The black red wire, pin 1 of the same connector, supplies fuse 13. May not last but it's a nice thought. ... JDM 2000 2002 Subaru Legacy 3.0R Outback 3.0R Tribeca H6 EZ30 Engine 6-cyl. Since you seem to be staying with the auto trans, that will make it simpler (relatively speaking). I spliced the green/black and brown/yellow wires to the other side of the resistor. The black blue wire at pin 64 (third row) of the EJ25 ECU goes to the tach. At that time it was flagman Subaru motor, its displacement was 3.0L, therefore they installed it only on the largest cars. That pin on the sender reads about 1k ohm to ground. H6 exhaust hits the 99 trans crossmember on the driver's side. By far the hard part is merging the EZ30 engine harness to the Impreza dash harness. On a side note, the turn signals won't work if you don't have the hazard switch plugged in. I have read that pin 8 B134 should be grounded in N, 5V in drive. Tuning the Subaru EZ30 H6 Engine; The Subaru EZ30D – Super Smooth and Powerful. Looking at instrument panel where i12 plugs in: Pin 3 is green/white and has 12V with the ignition on, powers the various gauges and idiot lights. is this reasonable or am i gonna regret it? Exhaust will go to the driver's side anyhow, so I'll just tweak the stock system for now to fit. I also kept the dropping resistor which was bolted to the passenger side strut tower. I would recommend this, if you want a manual trans, swap one in, you'll probably need to swap the rear diff too, still less work and expense than an engine swap. Anything under 120 ohms seems to read 210F and should turn on all the fan relays. The engine/ trans will bolt in- that's the easy part. TJ 99 LGT H6 Limited OBP A little bit of Wrx, a little bit of 2.5RS, a little bit of STi , a ... With a manual swap the TCU is wired to think that it is neutral full time. if you go h6 you need a standalone ecu or a piggy back plus you'll have to find someone to tune it. The 2002 FSM seems to have the right wire colors but the pinouts for the instrument cluster are different than the actual gauges. It seems like a lot of people, including in the thread above, do a harness merge. This engine was put into production in 1999 and it is a successor of EG33. The brake pedal switch is normally closed going to the cruise control module (CCM). The other side of fuse 11 goes to the green red wire, pin five of the "ignition" connector. However an inexpensive engine does not mean an inexpensive project. The supercharged gen4 h6 is no longer with us! The green black wire that goes from the transmission control module (TCM) to the CCM pin 3 is for vehicle speed. Totaled : … The FSM showed one of the wires going through the battery idiot light. The temp sensor reads about 3k ohm at room temperature. I think I just cut that wire and haven't had any codes since. It helps to put a jack under the front of the trans so the engine isn't holding it up while you're trying to separate them. The biggest downside is that it doesn't turn off at full throttle. For more info on the car, check out my build thread: http://www.ultimatesubaru.org/forum/topic/144953-long-travel-outbacks-or-making-subarus-faster-and-more-reliable-offroad/. It is grounded when the oil pressure is low. or the thermal overload is open, the relay won't have 12V. Easy way to do this is to go from the big green wire in the 2002 harness (see below for a convenient place to shove a spade terminal in that) to the harness of the car you're putting this in. This involves taking the harness out of both cars and combining them into one. A few times if we didn't have the grounds for the TCM hooked up it didn't work. This resistor goes between the light green and yellow/white wires at the TCM. I would recommend 1000 ohm 10W or they will get pretty hot. This is for the fan relay and sub fan relays 1 & 2. Here are the fuses we needed: The big green wire, pin 8 of the first gray connector, supplies fuses 11, 17, and 18. 06 SUBARU WRX STI V9 TURBO ENGINE HARNESS ECU INTERCOOLER JDM EJ207 LOW COMPRESSION. So I spliced that into the red/white wire coming from the EZ30 ECU. I wired up a four pole switch to ground the AC compressor relay, fan relay, main fan relay 1, and sub fan relay 1. You do that by grounding the green wire to pin 8. The EZ30D was designed as a replacement for the EG33 engine. Swapping a 2.5 RS for a 3.0 H6 in a 2001 Subaru Impreza RS. If not you will get codes P0743, P0778, etc. Went through this and my notes and I think all the information is here now, added a few things to the first post. By The 99 system is pretty simple. Red yellow and red are for accessories and ignition, so we plugged 12V ignition into both of those. The 99 is pretty simple so it was fairly easy to hotwire the AC. One of the big hassles with figuring this out is that the 2002 FSM only shows the wiring for VDC cars, and that TCM has three connectors whereas ours has only two. I do get some trouble codes related to evaporative pressure, fuel temp, and I did get a mixture lean code once. The engine/ trans will bolt in- that's the easy part. 2 talking about this. I have read what info i can find about the swap but its fairly limited. Subaru EZ36 engine problems and malfunctions. 