  1. Hi all, I'm looking at purchasing an '06 OBW that had a JDM 2.5 ej253 installed a couple months ago. The seller sent me a video of it idling.: There's a weird slightly rhythmic clicking/clacking noise that repeats every 1.5 - 2 seconds. It doesn't seem tied to the RPMs of the engine though. Any thoughts? I have to drive 4 hours to see/pick the car up. Hoping to feel more secure before making the 8-hour round trip. Greg
  2. So my 2005 ob xt 2.5 blew up and I wanna swap for a new jdm. Does anyone know what/if anything o need to switch over for the us. I know the intake manifold/ exhaust manifold/ and turbo all need to be switched but I was wondering if wiring is different or camshaft/ crank shaft are different?? Any help will be greatly appreciated!
  3. Greetings all, Im replacing my DOHC 2.5 engine for an SOHC 2.0 JDM... Is anyone familiar with that type of swap?? Do you know what kind of issues i would be encountering?? So far i was so lucky as to take out my old DOHC engine. Realized i couldn't use my intake manifold (duh). So I'm curious as to know anyones pros and cons to my upcoming project.
  4. Hey all. I keep finding JDM EJ22 motors on Ebay out of Legacy LSi's with about 40k on the clock. I'm wondering if there are marked differences between USDM and JDM blocks that would make parts hard to find? Thinking this could be a great candidate motor for a swap. http://www.ebay.com/itm/94-98-SUBARU-LEGACY-2-2L-ENGINE-JDM-EJ22-LEGACY-LSi-Engine-EJ22-Automatic-4wd-/371159568581?pt=Motors_Car_Truck_Parts_Accessories&hash=item566ad590c5&vxp=mtr Years available generally look to be from 94-98. Thanks! W
  5. Hi all, I have owned a Subaru for a long time (87 wagon with a 4" lift) not to familiar with the newer Subaru's. I recently picked up a 00 Outback wagon from a guy that was trying to swap a 04 ej205 JDM WRX motor into it. It would be a sweet ride but the problem he ran into is the 04 USDM WRX harness won't plug into the JDM motor. So my question is, has anyone had success with this type of swap before? My thought was to install a US WRX intake manifold along with the cam pulleys, crank pulley, and all the necessary sensors to match up with the US WRX ecu and wiring. Any thoughts or ideas are appreciated! Thanks 00 Outback Wagon 04 WRX ej205 JDM motor 04 USDM WRX complete wiring harness + ecu 5 speed AWD
  6. Ok. so I have started back on my RX project again. been really busy with moving and such, she kinda got put on hold. Picked up my new JDM motor and tranny and have slowly been tearing it down to do a re-seal and tighten things up before I drop it in. Pics of my 5-lug swap... Using front end parts from a 99 OBS rear is all XT6. And here is what I have been doing more recently. Not sure if anyone remembers me contemplating dropping a EJ20t into her but atlas I decided not to "settle" for what I didn't really want... SO yeh. here's my new Version 4 JDM EJ20 Sti and tranny... Motor came pretty well complete and I got a smoking deal on it! included the TMIC,harness ecu, turbo timer, and Syms racing Downpipe and header! Now, I could have dropped this motor in and head it running by now but I convinced myself to tear it down and do a complete re-seal of the entire thing. And since im doing that I might as well to the head gaskets and port the heads and intake while im in there. also ordered up a set of ARP head studs. Also powder coating a few things while I have it apart. I'm going to be powder coating everything I can on this guy to keep it looking clean for years to come. ill post more pics of stuff like that as they happen. lots of cleaning left to do, still need to port the heads and intake, waiting for gaskets to arrive (hopefully tomorrow). I've also been getting goodies for this project as funds allow. see such goodies below . B&M Turbo oil cooler. New TMIC next to the JDM IC that came with the motor. Figured I had room for a larger one so.. Why not! New silicone turbo inlet tube and New TMIC Y pipe. Stage 3 6-puck ceramic clutch and 12lb flywheel. should give me nice fast revs! also considering going with a lightened under drive pulley kit. New GFB response BOV. fully adjustable atmo/resirc! So, that's my progress thus far. As I said as funds allow I will be doing more work to it. should be running before to much longer and I will keep everyone posted as things happen.
  7. Recently purchase a JDM EJ25D on ebay. I've made the necessary intake manifold swap, and have also discovered that there are differences in the water pump, timing covers, and A/C mounting bracket. Only one thing (right now) is holding up putting the motor back into the car. The EGR pip rises from rear of the head on the drivers side up to the EGR valve on the intake manifold. The JDM has the port, and it is tapped with the same thread as the USDM head, but the bottom of the hole is different. Here is an image of the JDM port: And here is the same port on the USDM head: As you can see, the bottom of the port on the JDM head has a tiny hole in the center, while on the USDM head, the port is wide open. I don't know whether this difference is due to the market, or the model year, but I would like to know if I can open up the bottom of the port on the JDM engine. If so, how should it be done? I have the exhaust removed from the engine right now, so i can look up through the exhaust port and see that pinhole. Would it be better to drill it out, or try tapping it out with a punch? Any help will be much appreciated! Thanks in advance.
  8. Anyone know off hand if a JDM Ver 3 GC8 STI transmission will fit up to a EZ30r? Form my research, it should, as anything EJ will hook up to anything EZ. But the JDM is worrying, as I have no experience there. Any help would be greatly appreciated.
