Engine question

I own an 88 civic Hatchback. It is the STD model apparently. Because it's
not the dx or any other. Now, it's got the D15B2. On the other hand, the DX,
which makes 92 hp aprox, has the same engine. But I have read that there was
a more economic version of this engine, which is the one I have. Is this
true? If it's the same engine, how can it have different horsepower rating?
The manual states the exactly the same bore x stroke specs, as well as the
others, as all the other models (excluting the VTEC). I've found that my
version of this engine has about 70 hp, but I don't know who to believe.
Help would be appreciated, thanks.

 

Be sure to use a condom.

There were at least three different varieties of the 1.5 l engine that
year, the 92 hp (D15B2), a 70 hp (D15B1) and a super fuel efficient 62
hp (D15B6) variety that got 56 mpg in the CRX HF (which is quite a bit
better than what Civic Hybrid gets today). http://tinyurl.com/2drl9
confirms what you believed, but does not add much additional information
beyond that. You can scroll down to the bottom of
http://www.civic4g.com/specslow.htm to find the engine codes.

 

here is another sight with honda engine specs i find a little easier to
navigate http://www.geocities.com/honda_club_egypt/engines.htm , as for
which engine u have, just go by the code on the block, honda usually
has a differant code for every engine even if the block is the same.
the differance in horsepower will be in the head design and fuel
management system, as well the pistons would either be higher or lower
compression, so the engine would have the same displacemnt.

 

Hatch STD ED6 D15B1 ~70hp
DX ED6 D15B2 ~92hp
Si ED7 D16A6 ~108hp


The DX has the D15B2 with 92 hp, not the STD. I have the STD, but with the
D15B2; how can this be?

 

Perhaps it blew a head gasket or broke a timing belt and someone just
replaced the whole engine.

 

Randolf is incorrect- somewhat.
I can't speak for US models, but in Canada in 1988 (excluding the CRX),
Honda released only one model of Civic engine, and it had 92 hp. In fact in
1988, Honda only offered one trim level, and that is the "STD" that Nacho
referred to; auto insurance offices called it 'S.'
In 1989, the Company released an "econo" version of this engine that
generated 70 hp; this latter engine was marketed to compete with the Pontiac
Firefly/ Chevrolet Sprint high-mileage 3 cyl engines. The CRX HF didn't come
out in Canada until after 1989.
Nacho, your car has the 92 hp engine.
