What cars (and years) did this engine come with? Are these motors to complicated to work on? I mean, are they more complicated (would have more problems) then other vtec honda motors?

It's the 3-Stage VTEC Engine. "This engine featured optimal intake valve timing and lift across the low-, medium- and high-speed stages, thus achieving ultrahigh fuel efficiency. Drawing on Honda’s accumulated technologies, it represented a major advancement on the original VTEC engine and employed various mechanisms to achieve excellence in fuel efficiency." (Honda)

I searched the archives, so please...:
"Your search for vtec-e returned no results.

Thank you in advance!

 

Civic HX.

The key is that it is made for fuel efficiency, not speed.

 

VTEC-E was used in the Civic VX (D15Z1) and has been used in the Civic HX (D16Y5, D17A6, ?) after that. The VX was of the eg hatch style so from 92-95. The Civic HX inherited the technology from 96 on. I don't know what year they stopped making the HX.

I have no idea how much harder it may be to tune it so I won't make a comment there.

 

I understand that it's made for fuel economy only... and this is why I am interested in this motor. How rare are these models you listed above? I don't see them very often. Do they differ in any other way with other models, lets say CX?

 

from what i understand is they were only released in certine states

all of you are wrong, if infact it is the 3stage, which i doubt, unless it got swapped in. look for two vtec solenoids. better yet, look at the block code, and tell me what it is. anyhow, the 3stage vtec is your run of the mill z1 block and bottom end (good r/s ratio, using 137mm rods) and destroked crank, and frankenstein head. the use 12v until the first crossover for MPG, run in 16valve low cam after the crossover, then at the second crossover hit the high cam lobe. basically a JDM D15b vtec w/ GOOD MPG. WOT performance is the same, ect etc. the only problem w/ them is if you dont use the stock ecu you will have trouble tuning it, a chipped ecu wont allow the vtec-e "lean burn" to be affective, even though you can make 12v,16low, 16vhigh work, it wont go into lean burn and give the ultra high MPG that a true vtec e would. anymore questions???? oh, and dont believe everything you hear, most people dont even know what vtec-e is, much less 3stage.

I understand what you are saying... however my questions need a much simpler answer... Don't get me wrong, the information you posted above is VERY useful! Thank you sir, I really appreciate your help!

Original questions:

i drive a Civic VX with a stock D15Z1 (Vtec-E) motor and i would have ended myself from boredom behind the wheel if i wouldent have blown the Vx transmission and had it replaced by a EX/Si tranny.

Problems i personaly have experienced:

-"lean burn mode" a mode the motor uses at a certain % of throttle position and lower. not bad at all, does what it is supposed to but when you NEED the power, it seems that the ECU takes a long time to respond to a upped throttle position % creating a sorta "struggle" or "hesitation" before the halrdly acclaimed "power" kicks in

-the use of a EGR: this is problematic because once it's clogged, it seems the motor becomes even more sluggish in leaving lean burn

-5-wire o2 sensor: stock wideband makes you really angry when you either want to swap motors or when you have fouled the original one (the motor runs like **** with a fouled o2.)

-Ultra-low compression: simply put, mini-me isnt as effective on the Z1 as opposed to another motor.

-total and utter lack of grunt: in it's stock form, the exaggerated 90 horsepower coupled with the amazingly long tranmission makes for a slow, but fuel economic car

the day i braught 'er home:

 

his isnt a z1 so all that info is null. the 3stage doesnt use a 5wire (its a JDM motor for god sakes), it also doesnt use an egr(its a JDM motor for god sakes)
OP, no differant to work on than any other sohc motor. mini-me swap will work w/ the 3stage because it doesnt use the dished pistons like the z6. and they came in 96-98 j-spec vehicle. i have no clue as to what car. of coarse all this is assuming it is 3stage and not a z1.

 

It is a Z1

Worthless motor IMO...I got one.

But Driving 250+ miles a week, it is fuckign awesome.

And the 3 stage Vtec, like other guy was saying is a d15b7? Not the d15z1, sorry.

I believe the JDM d15b came in the VTI...i think.

 

i have a vx,really rare were i live (many people didnt know there was a vx in 92-95 )
looks like any other d series engine but i cant tell you more than other people said

You have the Vtec-e valve cover?

Cause I do

Yes, Ive seen maybe 2 otehr VX's in my area...and mine is BY FAR the cleanist...the otehrs r driven by people who dont give a ****.

But glad to see it has 400k on it, and is still ticking...Im only at 185k.

But yes, the car is VERY slow...but I hit the highway throw the bitch into 3rd,a nd ride it all the way to 110mph...I lose EVERY single race from a dig, after 1st...2nd gear is just a dog. (I dont really race it...)

I have raced an older accord 91-93, 5 speed, on the highway, up a hill, into the wind, and won! Thats a feat for my 80hp monster!

WTF are all of you talking about, this dude asked about the 3stage vtec motor. even the things you are saying about the z1 is wrong. sorry, im in a bad mood, but geez get the facts straight before telling someone something completely wrong.

 

I looked at buying a VX last year, the one I looked at was a 93... it had an EGR valve and a 5-wire O2. It also had a lower redline than comparable SOHC engines. If I were to go for the VTEC-E now, I'd probably try to find it in an HX or something. I just want those spiffy super-light alloy wheels.

So go beat your dog, come in here with some evidence or wtfever you want...we dont care if your in a bad moood...get over it.

The whole thread got off topic when people were thinking the z and the b were the same motor, they are not...which you obviously in all your glory already know.\


Id like to know what I told is completly wrong sir...also.

 

Schurke your asking about 2 diffrent motors, vtec-e is the economy version of vtec, not sure what models it came in. From the bit of research I've done (I could be wrong), the only 3 stage vtec is the JDM D15B that came in VTi/Vi models from 96-00.

And yeah, 3 stage vtec is a combination of vtec e and power vetc.

now, i wasnt talking about you inparticular, rather this whole thread, everyone is talking about the z1, if you read the OP you will see he said "3stage vtec" so everything that was said after that about the z1 was pointless.

 

search for threads by bense hes makin a high output HX motor

 

umm, not really, its a high output gx motor w/ vtec-e head. but basically a high output vtec-e motor.

 

civic 2000 HX -d16y5.maybe others too i dont know...gas saver..when vtec kicks in it shuts down one of the cylinders so it runs on three instead of four..cant really do much..most EX parts fit as far as mods go
