You'll need a chipped ecu and tune properly for lean burn, you'll need to find a way to mount the driverside post. Tranny wise stick with the d-series tranny that is specifically for the ef so you can save on buying the cable to hydraulic adapter.

 

Hi there mate. Thanks for the reply. I have a p2j-003 ecu that came with the engine, so can I tune or use this one for lean burn or do i need a hondata 300 too?

I also happen to have a d13 manual gearbox. I can change the flywheel, pressure plate and clutch to fit the d15 engine. Will there be a difference in ratios if I keep it cable, what would the benefits of a hydraulic vs cable be?

As for mounts. So the driverside should have a d15 mounting and i can keep the d13 mountings on the other sides?

Thanks for the help

 

You'll need run the xtra wires for vtec solenoids, the egr and control solenoid, and the crank sensor. You can either the following: A) find someone to build your a custom obd0 to obd2a ecu conversion harness B) Repin the wires to match up to the obd2a ecu and also wire in the sensors listed above.

 

Hi there mate, thanks for the info, the thing is that I'm currently not running any ECU since I'm using a D13B2 carburated engine. I might need a CRX Vtec or Civic Vtec cluster with plug and wire everything new right?

 

Get a cable tranny instead of that hydrolic one, those cable to hydro kits are a PITA and almost never work right.

 

I actually have a D13 cable gearbox, but the 3rd syncromesh is a bit mushy, that is why I have to use the S40 gearbox since I know that's perfectly working. Anyone in here used a conversion kit either from Hydro to Cable or Cable to Hyrdo? Brands and prices?

Thanks guys

 

S40 hydraulic gearbox to cable

Hey guys, I'm planning to use the cable clutch instead since I don't want to go through a lot of hassle on mounting the clutch master and slave cylinder.

Will the following work: Hydraulic to cable - Actuator
so that I can actually use my cable clutch with a hydraulic gearbox.

I also found out that I need to use knuckles off an 1988 Integra or a civic SI VTEC to use the larger shafts off my D15B 3 stage vtec engine. Is this true or can I still use my normal front knuckles?

Thanks!

Axles will be the same, they sometimes had different spline counts on the outer hubs for Si vs STD but the tranny side is the same. Just reuse the old axles and you should be fine (this is if you are using the cable box).

 

Wiring Diagrams

Hi there, can anyone supply me with D13 EC8 wiring diagrams as well as the D15 wiring diagrams. I've been searching a lot and I found a Russian site with loads of P2J-003 pics but did not understand the diagrams. Also most links I found on this forums are inactive.

Thanks!

 

Hey guys, just bought a new fuel inject tank as well as a 255LPH fuel pump. I just need the fuel pump assembly (gold thing housing the fuel pump). Can I use a fuel pump assembly from an EG, EK or any other car? What housing fits in a civic ef 1991 fuel injected tank?

 

Hi there, an update to all. I decided to use the D13 manual gearbox to avoid lots of bs for the hydraulic part. I used the D15b pressure plate and flywheel, changed a bearing and fork and serviced the gearbox. Wiring on the engine is ready.

I finally got hands on the fuel pump assembly. Damn 125eur is steep for just an assembly, but I needed it badly so I just bought a 2nd hand one.

Next two-three weeks should finish the project. Then some exterior mods including rims and lowering

 

More pics too, this thing is super clean!

 

Will post some updates when I get home, currently really busy at work. Thinking of getting these alloys for it

 

Ok, so finally got the engine in and wiring. Didn't do it myself since I am no expert in wiring, but just to update you with the parts list. I also decided to use the D13 gearbox for the swap since it makes the swap much easier.

New Fuel Tank:

Fuel Pump:

Engine in place:

Exhaust and GL rear bumper:

Rims:

What I would like to ask are the following:

1. what is the best air flow piping to connect to the throttle body?

2. Engine seems to be knocking (like when you push the gas pedal and revs go up and down) when on 3rd, 4th and 5th gear and idling. Is it the IACV or spark plugs?

3. What can I do to improve fuel economy (apart from driving routines obviously) - my ECU is a P2J-J11

Thanks!

 

D15Z6 with custom made intake on EF =]

 

Hey ppl, anyone know of a good trans for the D15B? I'm running on a D13 trans, and I'm pretty sure someday it'll go bad because of the synchros on vtec and stuff. Already changed the 3rd and 4th gears cause the 3rd gear broke and shattered the 4th one -_- What gearbox do you recommend? I have an EK3 gearbox at hand but that's hydraulic. Want something for power as well as economy and reliability. Thanks

 

holy hell that thing is 4x4 ef! you gotta lower that bitch asap :TU:

 

haha indeed mate, soon enough

 

If you can get you hands on one a DOHC ZC gearbox. Gives you access to equal length axles and if you swap in a 4.25 final drive will be super short gears.

 

Super Minty!

Lucky to have access to cars in such great condition.

In FL, we have no state inspection or MOT or whatever. So the cars here are RUN TO THE GROUND usually. They can barely drive under their own power let alone sit in your driveway without falling apart lol. Just jokin, but it's refreshing to see cars in that conditon (Same reason I love my CRV)

How was the ECU sorted out? If you were ale to find a tuner that knows his worth about your engine, you can push it further AFR/Ignition-wise on a Neptune or Hondata. But really not much more than the basic banter: inflated tires, well-maintained etc etc.

What's your MPG now anyway? You should be getting 50mpg (not sure what that is in L, I think 29 or something?) If not, on the verge of 60!

Really tuning is the key. I think Bone said was getting 40+mpg on a high comp D-series with "short gears" IIRC. But not just anyone can tune the low-cam, it is really a whole different beast...

 

Hmm good point, though if I get a ZC tranny, will i have to change axles and shafts? Thanks!

 

Yes. You would need to add a half shaft and convert to the larger style axles.

 

Hi there guys, it's been a while. I'm now converting the pedals to a hydraulic clutch and am going to use the ek3 gearbox. So let's hope it goes well. In the meantime, enjoy the current status of the car:

 

So, tiny update, I managed to create a hydraulic pedal setup, thanks to suja conversion and the help on this thread: http://www.d-series.org/forums/prod...t-reviews/154123-suja-one-sonem-ef-ed-cable-hydro-bracket-56k-die-slowly-2.html

Final result:

Ihave a major question. I'm trying to use a civic Ek3 gearbox (the one that matches my engine) which is hydraulic. I am confused to which mounting should I use. I drive a RHD car, so obviously it must adhere to RHD.

I found these but don't know if they fit or what exactly do I need.

EFDHCRH? - D-Series (EF) - 88-91 Civic/CRX (EF) - Civic/CRX - Mounts

Also right now I'm getting around 160KM per 20eur, which in my opinion is not that good, though petrol here is at 1.35e per litre. What is the best option to get more MPG apart from the usual maintenence?

 

Can anyone help me get the correct mount to use an EK3 gearbox on my Right hand drive Civic?
