Hey guys, 

 
Long story short, I have been planning/wishing/hoping that one day, I could jam an EZ30 into my gen 3. There are a lot of easier, already done, and probably more financially viable options (gen 4 Spec.B H6, H6 Outhouse etc etc) but none were really what I wanted. Wagons don't appeal to me, and I'm fond of the way the gen 3 is. That, or mentally disabled. Either way.. 
 
So, after being told to do it by about 100 or so people, my dad and I decided that, after some research here and there, we could do it. 
 
After a little while, we acquired the required ( :P ) EZ30D from a wrecked Outback.   :D

We put the engine on the engine stand and did an inspection. Despite some average looking oil (bit dark but nothing else), the clearances on the engine and timing hardware looked good. 

Time to drop the boring EJ251 and 4EAT combo out.

Gettin' ready for it.

Ew.

Yay!

 
Next up, we had to start getting wiring. At this stage, I had little to no experience with physical Subaru communications systems. So naturally, we took the primary bulkhead harness with the dash harness, engine harness, and the last one we got was the front main harness, which is for the fans, lights, and ABS system as well as fusing. 
 
After that, I got the transmission stuff from a friend. The box is a 5MT Dual Range. Standard transmission conversion kit with the stuff and like. 
 
So the total list of parts looks like this:
 
- EZ30D with all accessories
- 5MT conversion kit (gearbox, shafts, clutch + fly, primary and slave cylinders with lines, clutch and brake peddle, rear diff and crossmembers)
- Full 02 Outback H6 wiring harness (dash loom, bulkhead loom, engine loom and front loom)
- ECU with matching Immobiliser and key transponder (MUST ALL BE MATCHED)
- BFM H6 cluster (attached images of pre-done cluster and expectations)
- Manual interior trim (only one piece has to be changed, lol)
- Outback ABS Pump and module to match harness
- H6 radiator and lines
- H6 fans (these are SLIMMER and more powerful fans than the EJ25 ones, which will not fit with the EZ30 installed)
 
...and to contrast how big of a job this is, I've probably forgotten a fair bit. I honestly don't know if it would even be easier to keep the auto, lol. 

 

EDIT:

 

I decided to finally begin with small tid-bits of information and such to try and help those of you after info. 

I'll start with..


THE GUIDE TO THE END OF YOUR LIFE (OR AN ENGINE CONVERSION)

Part 1. Fittin' stuff.

1a. Mounting.

So, first things first. Let's get it clear that, mechanically, this is easy. The EZ30 uses the same engine mounts as the EJ engines, make a swap fairly simply. One thing I've noticed is often missed, is that the Outback chassis uses 25x40mm steel bars bolted to the chassis rails to make the k-frame sit lower due to the EZ's bulk. These use the same bolts that hold the k-frame to the chassis, but are longer from the Outback to accommodate. 

 

YhMWn65l.jpg

1b. Gearboxes.

If it fits on an EJ, it fits on the EZ. End o' story. Same said with flywheels and clutches. 

 

UoOFlRql.jpg

Part 2. Differences between the Liberty 2.5 and the 3.0 

Firstly, we'll look at the primary differences between the engines. The EJ251 and EZ30D don't really share anything other than, they are both boxers and they both have a cast intake (and even THAT is difference on the EZ). The EZ uses a variable geometry intake (only applicable to 1st gen EZ) which the ECU is trained to take advantage of using low and high RPM modes. The changeover occurs around 3,500RPM-3,750RPM. The EZ also has a 24 valve, quad-cam, chain-driven valvetrain as opposed to the EJ251's 16 valve twin-cam, belt driven valvetrain. Other small differences include top-feed injectors on the EZ as opposed to the EJ25's side-feed injectors. The EJ25 also uses a coil pack with leads as opposed to the EZ using a coil-over-spark config. 

Part 3. The nightmare. Okay, it's not THAT bad but it is wiring. (Not needed for H6 AT swaps)

 

The main bulkhead

 

Not much to be said here, really. This is the main piece of wiring that will have to be swapped. 

vBkhhFPl.jpg

The inhibitor harness

Ironically, there's one main piece of wiring primarily responsible for making sure the car can run, and that's a small loom that you'll find connected to the shifter module on the side of the auto gearbox. This is called the inhibitor harness. I'm not going to screw around trying to explain it, just do this. People call the plug you'll be referencing plug "T3" but it has "B2" printed on the side. The layout can be found in the A/T Control System for the 6-cylinder engine with/without VDC (I used page WI-53). 

