Sorry for the English. :D I new here btw
So, i have a 1991 civic ef. It has a swapped d15b (non vtec). I upgraded it to MPFI from DPFI. Car has 150k on the body and 50k on the engine. I'm now rebuilding it. It is gutted because the previous owner wanted to build it as a drag or track car. Then i got it and it has a d15b engine. I drop the d15b engine and look online how many hp and tq it has. Some says it has 75 and some says it has 130 hp . I just want to know how many hp and tq.

Just want to share all of these! :D

I'll post some pictures later on. I bought the car for $250 150k on the body 50k on the engine.

 

There are more than one kind of D15b motors, that varry from 72-130 horse power.

What does the motor stamp say exactly? Most will have a number after the last letter, for example d15b2.

I'm wagering unless it was tinkered with before it's either a d15b1 or d15b2 as you mentioned it was DPFI when you started. But you never know anymore with these old cars people do frankenstien them to hell and back.

 

It says " D15B " thats it.. i don't know why its like that. I found it really weird cause I saw cars with numbers after the B ..

 

Ok, that means the motor was from the japanese market then.

What does the valve cover look like? Where are plugs, the front or the back? Does it have the letters VTEC on the front as well as Honda?

Do you know much about the history of the car or motor?

 

the plugs are located at the back and it doesn't say VTEC

to be honest, i would say about 25/100. I just learned it because I'm fixing my own car. and im only 17.

 

I would wager it's either a japanese D15b1 or 2 due to the way you explain it.

There is nothing wrong with just starting out or learning. Best of luck.

 

So, how many hp do you think?

Lol. Thanks!!

 

I would wager due to how common the motor was vs the std/cx b1. You would have a b2 that would be 92 crank horse power.

 

Thanks

 

 

Hi. I'm searching for the D15b engine wiring diagram, replacing a D16Z6 damaged. the ECU is a P2J-003. All imported directly from Japan. Any data will be appreciated !!!!!

 

Uhmm. I dont know but im sure if you make you own thread they might respond to you. My thread has nothing to do with the d15 diagram. Just sayin. Sorry.

 

I read the D series of Honda on Wiki. They said it came off of CRX not sure what year. (rare engine)
