I would run 10w30. The tolerances of the newer engines are tighter, so they need to run thinner oil. Plus it's more fuel efficient.

They did make FWD's. They should be swappable.

Do you have any wiring diagrams? You need to check the pin outs for the two TCU's to see if any pins are different. It's possible things are different, which is why you're having issues. Also, you need to make sure the connections are the same at the connector that hooks up to the transmission.

What year and model car???? I really would highly recommend against going one step colder plug on a relatively stock engine. Your gas mileage will be crap, the engine won't run as good, etc. If you truly think your car is "pinging" run higher octane fuel. If that makes no difference, then I don't think you're hearing any pinging. Can you describe what you are hearing/experiencing with some detail.

What year and model?? The a/c compressor can be on when the HVAC system is on Defrost or Defrost/heat, as well as A/C

Check out my site. It has the procedure on how to read the codes and what they are www.surrealmirage.com/subaru/engine.html

I just got generic STB's from ebay that were meant to fit a GC impreza

Exhaust ports are the same. You'll run into more issues with the electronics. The first gen legacies are OBD1, your forester is ODB2. There are some possible solutions, but it's not a "plug & play" type thing.

Is the check engine light on? Do you have any codes stored in the ECU?

May want to post on http://www.rslibertyclub.org/forums/index.php They may know

I changed the title which may help in getting responses. If you don't get any responses here, I'd suggest asking in the tire & wheels forum on nasioc http://forums.nasioc.com/forums

Welcome. We've run across this numerous times with the coolant temp sensor, which is why I recommend it. It's a cheap part, and can save you a ton of headaches if it is the problem.

Yeah that is nice.

Yeah....there's a connector that snaps onto a part of the sensor. You just push the connector part down, and pull/wiggle the connector off.

The normal belts or the timing belt? You should be able to see the normal belts right in front of the engine. The timing belt, you can remove one of the end timing belt covers and take a look at it.

The six speed manual tranny found currently in the sti's is the only US production subaru to disengage the rear drive when the handbrake is engaged.

You may want to post in the meet & greet forum as well.

any of the online subaru dealerships should have a canister purge solenoid I've used www.subarugenuineparts.com with good luck.

Not sure if this will be of any help, but it's worth a shot. http://www.randomsoup.com/subie/ Hopefully someone else will chime in

Does the whistle change pitch with speed?

How bad are they? You should be able to buy touch up paint at your subaru dealer. It probably won't be perfect, but it should be good for touch up.

Trying to use an EJ20TT motor on any LHD car will prove to very difficult, and not worth the time and money. You're better off getting a single turbo setup. However, the EJ20TT motor should bolt up to any newer style EJ series transmission.

You shouldn't have to put the engine at TDC, you just need to make sure the timing marks on the pullies are aligned to how they're supposed to be aligned when doing the timing belt. I haven't done a DOHC timing belt, but on the SOHC ej22's, you just align the marks on the cam pullies, and crank gear, and swap the belt.

They should be interchangable. Changing the 95 over to a hydraulic clutch "shouldn't" be an issue. The clutch fork is different between cable & hydraulic. So you'll just need to take those parts from your 98 trans, and re-use them on the 95. Also, I believe the pivot ball for the clutch fork will need to be changed. There are two bosses in the transmission case. Look at both transmissions and verify the pivot is in the same spot, or if it's not, you'll need to move it. This may require you tapping the bosses. Only other thing to note would be speed sensors/speedo cable. I'm not sure if the 95 has a speed sensor, or uses a cable. I'm pretty sure it uses a speed sensor, so it shouldn't be an issue. Otherwise, you should be able to remove the cable and put in the speed sensor...

Have you tried resetting the ECU, and seeing what codes come back on the 93? I'd agree with nipper about the coil pack on the 90.
