hello all, after picking up a 02p5 and not able to replace the knocking 2.0 I bought a jdm fsze think from what I read on the jdm site that it is a direct replacement. it even came with trans and ecu with harness. whoo hoo.... NOT. I have searched this forum and have now concluded that this is going to be a pain. could some one tell me how I need to go about this install? what is needed and how to used the jdm ecu weather to standalone or wire and how? yes yes I know should have just went stock but the engine but alittle miss info has set me down this path and I intend to finish it. I see a member called focus has completed this swap but haven't seen any how to threads. I apologize for my ignorance and would be extremely great full for any help.
 
Just to clarify: even though it is a JDM engine, it is not necessarily an FSZE. There was a guy on here selling parts from an "FSZE", but it was really just a JDM DE. Are you sure that this engine is, in fact, an FSZE? Not trying to talk down to you, but I have seen others make that mistake. Just don't want you to go through more work than you need to!
 
well that is a good question, but from reading the forums here i saw a picture of a ze and the black box on the intake that was said to be the tail tail indication that the engine is truly the ze. i also checked the ecu numbers and from what i read on the forum is supposed to be for the ze as well, both heads have fs9 on the casting. at first glance the engine appears to be the same as the one in the p5. then you notice subtle differences such as the black box on the intake. there are two vacuum noids on the p5 intake that are not on the supect engine and it only has one on that same side with two hoses ran to it. for the most part the harness would even "plug up" with a few changes to sensors. and sir i assure you if you can keep me from doing more work and saving me a buck or to i don't mine the scrutiny!!! If you could tell me how to tell the two apart that would be great!!! i guess i could always check the cams for the fsh9 markings. right?
 
If you want the full power of the fs-ze it will most likely be less work if you were to run a standalone instead of trying to run the obd1 harness that comes with the ze.

If you just want to have it running normally the stock de ecu can run the ze. It's just basically swapping over a few sensors and that's about it. If you want to use the intake manifold of the fs-ze ( which I recomend ) you have to cut up your throttle cable because it is too long. Totally worth the pain it is to get it hooked up properly tho. If not just swap the ze IM for the DE and you shouldn't have any issues. In my city fs-ze's are plentiful so it's common to replace the stock DE with a ZE

Personally though if I had the resources I'd just run the ZE with a standalone with a custom tune
 
My mechanic swapped in an FS ZE by mistake (thinking it was a DE). I've since confirmed it's a ZE (fsh9 Intake cam). However, he did not install the intake manifold, I did it myself. Perhaps DOMO has a slightly different set up, but I did not have to do any cutting of the actual throttle cable. In fact, it's adjustable - you just have to adjust to its limit length and do some minor cutting of the rubber dust boot with a nail clipper or something. Not really a big deal. Use this link as a good start up for the intake manifold install. Don't hesitate to message me if you have questions.

Also, my mechanic said the engine would not crank with the ZE crank pulley sensor, he had to use the DE crank pulley sensor.

Good luck.
 
great info guys, and for the record my engine is the ze . i picked it up with its auto trans. I would like to,in the future, instal a stand alone and have it tuned but for now installed and running is the goal. i know the peeps on this forum know tons more than i and would like to ask when the transition is made does anyone make a plug and play ? if not which standalone is the least expensive and user friendly ? ill be putting up pics of my build soon. lost domo, thanks for the fast response.
 
What will control the shifting of the auto trans? You may have to run ecu for trans and standalone for motor. That is the wall for me going much further into tuning mine having sportauto. I also have a complete ZE intake with fuel rail and TB and EGR tube that I would like to eventually incorporate into my build. Not expecting much gain over my P&P'd DE IM with VTCS removed but have the stuff and might as well use it. Also have MPI NA Tuner with Innovate wbo2 and gauge, FM voltage clamp & another header with 3 bungs in it for another project too but I digress and clutter thread so I'll stop now............subbed for auto trans angle on this thread.
 
as I understand that is what the "stand alone" does is just fuel and eng management, i have also seen some piggy back stuff and or integrated wire looms for the j spec ecu, the member called focus has done this as well as someone from a different site (don't remember which) and the tech that accomplished the integration from that site stated that he wasn't willing to tell how because of his time and effort to complete the task(had to translate japan tech manual) which i full well understand. as i have the eng harness and ecu I would like to try eventually
 