2000-2002 subaru ez30 3.0l h6 6 cylinder engine, outback legacy tribeca 2000-2002 SUBARU EZ30 3.0L H6 6 CYLINDER ENGINE, OUTBACK LEGACY TRIBEC... Special Price: $945.00 There are four important wires going to the back in one connector that will cause trouble codes aside from the fuel level. The green/black wire disconnected will cause a P1400. There are at least five wires going to the 2002 ECU related to AC. I would totally be into this. I would recommend 1000 ohm 10W or they will get pretty hot. Even if the battery idiot light burns out, there is a diode going to one of the other circuits in the instrument panel that will keep the alternator charging the battery. Make sure you have both bellhousing dowels in place in the engine or trans. We’re mostly interested in the more advanced, second generation of this engine produced after 2003, however, will touch on the original variant. Eventually I just wired the brown / white wire that went to pin 27 of the 99 EJ25 ECU to pin 25 B135 (brown/black?) The red green wire at pin 58 (near center of third row) of the EJ25 ECU is grounded when the MIL/CEL is on. The engine has been running great, no stalling or anything, makes decent power. This first post will cover the wiring. One of the last wiring projects was the air conditioning. jdm subaru legacy manual transmission ecu h8 tcu ez30 rhd (right hand drive) wire harness #2. oem rhd (right hand drive) wire harness. ). This is in the middle of the normal range according to the FSM, and I've read other people have done this. The easiest thing to do is to splice the white/blue and white/green wires together near where they plug into the trans. To top it off, the TCM I/O signal chart in the 2001 FSM shows the pinouts for three connectors. pontoontodd, February 27, 2017 in Subaru Transplants. So I wired a resistor instead, alternator charges and no fuel level code (usually) with this. I guess standalone is most likely the way forward, but if this avenue is possible then it would save a huge amount of work. Originally I'd wired the VSS from the manual trans to VSS1 for the auto trans and never got a VSS out to the speedo/ECU. a wrx swap is so much easier and you can do so much more with it. By far the hard part is merging the EZ30 engine harness to the Impreza dash harness. Donor car: 2001 Subaru Outback LL Bean ed (EZ30D: 3.0L H6 rated at 212 hp/210 ft*lb) Recipient: 1999 Subaru Impreza 2.5RS (2.5L H4 rated at 165 hp/167 ft*lb) -I've kept the car is mostly stock up to now (aside from the interior) so this thread will pretty much only be about the engine swap. Pin 10 is violet or white/green and goes to the temp sender. Long story short I couldn't get it to ground the AC compressor relay. We're swapping an EZ30 H6 out of a 2002 Subaru Outback sedan into my 1999 Subaru Outback (EJ25, five speed manual). That is wired into the circuit for some of these shift solenoids, see page WI-52 of the 2001 FSM supplement 6 cyl. The transmission and instrument panel wiring do not match the FSM, so that added to the challenge. I guess if you're doing a manual trans swap into an H6 car, just pull out that bulb or cut the wire to the idiot light. Engine mounts line up perfectly in the 99 crossmember. If you don't have the red/light blue or black/yellow wires hooked up, you will get P0183 fuel temp sensor A circuit high. its a full teardown ordeal. Starter wiring is the same.The wires for the ignition switch on the 99 plug right into the harness of the 2002 even though one is four pin and the other is six. Flywheel and clutch from the 99 bolt right up to the H6. Seemed like the main reason to have the dash plugged in was the alternator wouldn't charge without it and it would cause the fuel level code. Is it that crazy? They both are on connector B21 going to the EJ25 engine, the pinout is as follows: Pin 9 is green or green/white depending on which side of the connector you're using. After all, ECUtek do cover the ECU for the EZ30 engine. It does have a head gasket leak, the yard