  1. That's because they're wussies! Voodoo Engineering baby!
  2. Hmmm, that's interesting. Mine hasn't shut off yet after several thousand miles of driving, and I only had to add/connect two sensors outside of what was contained in the disty and intake setup. (Only one of those sensors was an absolute requirement for it to run.) EA82 cars: it's a cakewalk EA81 cars: you have to modify the disty a little EA71 cars: quite a lot of work because the intake manifold won't cross over. And yes, the stock Hitachi carb, when it's in good shape, is great as far as fuel economy is concerned, but SPFI has better drivability and more power.
  3. My brand-new out of the box Weber fit the exact description of Tim's back when I was running it on my car. Good low end, but not much top and abysmal fuel economy. I used the stock Subaru fuel return line and fitting.
  4. It is unlikely that putting a filter in the return line will create enough restriction. You should be able to find a pressure regulator that only allows fuel to flow through the return line once it has reached a certain pressure.
  5. Could you describe the hesitation a bit more? I.E. is the tranny slipping? Does the engine sound like it's bogging down with too much fuel? Any other noises? My 91 I had for a while would bog down sometimes, and my car does it occasionally.
  6. I was considering an EJ swap a while back, and I would beg to differ with the opinions that have been presented so far. Obviously, the EJ22 produces more power. We know that. However, I talked to Austin and he told me that the EJ18 powered Impreza he used to have was comparable in performance to any of the EJ22 cars that he had experienced. Also, remember what vehicle the engine is going in to. Your brat makes 83 horsepower right now. 110 is a substantial increase. The extra 30 horsepower from the EJ22 is more likely to break stuff than make you go faster, especially when you consider the fact that your tranny is more than 20 years old, and it as well as the axles/joints were designed to hold up with an 83hp engine. It really does come down to what you want to do with the vehicle. Either engine will more than fulfill your likely needs, and will be a huge improvement over the EA81. Unless you can find an EJ22 for a similar price, I would go with the EJ18 simply because of the cost factor.
  7. Yeah, high speed runs in the cat boat would definitely be restricted to calm days. Anybody here see that episode of Junkyard Wars where they built a powerboat out of fuel drums and dropped in a big old Land Rover diesel? So many ideas, so little time....
  8. True Dat! I haven't even run in a rallycross as there isn't any of that cool stuff up here, but I can definitively say from my misadventures that tires are the best way to spend your money. Think of it this way: Take a WRX making 200-some-odd horsepower and put street tires on it. On gravel and mud, you'll be lucky to put down 80 of those horsepower. Then take an RX making 100-some-odd horsepower but put some awesome rally tires on it, and you'll put down close to that 100-some-odd horsepower. In that situation, the RX is likely to be as fast if not faster than the WRX due to much better control and traction.
  9. Have you checked the float level and travel? Maybe the fuel level is simply too low in the bowl.
  10. Converting to the factory SPFI system is REALLY easy. I recently finished a manual detailing the conversion. Hush777 has scanned it, and it should be posted in the USRM SOON! I did the conversion in two days the first time, and I'll never go back. Drivability, power, and economy are all improved over the stock carb, and compared to the Weber I was running, drivability is WAY better and economy is significantly improved. If you've either got access to a good junkyard or you can get an EFI parts car, the conversion is inexpensive. It cost me less than when I converted to the Weber carb last year.
  11. Ditto what Arch said. Take care of it, and it'll be fine. Turbo cars seem to have more issues than N/A ones, but that's just because they are less able to take abuse in conjunction with lack of maintenance than the N/A cars.
  12. After following the threads on subie powered boats, I got to thinking about some other ways to do it. In SE Alaska where I live, air boats are extremely popular for getting around in the shallow rivers. I've also heard these craft called "fan boats" because that's basically what it is. You take an airplane engine and prop, and stick it on the back of a small aluminum boat. So I was thinking maybe I could take the EA81 sitting behind my shed, somehow mount a prop to it, stick it on a boat, and go like mad. Anybody tried this or seen others do it? The other idea that came to mind was a high speed catamaran. Picture this.... Two skinny little hulls that are just big enough to keep the thing afloat, joined by a couple of cross braces. Stick an EA-series motor in the middle connected to a high-speed prop, either direct drive or through a transmission so that you could gear down for starting off and run a really big prop. Is this crazy talk?
  13. The SPFI conversion is a cakewalk if you know much about cars and electrical stuff. I did it for the first time in less than two days of tinkering. The biggest advantage injection has is drivability. Carbs can make more power in many cases, but they have issues with weather, altitude, and vehicle inclination that EFI avoids. In my case, I would have to tune my carburetor five or six times along the way on my drive between home and college in order to get maximum performance, whereas my current EFI setup does it for me.
  14. I like Archemitis's idea of getting frozen up. Try opening the bleeder screw and see what happens.
  15. I think you mean EGR light. It comes on every 60k miles (it's on a timer) to let you know that it's time to clean and inspect the EGR system. On the EA82 models, the you switch a set of connectors under the dash to reset the timer. I assume it's the same on your car, but I don't know what the connectors look like. Try cleaning the carburetor thoroughly, and verify that the choke moves freely and that it's getting power.
  16. Try gravity bleeding. It's often the most effective at removing stubborn air, which you want to rule out completely before throwing a MC at it. Just open the bleed screws and let it sit for a couple of hours, topping off the fluid as it goes down. Also, make sure you bleed where the lines connect to the MC, just to make sure that there is no air in there as well.
  17. Aha, so if you were to hook up an A/F mixture gauge and watch it like a hawk, you could theoretically boost above the fuel cut without any problems. Here's an idea: Lots of cars use a cold-start injector that adds more fuel on demand. Would it be possible to retrofit something like this into the intake manifold and provide some way of managing it? That way, you could do the previously discussed mod to eliminate the fuel cut, then have this extra injector turn on above that point, more or less taking over fuel control once the factory system has maxed out? I know there would be some substantial work involved in order to control this setup, but I'm just throwing the concept out there to see if it could possibly be viable.
  18. No s***? How does that work? Did you get a factory service manual? It's the ONLY way to go when delving this deep into an engine. For hi-po parts, check out cobbtuning.com. You might consider getting the pistons coated. For info on that, check out the thread in the old gen forum called "EA82 Rebuild Digest." A guy from Fairbanks recently did his EA82 and found a place that does coatings for pretty reasonable prices.
  19. That makes sense. So if the engine will start to lean out, then why would anybody in their right mind want to do this?
  20. I'm amazed more people haven't noticed this. Maybe our gas here sucks or something. My car has had lifter problems, and it's not that. The sound accompanies load/throttle just like preignition. One of the engines that I tore down had been known to have a propensity for making the noise, but there was no indication of damage to the rings, pistons, head, or even the spark plugs. Very confusing to me. I have found that my car almost never does this now that I have converted to SPFI. Maybe it is associated with the older-style disty that is used on the carb cars?
  21. I seem to notice a LOT of carbed EA82 subarus making what sounds like a ping/knock noise on a pretty regular basis. If that was the case, I would think they'd fall apart in short order, but nothing bad happens. Is the noise something else?
  22. My weber had similar issues. Just didn't seem to atomize the fuel right or something. What's the history of the carb? New? Rebuilt? JY?
  23. Do you mean that you steer with a tiller rather than a wheel? Are other subaru engines used? EA71, EA82, EJ18, EJ22.... Maybe even a twin-turboed JDM EJ25....he he he:brow:
  24. You should be set for quite a while now. If you take care of this car it will take care of you.
