This is the correct diagnostic method, to see if the TCU is telling the transfer solenoid to activate. Even though you've changed the transmission, I'd still bet it's the solenoid and/or clutches. This was such a common failure, when I worked at a Subaru dealer, we stocked all that stuff (Duty C solenoid, clutches, and all gaskets).

As mentioned, you don't need the XT6 crossmember. And to my knowledge, aftermarket clutch kits no longer offer an XT6-specific option. I'm not terribly sure what your clutch options with the EA81 trans are, I thought the Nissan throwout allows you to run an EA82 clutch, which should be a bit better than the EA81. But I haven't played with EA81s....so take a big grain of salt I would definitely recommend the SJR adapter plate. He does a good job machining, though I've done several flywheel modifications myself. If your Impreza is an automatic, you'll have an easy pattern with the little spacer on the flexplate (otherwise, get on a local Subaru facebook group, and/or the classifieds on here, and you might be able to get one for cheap). A high-speed cutting bit on a dremel does very well (I think I bought 3 of them, but probably could have done it with one). The center hole will center it perfectly on the snout of the engine, and orientation no longer matters. Just ream them out until you get all 8 bolts in. Unless your other Brat is a turbo, it won't have an adequate fuel pump either. You'll need a fairly modest fuel-injection pump. Far easiest to get something designed to be mounted inline. I've used stock EA82 replacement ones, I used one for some old Ford station wagon once. If I were doing it now, I'd get on Summit racing or similar and buy a universal inline one. Yep, EJ ECU has fan control outputs, just wire it to a relay, and that to your fan, you'll be golden.

I couldn't have said it better myself. LEDs have a smaller output point than a halogen filament, whereas HID is a larger point. Completely different challenges, and the findings with one source are irrelevant to the other. Thanks for backing me up.

Fantastic article about HIDs. Pretty "awesome" how it's full of assumption that LEDs are exactly the same, even though they aren't. Kind of discredits the entire article..... We've done this before, and I'm not going to get into it again. I'm anal about headlights, and have used LED retrofits with fantastic results. They can work wonderfully. I will concede that if the bulb isn't made correctly, it won't work right, and because it is a bit different, it's possible that results will vary with different lenses.

I didn't really see that when I worked in Subaru parts (I left last summer). Certainly not the normal wear items. Yes, occasionally someone would be looking for something odd that wasn't available anymore... But yea, OEMs don't generally have much available after about 20-25 years (I can't believe how much Toyota has for my '91 and '87, and Ford can't even look up my '94).

Yea, an engine uses the smallest amount of fuel at idle. So if your 440 uses 2-4 lb/hr, the EA71 probably uses about .2 lb/hr. BUT, if they say it can handle it, than I wouldn't worry about it. No, I don't know of your valve question. I have zero hands-on experience with stuff older than EA81s (and even that, just barely). Yea, the fuel system is relatively simple. I don't know those kits at all, but converting it to a high pressure system is relatively straight forward. Just make sure everything's rated for high pressure, and you have an adequate return.... Thanks for following up after calling them. It's good info. Assuming you end up making the conversion, start a new thread with some information on your setup and I'll link it in the FAQ

Yes, that's how fuel injection works. The ECU opens the injectors for varying amounts of time (the flow rate of the injector and pressure behind it determines the volume of fuel that passes through in that time) depending how much fuel the engine needs for that revolution. A programmable ECU can further be adjusted to accommodate different engine sizes and other variables (like forced induction). The question is if the ECU and Injectors are capable of accurately opening for a short enough time to supply a small enough amount of fuel to run that efficiently. I wouldn't bet either way, but it's enough of a question that I'd want an answer before I plopped down over a grand. On the top of the page, is this text "ASK OUR EXPERTS: 1-866-464-6553". I bet a person could call that, and ask if the Sniper EFI 2300 can control a 1.6l 4-cyl making about 75hp. And they'd have a real quick answer for you.

Yes, Subaru mechanics lift from the pinch welds. So you're lifting with a scissors jack on the pinch weld, and setting on a stand? Yuck, that sounds miserable. I've been using one of those ~$75 aluminum jacks for 15 years. They're SO much easier to work with, and really not difficult to move around and/or store. On the newer multilink cars (yours is one of those), I straddle the 2 bolts for the subframe brace (the 2 bolts pictured, not the one holding the plastic on) with the saddle of the stand.

Mechanically, easy. Electronically.....well, as they say, "if you have to ask." AFAIK, all the 5EAT cars had immobilizers, which means the TCU is looking for a CAN signal from other modules, which will be virtually impossible to make happy outside the car for which it was designed. Probably would require a standalone auto trans controller (which I've never seen done on a Subaru transmission, those controllers generally are not designed to control AWD as well). And quite a bit of custom programming. 4EAT is a decent trans. I don't like the standard AWD system, but there are models with the VTD on the 4EAT.

This Coolant flows through the IAC and Throttle body to prevent icing. Almost every manufacturer does this (some through the EGR valve, as well), yet in real world situations, they very rarely ice up (here in Northern MN, we see some of the coldest temperatures that a car might have to deal with, and I've bypassed this system many times).

This, SPDT. I used a pushbutton shifter from a PT4WD Loyale to control the center diff lock on an RX FT4WD transmission, and it's a very simple circuit. SPDT switch provides power to one of 2 solenoids by the LH strut tower.