I got the last engine from has a 90 day warranty so I plan on replacing that soon. After we put the 2002 harness in the 99 my friend realized we only needed a few fuses on the interior 2002 fuse block, so we cut that down. For engine or trans swapping purposes, the 2001-2004 non VDC cars are the simplest. don't. It's easy. But we already had a 2" thick core Mishimoto in the 99 that I really wanted to keep. If you cant find what you need here, I would go on rs25.com and post in the swaps thread. That was very easy to wire up and works great. Ivailo Ivanov. Subaru EZ30 engine reliability, problems and repair. We wanted to use the accessories on the H6 since the pulleys are different and it would make things much easier. The speed sensors in the auto trans must have a different output. I have been involved in building racing cars since 2003. The easiest is just to buy a decent H6 Subaru. It was designed and intended for installation in heavy vehicles of Subaru brand (SUVs, etc. Official H6 swap thread FAQ What are the major issues in this swap? I put a 1k ohm resistor in the harness plug and the ECU reads 109F. Subaru EZ30R Pro Series Engine We’ve recently started building more and more of these, so I thought we should share some build pics. 799.00. sold out. Make sure to get one of those and not the VSS though. I had a 47 ohm resistor between the 12V ignition source and the alternator. If you want the wipers, power mirrors, and other accessories to keep working on the Subaru you're putting this in, you'll have to power both the ignition and accessory circuits. The 2002 system is much more complicated. To test the fans, you can put a resistor in place of the temp sensor. I believe that circuit opens when the alternator starts charging, which normally turns off the battery idiot light. Newer Generations of Subaru discussion 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX Notes from EZ30 engine swap with JDM I didn't wind up doing it this way, but since the 2002 FSM is inaccurate regarding the instrument panel wiring, here is a little info on that. This is the most helpful thread on this swap I've seen: http://www.rs25.com/forums/f145/t155496-dynes-1999-2-5rs-h6-ez30d-swap.html. I bought a donor car and we pared down the wiring to the minimum needed to run the engine with no codes and keep the cruise control and alternator working. The main thing you need to do is bypass the neutral/park switch for the starter wire. Pin 12 is red/white and goes to the MIL/CEL pin on the ECU. The radiator setup will be another tricky part. If you are looking for a well known swap, with lots of documentation and the ability to add a bit of power down the road, the ej205 is a good choice. Exhaust from the H6 almost fit the 99, some modification will be required. The new motor is producing 250 horsepower to the wheels but the owner’s goal is to make 313 horsepower. That wouldn't be too hard to do, but I haven't bothered. Since we'd plugged the ignition switch from the 99 into the 2002 harness, the 99 harness end was just hanging loose. Subaru EZ30 3.0L Engine Review The Subaru started production of 3.0-liter six-cylinder boxer engine the EZ30 in 1999 instead of the EG33 motor. If you are looking for a car that's decent at lugging itself and a bit of weight around town, and never wanting to exceed the stock engine power, the ez30 with a bit of fabrication is a good choice. *-power steering pump needs to be swapped with impreza unit do to clearance issues*-wiring. If you're not running in a lot of dust like we do, you can skip this. Howling H6 Ez30 engine, 6 speed rwd transmission from a Subaru BRZ swapped into a 1998 Legacy GT.

The ECU also runs the radiator fans. There is normally about 3.5k ohms between these, so I wired in a 3.2k ohm resistor. At some point that was replaced with a 3.0 L EZ30 flat-six from a Subaru Legacy 3.0R. Throttle cable hooks up, even has the right amount of throw. My first car project was a 1991 Peugeot 205 Cabrio. The first thing to consider This engine has the same problems as EZ30, HERE you can learn more about them. i get the passion i have a svx an impreza and a loyale turbo. As I understand it, this is the only way to use a later EZ30 or EZ36. I need to update the wiring info a little when I get time. here is a datalog I really got to rewire alternator before doing mush else, TPS still giving terrible signals. I'd recommend using the H6 radiator as the radiator hoses will be much simpler that way. So the pinouts are completely different. You need to be a member in order to leave a comment. If you could re-write the full code to take