FS: JDM d15b VX motor sets
 

hello everyone,
i have for sale, several JDM D15B VX motor sets for sale, i have them in 5 speed and automatic. complete motor and tranny, along with all the accessories, $350 each.

california? I would only do pick ups, but am in nj.

located in canada, will ship to anywhere in canada and USA

NOW you tell me...

Damn, they made these things in auto versions in japan...

Do you still have the engines? Do they come with the wiring harness and mounts and stuff? How much to ship to Los Angeles California?

8civic8, I purchased my engine from www.nippon-motors.com

They have free delivery in southern california.

They usually come with the flywheel, clutch, intake manifold, exhaust manifold. Mine came with a distributor too. They'll usually have the plugs attached (when they were removed they just cut the wires). THis means you'll have to wire your harness yourself, but you'll have most of the plugs. I should be able to help you with any other plugs that you need.

If you need VX engines. The original poster is a good friend of mine.. He probably hasnt looked here in awhile. I can post his website if its ok with admin.

still for sale??

Contact 78si, the guy above you, and he can hook you up.

I hear there is a 3 stage vtec engine made in Japan that was called D15B. It was basically a hybrid of our vtec-e (like in the D15Z1) and the vtec that is found in the D16Z6. Are these engines just the Japanese D15Z1?

the 3.stage resembles more the usdm d16y8/y5 motors
it doesn't have the small intake and head chambers or deep dish pistons.
it also doesn't get the same gas mileage as the d15z1
and it has a much higher total output power
there are very few similarities...
actually i think there is only one identical part used on the whole motor.
the p07 rods

What kind of mpg differences would you see in one of the JDM motors as opposed to a D15Z1?

If I'm understanding correctly... they have lean burn at lower/cruising RPMs, vtec for top-end power, but the lean burn mode isn't as efficient as a D15Z1. Sounds like an interesting compromise, if the losses in mpg aren't too great.

Can some parts be swapped from the 'Z1 to make it more VX-like?

Ok, 3rd question. Is the D15Z1 also available as a low-mileage import?

The d15z1 is called a d15b in japan (which is the same name as the normal vtec model as well) but the vtec-e model is the same as our d15z1.

I've never dropped a motor in myself. Can anyone give me a ball park number to how much it would cost me to have a mechanic install it.

Hey I would love to get my hands on one, I live in Long Beach and just moved from San Diego. How much for an a D15z1 (is that what it is or is the 3 stage vtec, I only want the regular vtec-E D15z1)? What comes with? flywheel, ecu, tranny, A/C??? anything I could buy extra?

https://www.nippon-motors.com/honda.htm your in luck! they deliver FREE to socal from what I know this is a very reputable site.

Guys beware!! If your from the USA don't even bother buying this motor from Canada. I friend of mine bought a Supra 2JZ Twin Turbo motor from them on eBay and it turns out when he got the motor it was bad. He called them and told them they sent him a bad motor and they said too bad. He tried filing a dispute for the charge with his credit card but lost the dispute since they are from Canada.

So buyers if your buying from this vendor beware.

I bought one of the D15B engine/manual trans from JDMSource, and have been very happy with it.

Some side notes:
1. DOES NOT get same FE as the D15z1...I get 40-45mpg if I'm careful.
2. Rated @130HP, 7K redline, great fun when the VTEC kicks in!
3. I replaced my ECU with the PO8.
4. Need to replace the 5wire O2 sensor with a 4wire...haven't got to it yet.
5. All the sensor wires were cut on the engine I received. Would be nice if they'd unplugged them and left the harness intact.

40-45 is still pretty good, with a cx or vx trans i wouldnt be suprised if you saw closer to 50

just to clarify this thread a little
the 3.stage d15b was made in 95-00 in japan which corresponds to usa 96-00
it is NOT the jdm equivalent of the d15z1
which was 91-94 in japan...92-95 usa
for anyone buying a jdm d15b there are probably 5-7 variants of this motor.
japan simplifies the stamping.
88-91 jdm d15b uses the d15b7/d16a6 style head
92-95 jdm d15b vtec (unique crank & rods)
92-95 jdm d15b non-vtec
92-95 jdm d15b vtec-e
96-00 jdm d15b
96-00 jdm d15b vtec (3.stage)

and i think there are a few more

its also funny to watch people complain about not having a wiring harness
you all dont realize all the jdm cars are rhd and the wiring harness is 180? off from usa...making the wiring harness useless except for the plugs i guess.
but all the plugs are available off usa cars from different sensors.
you just need to learn how to depin the connectors...
its fairly simple if you take a minute with a care, some needlenose pliers, and half a brain
depinning the ecu connector i use a sewing pin...a bit harder to do.

also worthy of note...japan doesn't have emissions...
so no jdm motors are going to have purge valves if you use an american computer.
you will have to tee off one of the intake manifold ports for purge canister.
and tee off again for the purge valve vacuum source.
fuel pressure regulator would work for the purge valve.
and the canister i guess could tee from either the brake booster (before the one way valve) or the pcv line (before the pcv valve)

also to run a d15z1 or equivalent jdm motor you will need the egr controller
this is the black box on the firewall
few swaps will come with this...and it increases your gas mileage for sure.

That brings up a good question...I've thought about having the VX trans rebuilt (I still have the D15z1 engine/trans)...is that a big deal, who would be reliable/reasonable to do it?

Also, the jdm motors are missing the vtec solenoid oil pressure switch. I was scratching my head for a day or so wondering why I had an extra connector when I wired mine up with a US harness. So, you will need to purchase a oil pressure switch if your motor does not come with one installed.

What is the right ECU for a JDM D15b engine? Im having trouble trying to find out why my friends car failed smog here in Los Angeles, CA. The car passed the emissions portion fine, but failed because of timing. This is his car:

92 Honda Civic CX w/JDM engine swapped in. (car was bought this way)

ECU I think is a P05-A00

What could be causing the timing to make the car fail smog? He's going to the state ref to see what can be done with the car.

Thanks in advance for the help.

again
there are many versions of the jdm d15b
all of which use different computers
you need either the factory computer for the motor.
but if you are switching generation model of car / shell then you need the ecu that closest matches in that generation.
there are usually better options then others.
but first you need to know what motor you have.

its probably a 96+ jdm motor which has the obd2 cam gear and he is using an obd1 computer...
there are options but you must match the cam gear to the computer because 96+ timing in the computer is much much different then the 92-95 motors/computers...
putting a 96+ motor in a 92-95 car requires use of the obd1 cam gear.
the cam gears are offset half a tooth between generations causing over 9 degrees of timing at the crank pulley

He should find a P07 ECU.