The motor will swap directly in, you can use your stock trans ecu and harness i can give you a partial list of what you need to do but it's been awhile so it might not be all of it
Use this from the de
Crank pulley and crank position sensor
Intake manifold
Harness
Knock sensor ( most people don't swap the knock sensor and get the pinging issue, they're different I can't remember how)
You can use the stock ecu but I highly advise the mp3 flash

It is also recommended that you get a wide band and fuel pressure regulator to richen it up a bit to compensate the ecu not knowing about the higher compression. And definitely run 93 octane

There may be other sensors as the fsze is not obd2. But I can't remember all the details

Stand alone replaces the ecu and controlled everything. Alternator, fans, literally everything. A piggy back will control fuel and some will do timing. You can do a parallel setup and have the standalone control just the fuel and timing
 
again ty for the info tweety, but do I have to change the intake? also dose any one know or recommend a stand alone and shop that would do a tune. I am not afraid of a lengthy road trip either, but close to Mississippi would be nice

If you're talking about the intake manifold: No you do not have to change it. You can run the ZE longblock with the DE manifold. It would be make for an easier and more straight foward swap. If you're strapped for time, I would just run the DE manifold now, and when you have time, get the ZE manifold ready for installation. The most involved parts of the ZE intake manifold installation are modifying the vacuum lines with T connectors (this is addressed in the link I gave you), and getting a flexible pipe for your EGR pipe--the EGR port on the ZE manifold is located in a slightly different spot. You can use the FS ZE EGR pipe if your swap came with it. Otherwise, you'll have to get gas lines with adaptors from Home Depot or the like.

In summary, if you're in a bind then put on the DE manifold and start driving it. I would recommend using the ZE manifold eventually though, as you already have it and it does give some noticeable mid-range torque gains--even with an MP3 ECU flash (which is what I'm running).
 
well another conundrum, I have auto trans !! how much does this hinder my mod effort? and to all peeps on this forum that have and are replying ty and merry chirstmas!!!

You can use your ECU with the ZE, when swapping over the tranny, you will need to use your flexplate & trans bracket...
 
I don't think a de ecu will run a ze intake manifold right. If you're just trying to get it runing use the de intake because the mp3 flash will not work with an auto

If you are going stand alone then use the ze intake. All the auto functions can be programmed in with the stand alone

As far as tuning, decide which stand alone unit you're going to use and then ask around locally and find out who has tuned it. You're going to pay for a good tune, the guy I'll be using charges 500-600 for just the tune if there aren't any issues that come up but I wanted the best and people travel 8-12 hours to have him work his magic for a reason
 
De ECU will run the ZE manifold with a couple of modification to the vac lines as posted earlier...
 
well I have removed the old engine and have it on the ground, i have removed the crank pulley and sensor from the ze. i am pleased that most things are a direct swap the trans that came with the ze is identical to the one on my de all plugs and sensors are the same so i am going to put it in as a unit. I had some trouble when it came to the fuel rail, the ze i have has rubber lines pressure and return and my de had the quick connectors and high pressure line. I swapped the entire fuel rail assm from one to the other with some modification to the black box on the ze my rail bolted up with no problem after that. i am planning to use the exhaust manifold that came with the ze as well. A small section of the pipe will have to be removed and refitted infront of the cat and I will have to put a bung for a o2 sensor but that is cake. the worst thing i have found is my de knock sensor is toast and i have to get a new one. I plan to have the ze in and running by this Saturday and see how many bugs i have to work out. i do have to say engine removal was a snap had it on the floor in like 3 hours lol... hope it goes back the same.
 
My workaround for the fuel rail connectors was to use the FPR from the DE and put it on the ZE rail, now with the new position of the fpr, fuel lines need to be switched...the one that connected to the fpr on the de has to be switched with the one that connected to the rail (but will now be used on the fpr) the other line cannot be used so I replaced it with about 8" of fuel line and appropriate clamps...
 
well its in and running great!! it was a straight forward swap with the exception of vacuum and a couple sensors. i did things little different mainly because my state isn't as strict with emissions. had alot of fun running away from my wifes stock 13 civic ex-l lol. if anyone has any questions about a ze swap i would be glad to try and help. now i just need some rims ......
