VTEC-E .. 3stage D series vtec (civic vei) (jdm d15b) in AU??

[Dxs]

Kind of a broad question.

I have been looking into Vtec-E (which is basically just D series vtec engines, tuned/setup for economy rather than performance).

There are 2 variants.

The Australian delivered D15Z1?? That was in the 93-95 EG Civic VEI (only cam in 4 door here as well).

This had a 2 stage vtec.. but instead of high and low cams, it ran on 3 valve and then a pin went through the rocker at around 2.5K rpm to run the 4th valve as well.. this was just for better fuel economy.



now the second variant was the JDM d15b.. which had two sets of vtec, the 3 and 4 valve vtec setup as well as the traditional high and low cam vtec.

My point is.. is anyone running this JDM 3 stage vtec D15b? Or does anyone know if you can buy them from importers (i doubt any honda wreckers would bother importing such an engine??)

[ECU-MAN]

as far as im aware only iVTEC in the K range was 3 stage, JDM VEI is only 2 stage isnt it, like the AUDM

[Dxs]

i think it was in the Ek3

dual solenoid
roller rockers

i guess no one here is running one? They are obd2 as well i think, would be a little bit of a wiring headache

[EK1.6LCIV]

wow, dual solenoids interesting, I like this project have fun with it :)

[aaronng]

K-series has only 1 solenoid, hence 2 stage.

[tseesinngwailo]

These engines are capable of fantastic fuel economy, up to 28klm/litre!!! but when Vtec-Yo-ing it, also put out 130hp, you can get them imported, but most importers dont recognise them as a "performance" engine, you would have to slap some money down and get them to search for a half-cut for you, that way you also get the funky CVT gearbox that they came with, and all the wiring and computer bits u need. It could take some time, but the end result would be some sleeper fun

[Dxs]

so does anyone run the 3 stage d15b??

i am toying with the idea.. probably easiest to put into an EK.. they are all obd2?? Then import a jdm d15b and ecu.. and connect it up.. may require some basic wiring from the ecu to the solenoid setup etc?

[thepope1986]

CVT is homo. enough said

[hisoka]

doesnt d16y1 have this ? ?? not 100 percent sure

[dahon]

d16y1 is the performance d series engine i think... the one from the eg civic vti?
same as the d16y8 basically right? from what i remember... the one in the ek civic coupe (96-98, not the em1s im talking bout the ej8s)

theres also another vtec-e engine out here in aus, the d16y4 that came in the ek civic vti.. vtec-e (12v 0-2500/3000 then 16v @2500/3000)

yeh i was looking into the JDM d15b before(not to be mistaken for usdm d15b)... awesome engine... importing would be the most pain i assume... but dang that engine would be worth it i reckon...
from what i hear the cvt/multimatic tranny that came with the d15b was pretty good compared to the other cvts we have here...

http://asia.vtec.net/article/d15b/ look about halfway down... says they came in the "EK3 VTi and Ferio Vi"
i love this part... duno if its true though...
"Manual Ek3s have been clocked to do the standing 100kmh dash in low-9s, faster in fact than an automatic transmission EG9 or EK4 B16A Civic."

i think it was in the Ek3

nice link, Iv never seen the dual solenoid setup before,

no reason why you cant wire it up if you have to

yeah,

but seeming as though there would be no d15b jdm engines in the country.. and it seems the manual ecu for this engine is a bit rare.. etc etc

big headache,

[tseesinngwailo]

Why not just get a whole half-cut, a CVT and engine would still be fun :) thats why i want one for my wife's car, she would never know of the vtec-yo hidden inside :)

[d15z1SUX]

the jdm d15b is not the 3 stage vtec. the 3 stage vtec is the d15z7.

actually there appears to be jdm d15b that have 3 stage vtec.

d15z7 is for 3 stage vtec outside of japan.

[dahon]

theres two types of d15b
the usdm and the jdm one... the jdm one is the 3 stage...
and the usdm one i think is a carby methinks...

[d15z1SUX]

theres d15b is australia too. its just the sohc non vtec in eg's. if its jdm d15b should have vtec rocker cover.

[dahon]

nah jdm d15b doesnt have vtec rocker cover i dont think... not all vtecs have the vtec rocker cover... my daily has a vtec solenoid (vtec-e) but doesnt have a vtec cover...

So it says -
"From around 3000rpm up to about 6000rpm, the first VTEC actuator switch engages and the previously inactive intake valve now goes into operation. The engine now runs in 16-valve mode behaves just like any of Honda's highly spec'ed 16valve PGM-Fi engines. After 6000rpm the second VTEC actuator switch engages the wild cam/rocker arm pair for the intake valves. This switches the engine into the wild-cam mode where it goes bonkers delivering 130ps at 7000rpm"

What's 130ps? How does that compare to say my d16y4?

I can't understand the power comparison because this is a carby car.

Oh wait,I saw this -
"EK3s with manual transmission have final drives of 4.058 with 1st & 2nd gear ratios of 3.250 and 1.782 respectively. Manual Ek3s have been clocked to do the standing 100kmh dash in low-9s, faster in fact than an automatic transmission EG9 or EK4 B16A Civic."

My automatic y4 is 10.5 seconds.

[d15z1SUX]

nah jdm d15b doesnt have vtec rocker cover i dont think... not all vtecs have the vtec rocker cover... my daily has a vtec solenoid (vtec-e) but doesnt have a vtec cover...

my vtec-e (d15z1) has vtec-e rocker cover lolzzz...

130ps is roughly 128hp or 96kw i think... or 98kw...

[Greylock]

i think u guys can try the Honda City models assembled in Thailand.. 7 speed CVT gearbox with D series vtec engine..very fuel efficient as i have one back in Malaysia!

[dahon]

my vtec-e (d15z1) has vtec-e rocker cover lolzzz...

lolz lucky bum!
my d16y5 has none... =( but the solenoids there so it better be vtec.. hahaha
but yeh the 3 stage is a very interesting motor... sux how its hard to source here.. motor, ecu etc.. would be a very nice motor to put into a tiny shell for a daily/fun
hehehe

[beeza]

atw :eek:
Mine is 70 :(

[d15z1SUX]

that sounds about right?

[beeza]

Yeah it's Automatic but needs a tune with greddy e-manage.

[hisoka]

whats a d16y1 then the auspec one ?? isnt it around 96kw~and its just single vtak

[dahon]

yeh they shuld be same power as the both have the high power vtec cam...
but it doesnt get super duper fuel economy... cos the d15b has the 12v mode aswell..

[hisoka]

i dont remeber it being that bad ?? lol is it really

[dahon]

d16y1 has good fuel economy.. but vtec-e manages to sqeeze even more out of it... especially when youre in traffic and barely get over 3000rpm...
couple that with cvt tranny and u barely even get over 2000rpm wen bumper to bumper...
u can pull off probably 5-6L/100km if ur super duper granny

[BO22IE]

Theres one here in Sydney. 😁
Imported straight from japan it has EG6 interiors and everything D15B manual.
Howmuch for this car in the market??????
