This might be a little off topic, but have you considered the frankenmotor? It's more powerful, just as reliable, and the sohc heads weigh less. I'm an aviation nut so i think of these things.

My Rockers are Roller/Hydro. I'd like to put this ej18/22 head debate to an end. Are they the same or are they not the same? I mentioned the valve and port sizes on my heads. Does anybody have any ej22 dual port heads to measure? I do know that the single port heads have bigger valves, right? Maybe that's causing the confusion. Also, I need a source for the oem o-rings that go in between the block halves. I'm going to call my local dealer tomorrow, but is there a place online to get them without buying a whole gasket set.

Would you be willing to part with a couple of those washers?

I've heard some say they don't and some say they do. But, it wouldn't make sense for subaru to have two different castings to manufacture.

The intake valves on the heads i have are 31mm, the exhaust valves are 28mm. These are dual exhaust port heads and each port measures 1 3/8. What do the ej22 heads measure? I did a gasket match to improve the flow a little, but with delta torque cams this won't be a high rpm motor.

Alright, so I'm jumping on the frankenmotor band wagon. I was given a free 2.5 block and since I've always wanted to rebuild a motor I'm going to rebuild the shortblock and my ej18 heads that I'll be using. I've heard some horror stories about ACL bearings and I'm now weary about using them. I found some clevite bearings on rockauto.com for $31. Seems a little cheap, are they any good? And on my heads the rocker assembly seems to be missing one of the spring wave washers. I can't for the life of me find a replacement. Where can i find some? Or could I put a regular washer there as a shim?

Ok, here's a little update. The plugs I were looking for were the ones that go into the ECU. I got my multimeter out with the intent of checking the resistance of the wires going from the ECU to the mass airflow sensor to make sure it was within factory spec (less than 10ohms). Turns out I couldn't get continuity on one of the wires going from the ECU to the mass airflow sensor. Do you think I should run a new wire up to the mass airflow sensor from the ECU?

So, where are connectors E25,E30, and E31 located? I need to know so I can do the diagnostic procedure outlined in the factory service manual.

My alldata manual shows plugs called E25,E30, and E31, but the FSM dosen't show those plugs. Where are they? Also, where is the CTS? It's supposed to be E5 on the last picture, but I couldn't find it on the car.

Ok, so here's the codes I got. 21-Water Temperature Sensor. 23-Airflow Sensor. 31-Throttle Sensor.

Ok, I was planning on getting the codes on my day off tomorrow anyway. I'll let you guys know what I find.

I forgot to mention something. The engine will only rev to about 4000 RPM then it's like it's hitting the rev limiter. And I got broke down on the side of the road, please help.

So, I've recently acquired a 1995 Impreza Outback EJ18. I'll spare you guys the complex background story. Basically we got the car with the title but no key. So we took the lock cylinder out and have been starting it with a screw driver. Are the lock cylinders different between the 1.8,2.0, and 2.2 (probably not but, just to make sure.) How much would it cost to make a key for the doors if i don't have a key to make a copy from? Now for the interesting part. When we got the car it would start and run for 3-4 seconds then shut off. The previous owners had replaced just about all of the sensors under the hood to solve the problem. We tried taking the ignitor off another car and it fired up and stayed running. We put the old one back on it and it stayed running then too:confused: In fact I drove it back to my house(a 2 hour drive) no problems. What would cause that?

Ok, here's a little update on my problem. When I finally got some time to work on it, I pulled out each fuse individually and checked them. Two of them were blew so I replaced them, turned the ignition on and I heard them (the same two) blow again. At this point I studied my wiring diagram and looked for those fuses. I noticed the plugs for the automatic transmission (which I recently replaced with a 5 speed D/R:)) were a part of those circuits. So, I popped the hood and went to inspect those plugs. Turns out one of them was broke leaving the connections inside exposed. It was grounding out on the engine. That's why it kept blowing fuses. :cool:

I just checked them and they're fine.