the extra cylinders into account? Final confirmation was cutting them and then grounding the CEL/MIL and oil pressure to see them light up. gonna attempt to swap the engine, trans, and rear diff. Not sure about the overall powerband though, it could be worse. This is the pinout looking at the harness plug: The black/brown has 5V from the ECU, the brown/red is the temp signal to the ECU. on the 2002 EZ30 ECU. Easiest solution is to short this. I forget what color that one was. The H6 is definitely longer, maybe only an inch, but there is no way any Subaru fans are going to fit between the radiator and the engine. Violet/green is the signal wire that should go to pin 21 B134 on the ECU. It has four big wires, black yellow, red yellow, red, and blue red. Take the yellow and red/white wires at the compressor plug and splice them together. any updates? What you’re looking at here is a EZ30R Subaru engine (3.0L, 6 cylinder boxer) that normally comes in the Subaru Outback/Legacy 3.0R and Tribeca. We did it! So I cut a lot of that out. The radiator setup will be another tricky part. One good thing about this setup is that we could just unplug the compressor or compressor relay and turn the switch on to run the fans if it's running hot. Of course, we’re talking about 3-litre 6-cylinder Subaru engine manufactured between 1999 and 2009. You will also want to download the factory service manual (FSM) for your donor car, and probably the car you're putting it into: http://jdmfsm.info/Auto/Japan/Subaru/Legacy%20Outback/2002/. The money and time you'll save by not buying a complete donor car and removing the wiring will probably pay for the standalone. We'll send you back a custom plug and play harness that keeps the amenities of your car while adding … jdm subaru legacy ez30. Didn't wind up cutting or splicing any wires for the OBDII connector, but there are really only four pins on it that matter. From a daydream idea to reality. Pin 8 is pink/white and goes to the temp sensor. Pin 9 B136 of the EZ30 ECU is an orange/white wire that I ran to the input of the tach adapter. There is 12V going through the pressure switch and the thermal overload and then to the AC compressor relay. One is pin three of the gray connector for the main fan relays. or you could swap the dash harness and merge the body harness. I plugged the connector from the 99 that goes to the compressor into the H6 compressor. I think they were corroded together and/or the bellhousing dowels and torque converter pilot were tight. There are various green/black wires running around the harness that are 12V with ignition on, perfect for this. When we put this in the 99, I wired the black/white wire from that instrument panel (pin 8 i10, about the middle of the left hand connector) to the black/white wire coming from the 2002 alternator. The TCM needs to be grounded, so ground pins B9 and B19 (brown/white wires) of the TCM. Piece of 2" square tubing pictured in between I was using to check for clearance. I wired this to the output of the tach adapter. ... JDM Subaru Impreza 2004 RS 2.0L Replacement Long Block Swap EJ20 EJ203. The next easiest is probably to buy an engine from a junkyard and use a standalone ECU. If you're not going to have a Subaru automatic, you need to get around the inhibitor switch. For Subaru’s larger cars a little four-cylinder isn’t quite enough. I did eventually wire it to the 99 brake and clutch pedal switches so it turns off if you hit either of those pedals. By far the biggest headache is the wiring, especially since it means removing both dashboards and HVAC systems to get at it (and putting one of them back in eventually). There are a couple of EZ30 swaps there. Near the ECU I spliced those to the wires coming out of the 99 EJ25 ECU. I plan on getting it tuned sometime and I've heard they can keep some of those from coming up. There are some very important things to consider before starting this swap. This is a lot more resistance than the solenoids but seems to work. The main code we kept getting was the fuel level code, P0463 I think. Subaru H6 EZ30 conversion Post by Shaundon » 26 Jan 2016, 13:47 In a moment of madness i went and bought a Subaru legacy outback with a … I think the only reasonable solution is to put a pair of pusher fans on the front. I cut the wires that are grounded in various gears, at the TCM these are B22 light green/black, B17 red/blue, B23 blue, A1 blue/black, A10 yellow/blue, B18 red/green, and B8 green. "Subaru made it bolt right up, iWire makes it plug right in." so far ive found:-radiator needs to be moved forward under the crossmember, adding 