yours won't be a B16A, but thats just an example of what it should look like




yes I know the two pics are of different engines

Honda E engine - Wikipedia, the free encyclopedia

Looks like you have an EW1 (D15)

EW

The final E-family engine was the EW, presented along with the all new third generation Honda Civic in September 1983. Displacing 1,488 cc (1.5 L; 90.8 cu in), the EWs were SOHC 12-valve engines. Early 3 barrel EW1s produced from 58 to 76 hp (43 to 57 kW) and 108 to 114 N·m (79.7 to 84.1 lb·ft). The fuel injected EW3 and EW4 produced 91 hp (68 kW) at 5,500 rpm and 126 N·m (92.9 lb·ft) at 4,500 rpm. The "EW" name was replaced by the Honda D15 series, with the EW (1, 2, 3, 4, and 5) renamed to D15A (1, 2, 3, 4, and 5) in 1987. It also received a new engine stamp placement on the front of the engine like the "modern D series" (1988+).

-EW1
1983-1985 Honda Civic/CRX DX (unlabeled)
1983-1986 Honda Civic
1983-1986 Honda Shuttle

-EW2
1983-1987 Honda Civic non-CVCC EFI (CDM)

-EW3
1985- Honda Civic/CRX Si non-CVCC

-EW4
1985-1986 Honda CRX Si non-CVCC
1986 Honda Civic Si non-CVCC

-EW5
similar to the EW1, Fuel injected CVCC 12Valve 4 Aux valves. A third throttle plate in the throttle body supplied intake air to a 5th injector which powered the CVCC ports, The rated power is different between the Civic and the CR-X: the Civic makes 100 PS (74 kW) at 5,800 rpm and 13.2 kg·m (95.5 lb·ft) torque at 4,000 rpm, the CR-X made 110 PS (108 hp) at 5,800 rpm and 13.8 kg·m (99.8 lb·ft) torque at 4,500 rpm. Differences in power are largely down to a more efficient exhaust system on the CR-X it used a factory cast iron 4-2-1 extractor went through a catalytic converter further down the exhaust system and had twin exit tail pipes. The Civic had a short 4-1 design into a catalytic converter and single pipe exit. There was a revised intake manifold for vehicles produced in 1986 and 1987. The EW5 was only available in Japan. It came in the following models: CR-X 1.5i, Civic 25i Hatchback, Ballade CRi Sedan.

Thank you very much !

I read this before posting the question and also though that it's an EW1. However, i'm posting to seek other ways to verify this. I hope i can know more about the engine through the engine code.

I also read the D15 series wiki and found that "EW-1" is the head-code for D15A1 engine.

Looks like you have an EW1 (D15)

The engine code i posted were from the other side of the block (intake side). I didn't know that there is one on the exhaust side like you and 2000redCIVIC advises.

I will check this out and report back soon. Thank you !

It says the EW1 was later rebadged to D15. Its very likely the heads never got restamped. You have what is essentially a D15. Most parts SHOULD be interchangable, but dont take my word for it.

The D15Ax engines are not compatible with any 88+ USDM engine.

At all.
I confirm that! There are some parts that are compatible with the 86-69 Integra motors but that is about it.

The Wagovan block will bolt up to the Integra transmission, but all of the other EW series blocks will not.

With a little work you can put the Integra head on the EW block.

You can swap the 86-76 Integra drivetrain into a 84-87 Civic/CRX chassis if they wre the Si model (or you have to swap in the full wiring harness and ECU if you have a DX or non-badged model).

Yeah thats why I said not to quote me. I only knew what I read when researching. Glad we have some that have knowlege about these motors.

I checked it and there is no engine number on the exhaust side of the block for the EW.

The engine code i posted were from the other side of the block (intake side). I didn't know that there is one on the exhaust side like you and 2000redCIVIC advises.

I will check this out and report back soon. Thank you !

There is another little problem with my wagovan :saddam:

The block was replaced before (sometime in 200X) so i don't know what block version is it but i know it's an EW block :thinking:

I know this because my wagovan is a Canadian model and there is a badge on the chasis which tell us the original #. And the engine number on the badge on the chasis is different from the engine number on the block. Here is the details:

Engine number on the block:
EW-1630395

Engine number on the chasis (original engine)
EW1-3556838

Engine number on the chasis says it very clear that it's an EW1. However, engine # on the block (the current engine) doesn't.

I read all the service manuals for 85, 86, 87 Civic but i'm still not able to decode this engine. The manual says the first 2 digits after the "-" are the model year and engine codes. But it doesn't have details about the number "16" in my block.

I confirm that! There are some parts that are compatible with the 86-69 Integra motors but that is about it.

The Wagovan block will bolt up to the Integra transmission, but all of the other EW series blocks will not.

With a little work you can put the Integra head on the EW block.

You can swap the 86-76 Integra drivetrain into a 84-87 Civic/CRX chassis if they wre the Si model (or you have to swap in the full wiring harness and ECU if you have a DX or non-badged model).

There is only one block style (bolt pattern on the end for the transmission) for those cars, so regardless of if it is EW1, EW2 ect the internals for all of the 1.5L motor will work in that block.

What is it you are trying to do?

Hello gtpilot,

I'm doing a study of what are the possibilities of swapping the head (some EFI model). I've been reading on Wiki that EW1 & EW2 are different in horse powers & fuel consumptions significantly. The number bellow in GREEN impressed me :taz:

D15A1

Found In:
1984–1987 Honda CRX

Valvetrain : SOHC (3 valves per cylinder), non VTEC
Fuel Control : OBD-0 12/v PGM-CARB
Redline : 6,500 rpm
Economy : 31/38 mpg
Head code : EW-1
ECU : –
Transmission : DA48
Gear ratios : 2.38/ 1.76/ 1.18/ 0.85/ 0.71
Final drive ratio : 4.27

D15A2

Found in :
1984–1987 Honda CRX HF Grifin
Displacement : 1,488 cc
Compression : 10.0:1
Power : 60 hp (45 kW) at 5,550 rpm
Torque : 73 lb·ft at 3,500 rpm
Redline : 6,000 rpm
Valvetrain : OBD-0 8/v EFI (HF Model)

Gear ratios : 2.92/?/?/?/0.65

1987 Honda Civic Wagon RT4WD (Canadian Model)

Power : 76 hp at 5,500 rpm
Torque : 84 lb·ft at 3,500 rpm
Valvetrain : 12 valves, SOHC
Economy : 31-38 mpg


I'm glad that there are experienced people hear so that i can ask for advises. What are the posibilities ? My objectives are:

  • Multi-point EFI (i need all the wiring hardness because it's currently a carb)
  • Good MPG, i don't need much power, just want to swap from carb to EFI for MPG
There is only one block style (bolt pattern on the end for the transmission) for those cars, so regardless of if it is EW1, EW2 ect the internals for all of the 1.5L motor will work in that block.
