CRAPOLA! I've got the three wire coil.

Wouldn't it make more sense to rewire that ignitor and three wires into the new four wire style? I've got the engine harness off the 2.5. Can I frankensplice?

I'm still wondering if I'm going to be able to accomplish this. Gimmee a hand fellas! I appreciate everything I've learned so far. A little more figuring, and I'll dive in.

I had a harness and a new style Coil, I thought about trying to make it work but it would be really involved. INstead I just had plug wires made and overnighted for $50. much more time and cost effective for me.

If you want to go the custom plug wire route. I got mine from Kingsborne wire werks. http://www.kingsborne.com/800.htm.

Someone just did a this swap and when he called them explaining what he needed they said they still had my order on file and the part number was "16-SVI". They are just long enough to fit in the stock location of the coil. You can also specify wire thickness, color, and they can print script on the wires if you choose.

Hmmm... I know you read both mine and moose's posts, all i can think is make the throttle body blockoff plate ahead of time and the plate to mount the old ignition coil if thats what you go with. This will save time. all I can think to wire is the injectors and the new style temp sensor but you can't do that until then engine is out.

Did you verify which Crank sensor trigger ring is on the 2.5?

Good luck, Let me know if you need any help, I have some wiring diagrams and stuff I can e-mail you if needed.

Do you have any pics of the engine thats going to be going in? Ide like to see exactly whats on it and how its equipped, maybe it will remind of something you might need to do.

I'd like to use the 2.5 coil. I've got a local shop that can make custom wires. In fact, they might do the install. I'm not sure how much help I'm going to have on it. So if I use the 1.8 coil I need that plate, right? The 2.5 I'd need to really get into wiring. Correct?

As far as the blockoff plate goes, do I need it? I think I'm going to have the throttle body off the 2.5. The car I'm getting it out of is getting an STi motor. I assume they got an TB with the STi motor. Will find out soon.

Aside from that, all I need to do is wire the injectors differently, eh? Can it really be this simple?

Oh yeah, how can I verify which Crank sensor trigger ring is on the 2.5?

If you really want to use the 2.5 coil than you might as well rewire the whole thing and use the 2.5 ECU. I could fnd no easy way to do it.

Throttle body, once again, if you plan on using the 1.8 ECU you would want to use the 1.8 throttle body do to the electronics. This includes the TPS and the IAC. The bore diameter on the backside is the same between the 1.8 and 2.5, so it really isnt like you will be gaining much by using a 2.5.

fuel injectors involve splicing on the new style connectors. Simply soldering 8 wires. then 3 more for the new style temp sensor.

Gotcha. All I need to know then is how I can verify which crank sensor trigger ring is on the 2.5. I'm lost there.

Truth be told, I'm fairly lost everywhere here. Hey, how hard could this be?

Nah you seem to have a pretty good idea of what you are doing.

crank trigger. If the 2.5 engine is out of the car already, pull off the crank pulley and timing covers. The crank sprocket that drives teh timing belt has a toothed ring on teh backside, it will either have 6 teeth (thats the one you want) or a lot more than 6 teeth arranged in a weird pattern.

If it already has teh 6 tooth ring you are good to go. If not then you have to either get a 6 tooth one, or wait till you pull the 1.8 and take the crank sprocket/trigger ring off of that and use it.

...you want 6 teeth

I don't understnad why I should care about that crank trigger whatchamacallit. If it's under the timing covers, who cares? What's it need to be compatible with? What's it do anyhow?

Also, I was thinking before I start I may want to do a valve job, with the engine outta the car. Good idea with 83K miles on the car?

What seals will I be needing?

Engine and tranny are sitting in my garage now on the hoist. Methinks tuesday will be start day now. Keep feeding me. I've never pulled an engine before. Pulled a truck apart around an engine once (replaced cab). Rebuilt a few top ends. But never messed with something like this. I know I'm smart enough to match parts up, but just need to know anything I don't know, you know?

Thanks again kids. This is going to be cool when I finally get to it.

I'm not sure about the valve job...but the timing belt and oil seals would be a good call with 83k. I'm doing the waterpump and thermostat too and I got everything from subaruparts.com for @ $200. This way I won't need to worry for 90,000 more miles. They have 2-day shipping for like $10 more.

If you have a hoist and a leveler pulling the engine is easy. Label any wires or vac lines and disconnect only what you need to free the engine.

Give us some progress reports.

youde want to be concerned with the crank trigger ring because if you run it off a 1.8 ECU, the ECU is thinking its a 6 tooth ring. Thats how it judges it timing and all that. If it is from a later manual trans car they had a different ECU than the Autos and also a ring with many more teeth. The 1.8 ECU will not run the engine if the 6 tooth ring is not on it.

Advice- have ALL your parts laid out in order and ready to go in. this was you'll know if you are missing anything. take LOTS of pictures before and as you take the car apart and label everythign you disconnect such as vacuum lines fuel lines wires etc. Label and photograph so you know how to make it work on the new engine. good luck!

I've been piddling with taking off some stuff here and there. I am about to really hit it in the next couple days. How long you think it will take to get it out?

Also, where is the ECU unit located? I figured under the passanger side dash, but it's not jumping out at me. I haven't dug in much though.

Thanks for all the help. I ordered the plugs from that place. They assured me they knew exactly what I was doing and what I needed. Only $40 plus shipping of $8. Woo hoo!

ECU is located in the passenget side footwell/floorboard.

