I recently discouvered that my 93 DX isn't a DX, it has a JDM D15B under the hood. I know it is JDM by the japanese writing all over it and the absence of english. I have two questions though, how to i figure out how old the engine is and which varient of the D15B it is. I've done a lot of searching and the D15B can have anywhere from 90 some odd HP to the 130HP varient (which i hope mine is) My car definately feels like its got a lot more power then 90HP. Oh and most importantly which computer is my engine suppose to have b/c im sure it has the wrong computer thx jason

 

p08 ecu

 

thx bro, any idea on how to fingure out which version of the d15b i have?

 

check the stamp, dyno

 

which stamp the one right by the marking that has the engine type (D15B?)

 

your valve cover does say vtec on it correct?

 

There are a few types of the D15b my valve cover isn't this one http://asia.vtec.net/article/d15b/d15b.jpg its the black valve cover but most of the paint on it has flaked off and im' not sure if it says vtec

 

i believe it says vtec

 

so u cant tell if your motor has vtec? ud think you could when you hit 5500 rpm.

 

yeah u'd think, the last vtec i drove was a type r, and when the vtec kicked in it was brutally obvious, on my d15b it isn't as obvious

 

If it said vtec you could tell even if the paint was gone. The words actually stick out, they aren't just painted on.

 

yeah i know, i'd go check but its at the body shop gettin sum work done. dammit. if indeed it says vtec can i be certain it has 130HP?

 

It should look like this:

i swear it looks identical to that one, i just can't remember off the top of my head if it says vtec or just honda? is there another varient with a black valve cover that just says honda? thx guys

 

If the spark plugs are in the front, closer to the header, it usually means vtec. Where or who did you buy the car from? Did it have any mods when you got it?

 

is there a vtec soleiod on the back of the valve cover?????/

 

dammit i wish i could go out and check i have no clue right now... but is the vtec varient the only one with 130hp

 

If the car had some mods when you bought it, the previous owner might have done a mini-me, which would basically be the same as the 130 hp d15b.

 

ehh well the d16z6 has 128

yeah the only d15b JDM with vtec has 130
whats redline?

 

its a dx, there is no tac on the gauge cluster so i don't know the red line and the engine is stamped (from the factory) D15B . i got the car for a steal (paid 2000) its almost in mint condition. didn't even check under the hood until recent

 

Are you sure it's not this:

 

it looks more like your pic b/c i know the spark plug wires run to the back of the engine and are not at the front like the first pic posted. but its a 93 (the car) and the engine is stamped D15B, well the bottom end is

 

i wish i had AC like yours lol dammit it gets hot sum times

 

Ok, then this is probably going to be some sad news. You have a d15b7 engine. 102 hp non vtec beast. Stock DX engine. Sorry dude.

Not my engine, I got it off of bauleycivic's mini-me write up. I do have A/C in my DX though.
