I've read that the 90/91 only had ~130 hp whereas the 92/93 b18a had closer to 140 hp.

Can anyone verify this?

Is there any difference at all in the b18a's....if so, what is it?

Shopping for one soon!

 

i heard that the 92-93 intake manifold was bigger or sumtin like that, but it is also obd1 but the 90-91 is obd0 so iono if that makes a difference

 

The b18a and b18b are the same strength wise. A B18B makes an extra 10-12 hp due to slightly better cams and intake manifold, thats it.

The B18B also has a better head casting with larger intake ports and better ECU programming (compared to the 1990-1991 PR4).

 

Guys I'm not asking about the b18b. I'm asking about the b18a.

I know the b18b is stronger, and by stronger I mean has more power.

Let me rephrase...I heard the 92/93 b18a is more powerful than the 90/91. Is this true?

And is the 92/93 really OBDI? I thought that didn't happen until '94 with the b18b?

More powerfull? What the heck do you mean....its basically the same engine, what do mean more powerful?

OBD1 started in 1992, "not" 94.

 

i think he's meaning, does it have better fuel maps in obd1, does it have slightly different cams (kinda like the 89-91 d16a6 had a different cam than the 88) etc.

 

You can build a B18A1 just as good as a B18B ive got a build with a B18A with usdm type-r pistons and im porting the head now and it will make just as good power as if you did it with a b18b

True, but the differemce in price btween the 2 engines is only like $100 used. What you just quoted cost a hell of a lot more to do.

I think for the money a B20 is the best deal. Its also like a B18a/b, but it is newer, has the same dimensions as the b18, uses the same rods, crank and head, and makes extra torque do to it 84mm bore that has a greater displament at 2.0L

 

Guys, you are still not understanding what I'm saying.

I, at one point, read that the 90/91 B18A engine was rated at 130 hp. And that in '92, the power rating increased to around 140hp.

Is this true? Can anyone confirm or deny this?That's all I'm wondering.

I can pick up complete b18a swaps from my local junkyard for $175. They don't have any b18b's....so I'm looking to get the most powerful b18a that Honda produced.

Can nobody verify if the b18a had different power ratings between the years 90/91 and 92/93? That's all I'm wondering.

If nobody can confirm/deny what I'm asking, I'll just look for a 92+ b18a.

Thanks guys.

 

Deetz, you answered my question exactly in another thread. Why are you acting like i'm an idiot for asking it? lol

Here is exactly what non vtec b18's come as:
90-91 B18A 130hp, obd0
92-93 B18A 140hp, obd1 -better int manifold and cams
94+ B18B 142hp- (obd1 in 94-95, and obdII in 96+), slight tweek in ecu"

 

You are correct, looking at Edmunds you find that the 1991 Acura Integra LS had 130 hp / 121 ft-lbs while the 1992 Acura Integra LS had 140 hp / 126 ft-lbs.

 

yes it is true

 

yeah its is true

Sorry...i was getting the impression you were trying to differentiate the actaully strenght from one block to another, meaning one could handle more than he other.

Oh, I see. I guess I wasn't clear enough.

Thanks for the informative post in the other thread!

Thanks for the info guys.
