i hade a d16 i blew it out now i just bounght a jdm d15 it seam too have 2vtcsolenid wats up with that????????can i connect it or du i have to put it from my old motor

deryck324

does it look like this

leroyb

yea but it dous not have those plugs at the end

leroyb

any one knows wats up

hmtcrxsir

jdm **** but different OBD

eg8tuner

i believe the the jdm engine as duel stage vtec

but i could be wronge cause i know only bits and pieces about jdm engines.

leroyb

is that any better than the old one will it pass smog

eg8tuner

wouldn't know there r no emissions in maine other than your check engine light has to be off. o and no more test pipes were your cat was.

when you put the jdm motor in i would assume you would need a new ecu but you can probly search to fine a thread on how to wire it and what ecu to use.

leroyb

i dint get all the pipeing just the long block

eg8tuner

ok so you got the block internal head and intake manifold right?

if so you would still need to run a new ecu because a USDM vtec only has one vtec solenoid and this engine has two that i believe open at different times so it alls o has two solenoid wires that would each need there own pins in the ecu

just out of curiosity all so what is the rest of the engine code on the block

leroyb

so if i want it to pass smog i would be better off with my old engine??

that kind of look like my friends auto transmittion

YOu have whats called the JDM D15b, i have it as well. Its a 3-stage-vtec motor, yes thats right, 3 stage. U need the right ECU to make it run right, but it will run fine with any VTEC ecu.

Heres the scoop

stage one, idle to 2700 is 12 valve economy mode
2800-5600 is 16 valve regualr mode
5700-rev limiter is full on VTEC

The thing i love about the JDM D15b is the agressive cam lobe for VTEC. My friends have constantly told me that it is the absolute loudest VTEC hit for a stock single cam they have ever heard. I would hands down bet money that it would give a USDM B16's VTEC pop (in terms of loudness) a run for its money, no joking there. The idea behind the engine is the use of both fuel economy as well as performance.

The right ECU is the P08 unit, it is an OBD1 motor, although the shape and size resembles that of a Y8, for example, the valve cover looks liek a y7\y8, the intake Manifold resembles that of a Y8 especially, as opposed to the B8 and B7's and Z6's.
Im currently running it with stock 96-00 EX wiring harness and ECU (p2e) and it runs great. This motor works best with a y8 or Z6 trans..

One thing that must be addressed is its EGR system ( exhaust gas return). Since it was a fuel efficient motor, it made use of a exhaust return system on the intake manifold, and a sensor that looks very much like a Blow Off Valve. THis sensor has a 3-pin connector that looks allot like the map sensor could plug right in, but in america we dont use that system, so leave it unplugged, OR* Throw on a Y8 Complete intake Manifold.

Hope that was a help.


OK, so your solution... the VTEC wire connectors dont match up, so heres what you need to do. Manuelly connect ( and safely seal, either crimp or electrical tape) the Red wire and the green\yellow wires on the harness to the solonoid.
Next, take the black ground, strip off a tip on it, and ground it to the closest VTEC solonoid Mounting bolt on the block. As alawsys, save the un-used wire plugs, they may come in handy later if you end up swapping the motor out again.

good info. Do you have pics by chance?

3 stage vtec.

will it pass smog????????
