My Magnecor wires were a fair bit longer than my original wires. They're also silicone-insulated, making them extremely flexible. As a tiny bit of insurance against their popping off, I gave them a lot of slack just by the coil pack. Maybe this might help?

I've only had the wires on for a very short time, so I can't say yet whether that problem will come up. I did notice that the coil ends of the wires really didn't have any kind of locking mechanism to keep them in place. Moreover, the coil towers on the coil pack itself are tapered, which would make...

Santa brought me an MSD DIS-2. He also somehow made it possible for me to find a Diamond coil pack on a junkyard '90-'91 Legacy for $6. :D

I know this is an old post, so maybe you've found more out since then, but anyway... As far as I know, the ECU cuts fuel if boost pressure exceeds its threshold of safety. The ECU also operates the wastegate control solenoid to bleed pressure away from the wastegate in an attempt to achieve its desi...

At worst you might have to replace the crimp-on terminals and the spark plugs. I don't know how much the terminals are, but NGK copper plugs are like $1.50 each or something... If you do find signs of arcing, you might just try replacing the plugs and filing the terminals clean rather than replacing...

No problem, just hope to help out... You should be able to tell if the current has been arcing between the wire and the plug by looking at the metal terminal (by shining a flashlight into the boot) and by looking at the end of the plug. Look for streaks or scorch marks, or other obvious signs of hig...

I just finished setting up my new ignition system. Diamond coil pack, Magnecor 8.5mm wires, NGK copper plugs (I had misguidedly put Bosch Platinums in before), and an MSD DIS-2. I have to say, the car really seems to pull harder, especially at low engine speeds. Magnecor wires seem to have a reputat...

I wouldn't think you'd want to use nonadjustable Impreza struts on a Legacy, though; the rear struts of a Legacy support almost as much weight as the front struts of an Impreza.

I thought that was normal. Isn't it?

The turbo probably does speed up just as you release the throttle. The pressure on the wastegate actuator line would drop suddenly, so the wastegate would slam shut. This would only be transient because with a mostly closed throttle the turbine wouldn't receive enough energy to sustain the speed. Th...

I have a hypothesis: I'd bet that exhaust gas temperatures would go up with this mod. Can anyone verify or refute this? The reason I'm thinking this, Aaron, is that you say the car isn't as fast, loud, and spools slower. You could easily remedy all of these by installing a ball-and-spring manual boo...

I have not done this mod, and do not ever plan to. I think it isn't a good idea, at least with an otherwise stock setup. The compressor outlet is the right place for the wastegate actuator to read boost. The ECU measures manifold pressure when deciding how much air to bleed away from the wastegate a...

An option other than finding a 50-watt 15 ohm resistor would be to get multiple lower-power resistors.

It'd get impractical when you end up soldering a hundred 1/2-watt 1.5-kilohm resistors in parallel, but...

A pair of 30-ohm 25-watt resistors would be decent.

Sounds like a good plan! It looks like you're aware of the issues you'll need to tackle. Basically, you need to know how the ignitor works in the WRX and wire it correctly. If the WRX has a four-channel ignitor (which would make sense to me) you just wire each pair in parallel; the ECU's ignitor out...

Here's where I read it: http://www.endwrench.com/pdf/elec/FtIgnitionDiagOpS00.pdf "The solid state igniter is located on the firewall on early Subaru direct ignition systems, and is integrated into the coil assembly on more recent Subaru vehicles." The document goes on to describe it in a ...

ciper: I did the Buy It Now (tm) deal. Some other guy outbid you before I did that though. You may be right that the ignitor's not integrated, but I'm pretty sure I read somewhere that it was. Off the top of my head, I don't seem to remember seeing one in the middle of my '97 Legacy GT or '97 Imprez...

I'm wondering, with this talk of replacing coil packs with later-model Subaru coil packs... I have a little plastic housing containing the igniter (ignitor?) in the center of my '93 Turbo's firewall. This is basically two big ol' transistors. My understanding was that at some point along the line Su...

From what I understand, you should be fine, unless you have other problems to begin with. When I put WRX rims and tires on my '93 Legacy Turbo they scrubbed the wheel wells in the rear a tiny bit on sharp turns. I'm pretty sure my rear springs are worn out, though, since I left a lot of weight in th...

The harness connector is different from the newer Legacies and Imprezas.

I believe my '97 Impreza L and my '97 Legacy GT both had the same connectors on them, but my '93 Legacy Turbo is different.

I've also had success putting jackstands under the sway bar mounts. The saddles of my stands fit the shape of the mounts really well. This doesn't work so well in the rear, though, since the mounts are up way higher than in the front.

Yep, the IAC valve is just below the PCV valve. The top of it is a little plastic rectangle-like thing mounted in place with two screws. I actually haven't really found it documented anywhere, but the IAC valve is adjustable. You can adjust it in place if you remove the plastic coil cover and the li...

Legacy777: What's the procedure for bleeding the master cylinder? I looked before for a bleeder screw under there and didn't see one. rallysam: I think I let air get in through the master cylinder once when I didn't top it off properly while bleeding, and I ended up doing one complete round of bleed...

If your '92 has the same master cylinder as my '93 (which it almost certainly does), I believe the part number is 37230AA011. Subaruparts.com lists it at $150.