Pull back the carpet (need to remove some plastic fasteners)

undo the bolts/nut holding the metal cover on.

undo the nuts holding the ECU down, remove plugs. thats it.

If you have the proper tools and equipment such as an engine hoist, you should be able to pull the motor in a day easy. Just document everything so you know how to put it back. It could take alittle longer if youve never done it before, sometimes it can be tough seperating the engine from the trans (spray some penetrating oil on the locating dowls and let it soak overnight).

also ide recommend having the blockoff plate already made and ready to go as well and new throttle body gaskets (both 2.5 and 1.8). that was down time is less.

good luck!

Bumping this back up since I wanna know how the swap went. Also, my 1.8 just went down, forcing me to get cracking on the 2.5 in my basement. I also plan on running it off my 96 1.8 ECU and sensors. until I can slowly develop the rest of the stuff I've been planning for it.

So how did it work out? Any tips for someone who is about to dig in?

Thanks,

I'm finally getting around to cleaning out the garage, and getting on this. Today I checked computers. Not plug and play.

So it looks as though I'll have to stick to the 1.8 ECU. I still don't quit understand the cam trigger ring thingee. 'Splain, please.

Reread what you said 100 times, and finally it clicked. I dunno what too me so long, that's simple. Perhaps I have a mental block about this project. I am installing new lighting in the garage this week, in prep for it. Sometimes I annoy me. Oh well, 6 fixtures with 4 bulbs each for the side I'm working on should make for some good pics. I'm fairly certain I have ADD, so I'll need to come inside and do some posting and what not anyhow.

MMMMmmmmm 24 bulbs. I can't wait to light up my garage.

Alrighty, I'm ready to start now. Hey, USGP is coming up next weekend, and we've got a huge group of Subarus showing up, I set up the event, and don't have mine done. An object will stay at rest....

Anyhow, really, the car is in the garage, I'm labeling and pulling things already, and hope to have the new engine at least in on Sunday.

I've thought, and thought, are rethought this many, many times, over and over...should I continue? I'm sure I'll run into some snags along the way. Would any of you be willing to lend a hang via phone if and when I might need ya? As incompetent as I am, I won't expect you to drop everything and talk me through a 45 minute procedure. Just a quick "yeah, you do this" to keep me on the right track here and there. And I DO NOT mind at all if you are busy and can't talk for even a minute when I call. It would just be cool to have someone who's been there, done that to give a pointer if I need it.

With that, any volunteers? Free beers for you, if you make it to the USGP next weekend.

Oh, yeah, Hawk, I think I understand the crank trigger ring now. Simple, really...now that my brain is on. We'll find out shortly.

HOLT CRAP! Less than 5 hours total time, and the engine is ready to be pulled. I'll be getting a hoist tomorrow. This thing was AWSOME to work on. Easiest thing I've done.

Now, can I drop the new one in as easy? Everything looks like it matches up almost exact. A few questions though.

1) The old tranny is 5 bolts. The 2.5 is 7 bolts. If I remember coorectly, you just don't use the other two spaces when you go to the 2.5. Is this right?

2) Throttle bodies aren't quite the same. What to do? Is there much or any difference between the two, besides design? They appear to be the same size. I may just use the 1.8's, as I think the bolt pattern is the same. Is it? OR, I'd have to swap whatever those two electrical connectors are onto the new one. Hey, what are those anyhow?

Can you tell I've never done this? Who cares? It's like legos. I've labeled everything, and even thrown a few things on the new engine. So far, so good. As I said, almost EVERYTHING matches up, 100%

Any advice would be appreciated, as I continue through this. I'll post a full write up when it's 100% complete. Soon? I think it will be. If I knew it was this easy, I would have started months ago.

Yama-

About 4.5 hours and the old one was free. Just didn't have a hoist until right now.

On that note, I just hooked it up for the first time. Any advice on the best way to do it. It's dark, and I'm buy myself, so I didn't jack with it too much. However, it appears that I just need to lift it high enough to get it off the engine mount bolts, and slide it forward, no? I couldn't see how to get the engine mounts completely off, as the rear bolts are not accessible. If I could get to them, it would just be sliding forward.

I'm a little concerned that this will pop loose from those bolts and pitch forward too quickly. Or, I'll pull it up too high, and bend something. Just a little unsure on how to proceed forward.

Any advice? Should I do it in the dark, by myself? Keep in mind the only engines I've pulled have been out of motorcycles. I'm in virgin territory.

BTW, I still think the throttle bodies look the same. Remember, OBDII to OBDII here. 97 to 99. Everything looks the same. Hell, the injectors look like they can plug in.

Correction, they're not the same. Finally pulled the new one off the 2.5. It does have a different port on back. I assume that's what needs to be blocked off, correct? Seems simple enough. Is it?

Hey, is there any way to use the IAC from the 2.5? I had an engine code on the 1.8 (cleared and came back) that the AIC was bad. sucks, as it's $300+. Can I maybe rewire the 2.5 TB to work with it's IAC and avoid the blockoff and all that nonsense?

is the 1.8 a 4 wire or 3 wire? if its a 4 wire (ive never seen an OBDII 1.8) it might work on the 2.5 throttle body.

TADA!

All by myself. Lift a little here, slide forward a little, drop back down, lift the other side. It was pretty backyard, for sure, but it's out. Actually, easier than I thought it would be.

Oh, yeah, I had the chain spun around 180 degrees when I hooked it, so it flipped around once I got it free. Yep, I'm proud I have no idea what the hell I'm doing. Oh well, it's coming along. I'll probably post more this evening, if I make progress.
