EJ20X into a 2004 Baja Turbo
Any more info from this swap. Particularly the tuning bits. My ej255 is about dead and need a reasonable solution soon. It seems this is that solution. The problem is that I need to get the engine in and running the same day, since I’ll be doing it at a friends garage in which it can’t stay at. So I need to get all my ducks in a row.
EDIT!!!! 06/18/19 It is confirmed! Running the factory timing setup and disconnecting exhaust cam timing and sensors works fine. Anyone doing this swap, in the future, should save yourself the hassle of changing the timing on the exhaust cams.

I'm using/have used the openport 2 from tactrix, combined with rom raider and ecu flash.
It's worked really well for me, and I've learned a lot along the way. For my application this setup ran and drove ok ish without changes to the tune, but I wouldn't recommend it for long. I babied it around town for a few days while I roughed in the fuelling and made sure I wasn't seeing any crazy lean spots or knock. I have a spreadsheet of what I spent on what. I'll try to get that uploaded tomorrow. Also, good advice. Before you put the "new" motor in, remove the screens from the oil feeds to the turbo and avcs. Or at least check them. Mine ended up being at least partially clogged. Which resulted in Avcs check engine lights, and a wiped out turbo. I also ran other teething issues with old O2 sensors failing, but I think I'm past that now. |

Gotcha. I already have a FXT Ecu and Cobb’s AP. My tgv’s already failed so I have tunes for the delete. I wonder how far it would be off with a Cobb stage 2 OTS tune? I plan on using my stock exhaust manifold and turbo.

Read this thread and there is some good info. Thanks. I am looking at this swap in a 2005 Baja turbo as well.
So just so I am clear here: -Get an EJ20X, swap the 255 intake manifold, exhaust, turbo and TMIC over from the 255? -Only hook up the top AVCS of the 20X as im assume the 255 is a single cam AVCS where as the 20X is a dual cam AVCS? -No need to run a different ECU, the 255 ECU will work fine? And if thats the case, would I be able to run a Cobb AP like Zodak said? I have a 207 swapped 92x but it was a breeze bc it was old engine/ecu out, new engine/ecu in, run 4 wires to ECU/AVCS...boom done. No swapping turbos and this that and the other over.

Also, the timing belt for the 255 and 20x should be the same but what about the valve covers? Ej205 or 255? Are they the same?

Timing belts are the same, valve covers are not.
While it will run "as is" with the ej255 ecu on the 20x there is a lot to be gained by tuning it. Having the wideband AFR gauge and logging it through the tactrix openport 2 made getting the fuelling right much easier. In my case I also needed to mess with the cranking fuelling to get it to start at temps below 30 ish. It's negative 10 here right now, and it starts ok ish, so I'm not too far off there. But that need will vary with your climate. |

Sorry, it's early, I just re-read your earlier post, and I think what you do depends on what your end goal is.
If you have done the the 207 into the 92-x I think this could be done in much the same way, having working exhaust Avcs would be cool (you would need to run wires, some people repurpose the unused tgv wires to do this), and not having to tune would be cool too. That being said I don't know which ECUs would like this motor aside from the JDM unit. Which I've read don't play nice with the Cobb access port or tactrix, so if you want to make power or retune you are out of luck. Also heard the JDM ecu will not talk to US emissions test stuff, which can be an issue for some people, depending on local enforcement. |

Well I don’t want to change the intake manifold. I just need it to run for now. I can worry about the other stuff in the summer.
So: Swap exhaust manifold Swap engine harness Swap sensors? Which ones? What else? |

The coolant temp sensor will need swapped, jdm one has a different plug, the knock sensor may be different? If the plug is the same then it's fine. The map sensor will need to come off the US throttle body and get moved to the JDM intake.
The US turbo compressor exits different from the jdm one, and I'm not sure about mating the US turbo and intercooler to the JDM intake, but it might be fine? Also keep an eye out for the fuel pressure regulator. The JDM motor I believe had it mounted outside the engine zone, mind didn't come with it. I had it yank the FPR from under the intake of the US motor and relocate it. I'm sure I'm forgetting something, hit me up you go and I'll share as much as I can. |

Also, in some cases for hoses and brackets and stuff I've found the 08-14 wrx uses similar if not the same items as the ej20x. So my intercooler bracket (but not quite the intercooler itself) was the same.
Also, the PS pump. I think I said it above (like way earlier) but I had to find a union and cut the hard line and use the JDM/08-14 wrx pump. The ej255 pump bolts up but doesn't clear the ej20x intake. In summary: Depending on which things you do different stuff might need to be done. But ya, keep asking questions and I'll do my best to answer. If you want a pic of a particular thing I did let me know, it's a short trip to the garage. |

Yeah man. That’s awesome. What did you have to change in the programming/mapping. I’m just curious.

