I just reread your first post, I missed a pertinent question. Is the car manual or auto?

You'll be looking for a 93-97 (maybe 98) impreza. These are the only cars in North America that came equipped with the ej18, 93 and 94 are strictly ej18 cars, 95-97/98 were a mix of ej18 and ej22 but it won't be hard to spot the difference.

That iacv doesn't function the same electronically. It won't work with a phase 1 ecu, I had that thought several years ago. I actually think I suggested trying it in Chux's thread about the car he was talking about above. Either way, I tried it for myself on one of the cars I've done this type of swap in and no dice.

Cats and o2 sensors are the same as what is on your car already. unless they are bad there will be no problems.

I've used impreza exhausts on legacys several times, both aftermarket and stock replacement stuff. It's really not that difficult, nor expensive.

ej18e throttle body is the missing link. It has an integrated iacv that functions exactly like the rest of the phase 1 divorced iacvs. You'll need the tps plug from the impreza harness because it's connector is different, you'll have to simply repin that. You'll also need a sheet of metal to make a small block off plate to bolt in between the throttle body and manifold, this will cover the ej251 iacv port in the manifold.

The 1st gens also have a decently heavy automatic seat belt system and large steel crash bars, whereas the 2nd gen has manual belts and composite crash bars with skinny steel reinforcement.

I have a bad mainshaft bearing ej 5mt up here I'll donate the stubs from if you're interested in doing it.

Is the gl a 5mt? If so you can swap the stub axles to 25 spline stubs. Requires disassembling the transmission, but it's not a difficult job.

Driver's side hanger on the muffler is too long, it'll have to be cut it'll live in the tow hook. The hanger on the midpipe may fit correctly if you extend the piping before it, otherwise it'll be off by a good bit. Strategic placement of the extension(s) will make it work though.

Not without modification, the impreza exhaust is roughly 5" shorter than the legacy. A could of the hangers are also in different places.

From my experience, and a few others on the forum, legacy/impreza axles are a bit too long to work in the ea82/xt6 platform without extending the control arm roughly an inch.

The rear subframe is essentially the same, minus the mount for the front of the rear diff. The swing arms are what the sway bar mounts to. Make sure to use 4wd rear struts with the 4wd swing arms unless you want a 2" lift.

Advance auto lists ea82 and ea82t axles as fitting ea81 cars as well. Neither type will fit lol, you've just gotta be smarter than the person at the counter.

Your ea82 na is 23 spline, only the ea82t transmission have 25 spline stubs.

If it helps, my old 99 legacy gt has been running an 02 impreza RS 4eat for 2 years.

The code may be different, but they are electronically compatible. And it looks like the final drive ratio is the same. There should be no problems swapping these.

I've done several difficult and different swaps in my days. But I think I'd rather throw myself in front of a moving car that attempt what you're thinking of doing. The complete wiring harness from the 00 will have to go into the 04. Every. Last. Bit. And that's just the beginning. Many of the body side connections are different; lights, door harnesses, dash harness, the 04 has dbw where the 00 is cable. I could continue but I'll stop there.

Yes, you need the 24 spline, the 21 spline is a 2wd clutch.

The 08+ impreza suspension as a whole is different, but there have been people who have used them on ea chassis. Huck's original frankenwedge is currently running 08 wrx coilovers in NC.

I'd venture to say if the front needed lift spacers to level it out that it has 2wd rear struts installed. My old xt had 2wd rears on it for a while and it had a massive rake until I got the right struts under the back. You can get 4wd kyb rear struts pretty reasonable from rock auto. As for handling the situation with ground control, the closest match suspension wise to the ea82/XT platform is the 00-04 legacy or 08+ impreza . There have who have used 08+ impreza coilovers before, though posts about fitting them are few and far between.

96 ej22 cars can have either type evap system, it depends on the build date of the car. The ej25 cars are the same way in the 97 models, very late built cars have rear evap where earlier ones have it up front.

Cable clutch legacy/impreza fork will work too.

Remans in general such because they're using substandard parts and minimal quality control.
