Need question answered for doing 1993 Ej22t swap into 1998 impreza
Ok as the title says im doing an Ej22T from a 1993 Legacy turbo automatic. into my 1998 Impreza L wagon Automatic.
a few questions for those that might have info 1. Is there any write-ups. i did a quick search and didnt get anything 2. Is there any way i get get the specs of this said motor. like Compression ratio and stuff 3. how much of a pain is it going to be to get this old 1993 motor to pass OBD-II emissions 4. any useful sites to get performance parts for the motor from 5. any useful sites to get rebuild parts from. (head bolts, head gaskets, ect..) 6. anything you feel i should know

It will not pass OBD2. No easy way around that.

^^yep 2.2t leggys were before obd2...so either get a 95 or older body(or change some things to make the car seem older...if you get what I'm saying)no other ecu that will run the 22t is obd2.

Im running an EJ22T hybrid with a merged harness in a '97 Outback, but it still uses the Legacy turbo ECU which is OBD1, so no emissions passing for me.

But the whole OBD-II thing also varies from state to state. Up until a couple of years ago, they would fail you here if you had a CEL. It didn't matter what it was for. Then they went to plug in OBD-II testing and only fail you if the CEL is related to emissions equipment (which includes the 0420 CEL that's so common). But here's the kick in the pants. If they plug you in and it doesn't veiw OBD-II readiness they just mark that down saying the computers couldn't talk, and put you on the dyno and tailpipe test you. What this means is that people with standalone ECUs that are not OBD-II compliant can now get through emissions as long as your tune is clean at the pipe. It makes no sense, but those of us messing around with our cars who have the conciousness to keep the car running clean and efficient don't have too much to worry about. The standards got tighter a couple of years ago, but as long as you run a high quality cat and not some $50 Catco cat from Jegs you're good to go. |

what if you ran dual ecu's? run only the wiring needed to makw it work, and leave the wiring for the stock ecu to handle everything else.
this is either a good idea, or won't work at all |

Sure you could do it and it'll run. But it will not achieve OBD2 readiness. The tests that need to run to set the monitors to ready will fail because the expected results will not occur.

I know many folks in Houston that have tried to trick the OBD-II test, but have been unsuccessful. I'm running Link G3 Plus and Link G4 EM on both my cars, neither of which would pass an OBD-II test. My tuner and I have discussed this topic many times and when / if my area goes non-attainment, I'll have two cars that are suited for "off-road" use only. |

I get the impression that some of the people in this thread don't really understand what OBD-II is. It's not some module or a physical thing. It's a testing protocol. It's a standardized ability of the emissions computer to talk to the car's ECU and withdraw or track the functionality of the key sensors and systems related to the car's operation.
The reason the above mentioned 2 ECU approach is ludicrous is because for a car to have a working fucntioning OBD-II protocol it's going to need to have the newer OBD-II compliant ECU still wired to EVERY single sensor on the engine and in the engine bay. You know when you take your OBD-I ECU and plug the plugs together to pull the codes or run the car through the readiness tests? This is what is done in a different way on an OBD-II compliant car. This is done through a single port/plug that a computer can plug into. It's the same port you use for a Cobb reflash or for OS tuning on a newer USDM WRX. If you are subject to OBD-II testing in your area, what they do is plug in the car to their OBD-II computer and they pull your codes. They run the car through the readiness test. If they can't do this and their computer can't talk to your computer, in most jurisdictions you fail. They say you aren't OBD-II compliant and expect you to go fix it. In many states there's a limit to how much you are required to spend in your attempt to fix it. It's generally $500 or so. Then they will give you an exemption pass if the car tests clean at the pipe. In many states that's a 1 time pass. In others it's an exemption you have to get every year and have to provide receipts (new receipts) every single year of your ongoing attempts to "fix" it. There are ways around it. Most of the ways are both state and federal crimes with potential fines up to $10k. I'm not saying you can't find a way around it. But it's not something I would really encourage you to pursue. |

my forester e-check last year:
i reset my ECU with my snap on scanner just before going to the testing station last time. it was tossing CEL from a slow O2 sensor and i just needed to pass. well it showed readiness/communication with all sensors but no history of codes(just erased duh!). they had to curb idle test it since the code history wasn't there. even tho it passed OBD-II communications test 100%, i still had to get sniffed. is this normal in other states? it probably didn't help i still had the scanner on the passenger seat when i went thru! the tester looked at it and shook his head. then i got the 19ish girl inside telling me it's not going to pass because it's been reset! i laughed and said if i had got it fixed at a dealer, they would have reset it for me and sent me on my way to the e-check station the same as if i had done it my self! she looked pissed and said, "well, your car passed... barely." but next time you can't do it yourself! i laughed and repeated that to her manager(who did the test and shook his head) who happens to be a friend of my dad and the garage we own. he didn't look happy as he reamed her out(she was staring @ the floor while he was getting red in the face), now her car isn't there anymore! lol darn... just some happy emissions experiences.... so even tho plug in is for OBD-II they still have the ability to put you thru more stringent tests like OBD-! sniffers, etc. --keith |
