i just recently found out about this engine and its 3 stages of vtec and 130hp.
can someone help me out finding as much information on this engine as possible.
ive searched, but no solid information.

and also do you think it would be worth seriously building?

"SOHC VTEC-E
Honda's next version of VTEC, VTEC-E, was used in a slightly different way; instead of optimising performance at high RPM, it was used to increase efficiency at low RPM. At low RPM, one of the two intake valves is only allowed to open a very small amount, increasing the fuel/air atomization in the cylinder and thus allowing a leaner mixture to be used. As the engine's speed increases, both valves are needed to supply sufficient mixture. A sliding pin, which is pressured by oil, as in the regular VTEC, is used to connect both valves together and allows the full opening of the second valve."

anythingg elseee?
cmon i know you people know more!

obd1 d15b vtec-e = d15z1, 92hp

have fun!

What do you need to know? That it's a cheap, gas-efficient, small engine that Honda put in certain cars to test out fuel economy theories?

I have this motor, and i cant get over how loud the VTEC engagment is. When it was installed and wired up correctly, most of my friends who were there have DOHC motors, and when they heard me take it down the street and try out vtec for my very first time, they were more than amazed and stoked at how loud it hits. Its an awsome motor.

Basically heres the idea

Stage 1: idle-~2700rpm runs 12valve mode, which creates a leaner-than-usual burn so it saves on gas.

Stage 2: 2700-5600 runs normal 16 valve mode, for moderate driving and acceleration.

Stage 3: 16valve VTEC @ 5700 rpm, hits louder than any stock Single cam motor that i have EVER heard, and pulls pretty hard to whatever your ECU's limiter is. The motor puts down about 130ish at the crank. Its a great motor for a stock SOHC. JDM powa! lol

One issue tho... Finding the Right ECU. I had and still am having a hard time locating the correct ECU. Many sources have said its the P08, but im still not sure if that is correct. I myself am running it fine just for now using the y8 computer, just a CEL for no second 02 sens, with very near plans using a P28 and adapter harness.

The only thing i had to swap on the motor was the dizzy, and the Intake manifold, to a Z6 one, cause the factory utilizes an EGR valve, which USDM honda motors ( as far as i know for recent ones) dont use.

Exactly, it's one of Honda's most efficient motors. It gives you great gas mileage and a little punch when you need it.

By no means a performance motor, BTW.

Yea, i get amazing highway mileage, once hit 378 doing highway miles. Its not exactly a big performance motor, but i must say, hitting VTEC is very fun, hits as loud as any stock DOHC, and has a nice punch to it, but as always its still a SOHC.

its not a motor worth bulding?

what single cam is worth building.
i mean im not looking to make insane power, but if i decide too i want to use that motor.

i want to build a single cam because i like being the underdog

It would be if more parts were available. Unfortunatly replacement parts are all that exist. I beleive Zex makes a Camshaft that elimiminates the first stage, and runs a more agressive 16 valve mode, and a stage one VTEC. Other than that, nothing internal really, but all D-series bolt-ons and Tranny parts work. I personally have the Z6 trans and Fidanza Flywheel (awaiting install At the moment), cause i wanted to give it some more "fun" factor.

If your really looking to build a motor, go like D16Z6 and boost, or build a B series.

iheartjayDem

yeah my friend has a z6 thats hes starting to build.

second option is b20vtec turbo

mmm... CrVtec

leroyb

jdm d15 are the **** a have one too and i have ben beating every si that steps up

iheartjayDem

a homie has y7 with a z6 head.
he has i/h/e and chipped ecu and he takes gsrs all day long.

i love when people get underestimated.

Any actual gas mileage numbers will be appreciated.

97 ej6 the reason vtec is so dramatic is because you are going from 12 valve to vtec instead of 16 valve to vtec. if you were using the right ecu which is a p2j ecu it is a smooth transition from 12 to 16 and then 16 to vtec.

Im more than aware of that, lol. P2j you say? where could i find one of these?

oneludesol

for some reason, i feel that your motor is either operating in 12 valve mode all of the time and activating 16 valve non-vtec mode at 5700 and thats why its so loud, or running on 16valve all of the time with vtec crossover at 5700 like a normal y8. I say this because if you are running a stock y8 ecu, it doesnt know to actuate the second solenoid so it just deals with the first, just as your y8 ecu has no output for EGR, it has no output for the extra stage. Correct me if I am wrong, this is all just theory, I want to do this swap and would really like to find a way around hunting down the right ecu. I was thinking writing a portion of crome to actuate the 1st stage...

Oh NoEZx 3 StGes oF MaD VtAKK AkTIoN!!!!!!

iheartjayDem

haha hail mo' ******' yeaaa.

p2j ecu is the right one.

i used the search button
haha

Bejita

BE CAREFUL!!! YOU DONT WANNA BLOW THE WELDS ON THE INTAKE!!!

oneludesol

during your search did you come across how fuking impossible it is to find? LOL

iheartjayDem

haha i wouldnt doubt it.
anyway to get it reflashed to those specs?