I have done a similar swap, but have not been able to get rid of the CPS malfunction code. I swapped: EJ205 JDM longblock into 06" Baja turbo. I used all of the USDM intake/sensors/wiring/ECM. USDM Camshaft position sensors are 3 wire Hall effect to work with USDM camshafts that have grooves for timing indication. where the JDM sensors are 2 wire magnetic sensors and JDM camshafts have humps for timing indicatation. I swapped in the USDM camshafts to match the USDM sensors. I modified the right side sensor to line up with the groove in the camshaft and it worked. The left side I had the grooves in the camshaft lengthened by a machine shop to line up with the sensor on the left side........It is still giving me CPS sensor error code on the left side. I just ordered another new sensor to try to fix this, but I am not confident it will work............When I turn off the CPS codes in the tune the engine will not start or run. Another post suggested you can put a USDM CPS sensor in the spot behind the pulley the same as the JDM setup and unplug the rear sensor/plug it into the front and it will work. Really I just want the car to run without codes so I can sell it......Anyone have any Ideas??

Is there an engine that would be a more likely replacement candidate that the ej20x? Other than the ej255 of course. I’m looking for something more reliable than the ej255 and it’s inherent ringland failures. Which is what’s wrong with mine now.

i just have the long block, it looks to have come out of an automatic, but i didnt get a wiring harness or ecu with it. at the moment, it probably has the intake manifold from my baja bolted onto it. I do have a forester xt ecu that i was going to put into the baja, though, but it is also from an auto.

I think I want to get an engine/trans combo. Seen this on eBay.
https://www.ebay.com/itm/04-06-SUBAR...53.m1438.l2649 I wonder if the Spec B 5-speed JDM trans is stronger than the crap one in my Baja. 1st-3rd gears are definitely longer which is cool. Should be stronger, but definitely slower, but that's ok, just make more power. LOL! https://drive.google.com/open?id=11h...T-L2VGtH8cbKsJ Last edited by Zadok; 02-08-2019 at 01:37 AM. |

How is it? More so, how’s the trans. I’m on my second and soon third Baja 5mt. They are junk. And I’m not hard on it.

i didnt get the engine into the car, if you just drop it in as is, you will have issues from the exhaust cams being adjustable with nothing controlling them, i think they default to a position that is safe but kills power. also the turbo isnt the same outlet as the other twin scrolls, so finding down pipe for it was a lot of work and even then, i wasnt able to find one, only a raw flange. I ended up changing the plan for my baja, thus why i have an the engine available now. from what i have heard, you can put a standard cam gear and exhaust cam in it and it should run fine, mightneed to delete the exhaust avcs solenoid, though. it was more than i wanted to deal with, though. I am hoping to save up some money and get a wrecked 3.6L outback and swap everything over, that way i can keep as much stock as i can, i want the baja to be a reliable adventure rig when i get done.
I cant comment on the 5spd, my baja was a slushomatic with 265k on the odo. |

Thanks! I ended up changing a bunch of stuff, maf scaling, intake Avcs settings, lots of things. I have an aem wide band that logs through my tactrix openport 2, so I've been using that to get the fueling right. I'm not super experienced with Subaru tuning, so I'm taking little steps and refining as I have time.

EJ20X is the easiest route outside of an EJ255.
They're also a forged crown, cast skirt piston, so should be pretty tough. The higher CR (9.5:1 IIRC) however will probably like E85. |

That’s good. I have E85 at the pump 3 mins from my house for under $2 a gal.
I’m going to throw in the 20x and get a header, uppipe, maybe even a turbo if I can swing it. Then pay this Cobb pro tuner I know to make it right. The exhaust cam position is the only thing that scares me. I can certainly advance or retard it a tooth if that will fix it, but I have no idea how to actually figure that out. |
