  1. I have a noise coming from the middle right side of my car that sounds like a bearing going out and grinding/etc. There's also a metallic rattle. Here's the strange part: I've replaced the rear differential with a another diff I know wasn't making any noise, noise still there but slightly better. I replaced the center diff (including transfer gears) on my 5MT with parts out of a low mileage transmission that I knew was quiet, noise still there but much better (previously unbearable). Thinking that I narrowed it down to the driveshaft carrier bearing: I swapped the drive shaft with another low mileage donor, noise still there. The car has 3 brand new wheel bearings, and the fourth came off of a low mileage car and is up front on the passenger side. The sound isn't coming from there... I think. It's almost as if the noise originates right behind the passenger seat. I have triple checked that the exhaust and driveshaft aren't making any contact. Strangest mechanical issue I have ever dealt with on a Subaru. Next step will be replacing the transmission as a whole, but I'm trying to think what else it could be before I commit to that.
  2. Hi Bolts, That ECU is for a Non-Turbo engine. What you are looking for is a Denso 22611AK221. They show up on eBay every once and a while. the '04 models ('05 USDM equivalent) used the same ECU for the sedan and the wagon with the 5-speed trans.
  3. The picture will be upside down, sorry. The pre face lift JDM legacy did not have TGV's.
  4. Interesting! You made fantastic progress with your swap. I can't wait to see more. I've been slowly working on this for months. I acquired a JDM 2004 LGT Spec.B EJ20Y with 4.44 trans a while back. I've done a tear down of the engine to make sure everything was well before it was swapped in. I've have the JDM ECU from the donor car that this engine came out of. (22611AK221) I've got a good chunk of the wiring diagrams from the Factory Service Manual Printed out (see below) from both the '04 RHD Turbo Legacy, and the '05 LHD Turbo Legacy. I've been comparing them with scrutiny to make sure I don't screw up the brand new LGT bulkhead I bought from Subaru. I found that a set of unused pins on the USDM ECU are used by the JDM ECU for exhaust AVCS. Interestingly enough, the Pins mapped to the TGVs on the USDM are unused on the JDM ECU. I will be making a piggy back harness for both the sensors and the solenoids. I am using two different sets of Four Pin Subaru connectors so that the wiring looks pretty much factory. I also was curious about how you did your ECU pins. After an evening of searching, I was unable to find anyone that carried the female pins for the LGT ECU. The solution I found: Find the manufacturer of the ECU connector itself. Additionally, I bought a complete immobilizer system (including a 22611AJ17B ECU) from a USDM car, and swapped over the immobilizer chip itself. (It has been confirmed somewhere on this forum that the JDM immobilizer can be reprogrammed by a US dealer, but I want to be able to start the car when it's done.)

(Some of them may be upside down, sorry in advance.)
  5. Assuming the '03 Spec.B you bought is a fourth gen: (And also a manual trans) You're gonna be looking at an EJ20Y in that car. The EJ20X/Y (X was the automatic trans variant, Y was manual). This is a pretty run of the mill EJ20 with a couple extra things tacked onto it. First: This is a Dual AVCS (Active Valve Control System) engine. Which means all four of the engines camshafts are capable of variable timing on the fly. The DOHC motors have had single AVCS for a long time, and dual wasn't introduced onto the Imprezas until the 2008 model year. (Version 10 EJ207/EJ257). The heads on this motor are going to be stamped 'Z20', they flow pretty good for stock heads. The EJ20X/Y has a static compression ratio of 9.5:1, pretty high for an open deck turbo Subaru engine. Keep the compression in mind if you plan on doing any turbo upgrades or engine modifications. Second: This motor will have a factory 12mm Oil pump which is capable of pretty high oil pressure (is known to spike way over 100 psi when cold starting the car). This oil pump was chosen specifically for this engine because it needed the higher pressure. This also means that the stock engine (At least on the manual trans) is capable of higher RPM than most other stock EJ20s. Third: If the Spec.B you bought is a manual trans, it will come with the JDM first revision Spec.B 5-Speed. This trans uses the same gear ratios as the 2.0GT/2.5GT. However, its final drive is 4.44 vs 4.11 on the non Spec.B trans. The model of trans you should have is TY757VBABB. This trans won't have the dual cone first gear synchronizer found on the post revision Spec.B 5-Speed. There are also minor differences in the snout size on the pre/post revision 5-Speeds. Note: This also means you will have a 4.44 R160 VLSD rear differential. Fourth: If the car you bought is manual, it will have a twin scroll TD-04HLA turbocharger. If Automatic, it will have a twin scroll VF-38 turbocharger. Both of these spool pretty low which is nice, but lack in high end power. Both of these turbo have the same up pipe flange and down pipe flange. However, this up pipe/down pipe flange combo is not found on any other Subaru. The only off the shelf downpipes you will be able to find (also called metal catalyzer) might be very pricey. (I live in the US, so I may not have the same availability as you). Header/up pipe combos are likely the same deal. Yes! Anything after the down pipe is the same setup as the USDM car. (not sure about the EDM spec). Just be aware, this car has equal length headers, and you won't be getting any noticeable rumble. Hopefully you find some of this information helpful!
  6. Minor differences in the TY757Vxxxx transmissions are usually gear ratios, differential ratios (also known as final drive ratio), and Synchronizer rings. I can attest to the TY757VBCAB being a pretty bad transmission. (mine started making noises at 150k miles). I currently have a TY757VBABB out of a JDM '04 2.0gt Spec.B in my '05 2.5i. Wonderful transmission, and I got it for really, really, cheap. The catch is I had to replace the rear differential (in this case a 4.44 VLSD off of an '04 Forester XT). I have also *had* a TY757BBAB out of a JDM '05 2.0gt which was making bearing noises (Or so I thougt... truthfully I think it was low on fluid). When I swapped this trans in to my 2.5i, I also replaced the rear diff with a 4.11 VLSD. The transmissions will bolt right up as expected, but I do have some notes specific to the TY757Vxxxx's that you may find helpful. 1. The Turbo cars and the N/A cars use different Reverse/Neutral Sensor harnesses, in order to make the swap work, you will need to pull the harness off of your original trans and out it onto the new one. (Sensors are the same though) 2. Make absolutely sure that both sensors have a washer on them when inserting them. Without a washer the neutral sensor makes contact with the shift rail internally causing the gear shift to bind. In my case the gear shifter was very hard to move, and I could only get the car into 1st,3rd, and 5th gear and even then it did not feel like it was actually in gear. 3. Replace the axle seals on the transmission before you put it into the car. 4. The dipsticks between the turbo trans and the N/A trans are different. Either will work on the N/A. 5. When shopping for clutches, note that the clutch fork in the turbo trans may be different than the throw out bearing coming with a clutch kit is designed for. The Clutch fork the on TY757VCACA is thin and narrow, and the TOB won't fit on the Turbo trans fork. This may take some guessing, but as far as I can tell the TY757VBBAB had a newer style thicker/wider fork and the TY757VBABB had a smaller thinner fork. The TY757VCACA's TOB almost looks like it would fit on the TY757CBABB's fork, but it doesn't. 6. The 05-09 Legacy's do not have speed sensors on the trans. 7. Drain the trans fluid before you drop the trans, and don't fill it until it's back in the car. (It will spill out when full, and either the driveshaft or axles aren't inserted.) Hope this helps!