It's certainly possible. It all comes down to how fast the injector actuation is, and how quick the ECU processor is. That pump and injectors are certainly considerable overkill, but that doesn't mean it can't work on a smaller engine. But that probably is the only big hurdle. Might be able to shoot a quick message to Holley and see if they think that hardware would work on an engine this small or if they can supply smaller injectors. Probably a quick answer for someone that knows.

That will regulate the fuel pressure going to the injectors. The problem comes with the fact that it has 2 100lb/hr injectors, when you turn down the duty cycle on those enough for a 1.6l engine, they will not have very much resolution (how much is dependent on the processing power of that little ECU). https://fuelinjectorclinic.com/flow-calculator Punching some quick numbers (entering 2 cylinders, as it seems to be calculating it based on one injector per cylinder), assuming you make about 75hp at the crank, You should be running about 20lb/hr injectors, but that kit comes with 100lb/hr units. If the Injectors can be replaced with smaller ones, it would probably work very well.

Very good question, and sounds like a great project. I've seen one of those Holley kits used on a domestic V8 and it seems like a really cool option. I have not seen one used on a Subaru. As such, I'd recommend starting a new thread in this section, it'll get more visibility there. EDIT: just noticed that you already did, I got a notification of a new post here and got ahead of myself. Carry on.

Then you'll have to get a 2 port one and a pair of splitters. Same function, but much easier to find.

The control arms and steering rack have to go down with the diff, so it's generally easier to use the stock crossmember there, and then build pads for the motor mounts above that. IIRC, I don't think 4" is enough to safely clear the front diff under the transmission.

They are the same displacement engine, and the same basic engine layout. But different in almost every detail. Turbo is DOHC, non turbo is SOHC. Turbo has a semi-closed deck block and lower compression. Non-turbo is open deck. Yes, hood scoop feeds an intercooler. Transmission is similar, but different. Gearing and AWD differences. Suspension is similar, but stiffer, etc.

Man, I respect your methods more than almost anyone else who posts here....but yikes. I would definitely call the bare connections at the alternator and A/C compressor sketchy (though I'd guess that that's been done since you had it). But beyond that, I see so many un-covered, and what appears to be unsupported wires. And hearing that they're a relatively high-amperage headlight circuit concerns me even more. Left as-is, that stuff will chafe and short out. I also see 2 fuse/relay blocks (one in the spare tire well, and one in front of the LH strut tower) that don't appear to be attached. It'd be fine for a test-drive or even several, but I wouldn't call that done. Just my $.02. I do find this story hilarious, and I'm glad to see that it's fallen into some hands that will keep it in good shape.

There is a serial number by the starter, but I've never seen a way to search the databases by serial number (I worked at a Subaru dealership...I've tried, we could look up a VIN, and that would give a serial, but not the other way around). The newer engines had the vin etched into the vertical part of the block on the passenger side of the bellhousing, right next to the seam with the transmission. But I doubt this is new enough.

Here's the list of vehicles that came with that ignition coil part #: http://opposedforces.com/parts/info/22433AA230/ Yea, '93-'95 Impreza 1.8. I see someone who went to the trouble to make A/C lines to adapt the EJ compressor to the EA82 body. I see some sketchy wiring! Look at the alternator and compressor. Also what is the bundle of wires draped over the engine?! I see vacuum lines for the 4WD, so I assume it still has the FWD/4WD stock transmission.

I don't think I've seen AWD problems cause a vibration. Usually AWD failure, or binding. When I read that post, it sounds to me like it was driven with mismatched tires for a fairly short time. And if they were the same size, just a different brand, I would say it's probably fine. I would rotate the tires front-to-back, and see if the vibration changes (going from feeling it in your butt to your hands/steering wheel, or vice versa). Vibration is most commonly just tires out of balance. Otherwise it would be helpful to know when the vibration occurs (accelerating, braking, certain speed, does it change with engine speed or vehicle speed, etc.) as there are a host of other things that can cause a vibration.

Yep, Impact driver. For Christmas I got a pair of Craftsman impact screwdrivers (functions the same, but looks like a normal screwdriver). Looks pretty cool......I haven't used them yet, though.

I agree, most likely pressure switch But, if it's actually low pressure, and it has plenty of oil. These are the things to check. I think I'd check the oil pump first.

I don't know what the tire size is, but the bolt pattern is the same. Offset is extremely close. Wheels will definitely bolt on. I'd bet money (and I'm not a betting person), that the tire size is close enough. But find the tire sizes (Baja would have come with a 225/60r16 stock in the US) and run them through a tire calculator.

A gas engine needs 3 things to run. Fuel, ignition, and compression. Diagnose them individually. Getting the right gasoline mixture can be a challenge, but starting fluid is volatile enough that it's MUCH more forgiving. So that means you have a compression or ignition issue. Pretty unlikely to completely loose compression on all 4 cylinders so suddenly. So you're likely down to ignition. That means more than just having spark. It has to happen at the right time. Within about 10 degrees and you should get a pop. An EA82 will run on just the LH bank, as the distributor is driven off that cam, regardless of the RH side (I had a buddy that stopped at my house because his EA82 was even more gutless than usual, turned out his RH cam had seized). So you can assume that your problem is on the LH side. Unlikely that your ignition timing has changed considerably on it's own, but completely possible that the belt has. It's not terribly hard to pull the other timing belt cover on the LH side, and compare the mark on the cam pulley to the 3 lines on the flywheel. I bet it's jumped (I've heard of timing jumping as a result of bump-starting, so if it had a dead battery....).