2 cyl to the front of what you already had losses space. Connect that to the pink/white wire for the EZ30. Debated putting the 02 instrument cluster in the 99 but physically it's surprisingly different and electrically it will probably be simpler to keep the 99 instrument cluster. There are four ways to get a running H6 Subaru. Sign up for a new account in our community. So, again using the FSM, figured out the CEL/MIL, oil pressure idiot light, and temp sender (for gauge). So I cut it and so far cruise works and no codes. The stock radiator. Here's some clips of the exhaust note filmed before the partout. Even if they did, I don't know where the air would go when it came out. This is where the flat-six engine comes into play. Just FYI, it wouldn't be the 1st engine swap I've done I would definitely recommend doing a manual conversion in a six cylinder car rather than swapping one of these engines in a different car. This would definitely be less wiring to fit in the car than the way we did it, but you'd really have to know what you're doing and be confident you're not going back to the stock engine. Introducing the new custom head stud for the EZ30R and EZ36 6 cylinder engines. The other side of fuse 17 goes to the green blue wires, pin one and two of the other gray connector. So now the AC works. Main fan is driver's side, sub fan is passenger side. The brown/yellow wire disconnected will cause a P0447 evap emissions vent control circuit system open. Connect this to the green/orange wire for the EZ30. For engine or trans swapping purposes, the 2001-2004 non VDC cars are the simplest. The easiest is just to buy a decent H6 Subaru. Since you seem to be staying with the auto trans, that will make it simpler (relatively speaking). The picture below also shows the tach adapter. Also duct taped both sides of the flywheel shield, there were some slots in it. Oil pressure switch is green/orange, MIL/CEL is red/white, and temp is pink/white for the 2002 EZ30. The 6 cylinder engine can seem like a great option for your Subaru swap because they are cheap, easy to find, and who wouldn't want more cylinders?! There is quite a bit of wiring involved to keep the TCM, and therefore the ECU, happy. If I do flip my toggle switch to ground the neutral wire I do get a park/neutral code (P0851?). You'll send us the body wiring harnesses from your car and the car that matches the engine you plan to use. In Japan, the EZ30 was introduced in the equivalent Lancaster 6 wagon in May 2000. The yellow/green wire going to the compressor energizes the clutch, it's the only one really needed. For the most part, mechanically this swap is simple since it's Subaru into Subaru. Also put a resistor between temp gauge and ground to see the needle move. The other side of fuse 18 goes to three green black wires. If these aren't grounded I think it causes the OBDII port to not work. i have recently acquired a 2002 outback that was wrecked and i am intending to swap the h6 into my 2001 impreza. This post and the links above will help with the wiring side of that. It goes by many names, most commonly the Subaru H6, EZ30, EZ30D or EZ30R. The next posts will cover the plumbing and mechanical issues. Power steering lines at the top of the crossmember thread right in. The 99 has a four pin connector B72 for the ignition switch. These both seem to want voltage. This Toyota 86 rolled out of the factory with a 2.0 L 4U-GSE flat-four. Subaru EZ36 engine tuning EZ36 Turbo. It has stalled a couple of times, which I've read is a side effect of it thinking it's always in drive, but hasn't lately. its a ton of work you need about $3,000 to do either swap. Almost bolts up flush to the head, back end of the cats probably has to go upabout 1". I got a terminal strip from McMaster. I would recommend this, if you want a manual trans, swap one in, you'll probably need to swap the rear diff too, still less work and expense than an engine swap. At the top of the picture are the 10W resistors we wired to the TCM so it thinks it's still hooked up to solenoids. The 99 VSS has three wires, I believe they are red/black = 12V, green/black = signal, and black/red = ground. But we should mention that this 3.6 liter motor is more reliable than EZ30. It would be a little interesting to see. One of the last things I did before we pulled all the wiring out was to figure out the feeds for the various gauges and idiot lights. This seems to throw a fan code on the ECU if the coolant temp starts to get hot, I assume when the ECU sees the fan relay is already grounded when it tries to turn them on it gets confused.