So, bridge wires found on pins 1 and 4, following the pin out on the service manual section I've attached. This will make the car start. 

(remind me to check the power wire for the VSS - it has 5 volts)

That's pretty much it.


The VSS for manual transmissions and gauge cluster wiring for it

The VSS is a small thingy attached the side of the 5MT Subaru gearbox. It has three pins, signal, power (+5Vdc) and ground. The ground can be attached to the nearest bolt, whereas the power has to be attached to a wire on the inhibitor harness (due to edit). The signal, I personally recommend, should be run directly up through the firewall and connected to the cluster. 

 

When I say that, you're probably thinking "Well Tim, that's just dandy. WHERE?! THE INTERNET SAID PIN 13 ON CONNECTOR i10 AND IT'S WRONG.  :diablo: " That's because that is exactly what happened to me because I was following a USDM forum and they have different looms. Easy enough. On that page we were referencing for the inhibitor harness, it shows a connector called "A: i10 (GREEN)". This is a gauge cluster connector on the pretty new wiring you've painfully installed. Pin 11 (eleven) on connector i10 (or as I eloquently called it, "the big c**t") is used for the VSS on an MT vehicle. 

And that should do it!

That's a purdy lookin' cluster..

The transmission control unit

Chuck it out. 

That ends the guide for now! If there's any questions, please post or message and I'll try to help! 
 

After all that, let's look at where the project is at the moment. Please let me know if the images aren't working and I'll fix it up. Images embedded now. 

 

Yes, I have to go through and add descriptions everywhere haha.

 

Odds are, I'll add to this post a lot and hopefully answer any of your questions! thanks yo!

Okay, for tonight's updates!

Picked up the new STi Genome strut brace! Woo genuine stuff! 

Flywheel, clutch and clutch cover is all nice and on tight, and the gearbox is now mated to the engine! Hopefully this time I won't bloody squirt myself in the eye with the slave cylinder!  :dash2:

Thanks for the response guys :) I'm probably going to use this thread as a sort of guide and make another for the finished product.

That's the logic! :P 

Updoots again!

 

Nothing major this time around, just some wiring tidy-upping and running the main connectors to the inside of the car. 

 

At this point, the car is basically ready for running gear and assorted fun stuff. :) 
 

New brake booster and pedal fitted too. Maximum yay!

Great advice, especially important to listen to when you feel like burning it and walking away ;)

 

"Interesting" about not liking wagons... Anyway!

 

Keep up the good work (and the pics!).

 

Cheers

Okay so maybe it was a slight fib about wagons, I just know that if I had one, I would not hesitate in making a custom sub-box and cramming two Sundown ZV4 15's and a US Audio Bonecrusher 9K in the boot.  :dance:  :dance:

 

Anyway, lightened updates!

Not much has been happening due a bathroom reno taking time up! Nearly finished though. Basically, have fitted the clutch pedal, rest plate from the manual (auto one was a bitch to remove!) and of course, the clutch master cylinder. 

At this point, we are basically ready to drop the engine and the 'box in and start tuning etc.

I've decided that my next thing will be an aftermarket ECU of sorts, and have been spying the Link G4+ Xtreme or the Storm, and using my spare ECU to make a patch harness for it so it's slightly plug-and-play. Of course, this will be justified due to other plans which are also taking shape. 

More on that later in time of course. :)

Okay! Time for numerous updates! 

There's a list and I'm going to update the main thread as well. 

So far, I've nutted out and found all of the wiring issues that have popped up. Most were a case of PEBCAK in a manner of speaking (like plugs not connected etc) but there is a few things I'll add to the main post to make things easier for those who are stupid, like me, and want to do the same thing. 

For now, enjoy some pics.

And there it is. The physical manifestation of my constant ramblings, rants, research and purchases over the last year. 

I barely even know what to say. 

After getting a tune done by Matt McLeod and having a bunch of auto junk deleted, it runs beautifully. We had a minor hiccup with the IACV being sticky and still have an O2 code, but otherwise.. 

It's basically good to go. Next up, panel beatings and spray paint. :) 

And this is what it sounds like: 

Have some pictures.
