SubaruForester.org has an entire section dedicated to tires including spreadsheets and feedback. IT's worth cking out. Tire Rack has a great website with reviews also.

I didn't realize that - when did they stop using STI blocks?

I hadn't heard that either. Only change I had heard of was VVT to AVCS. 06 had revised HP figures from 210 to 230. Then again, I haven't followed the XT changes closely.

STI block by dstew1

Only the '04 and '05 used the STI block. The '06 moved to the WRX block in conjunction with the WRX going from 2.0 to 2.5L.
 
The 210hp numbers for the '04 and '05 are widely viewed as Subaru sandbagging on paper so as not to offend potential buyers of the WRX (rated at 227hp at that time, I think). Then in 2006 it was corrected to 230hp, and from there it has dropped a little I think only due to changes in calculation methods. Nothing has really changed with the engine since its inception, other than the switch from the STI block to WRX block as mentioned above.
 
Essentially each year puts out about the same power in stock form, with the STI blocks maybe having a case for being a safer engine to modify to super-high power levels. However I think there have been slight gearing changes over the years (check the cars101 website) that has slowed 0-60 times a little in order to improve upon fuel economy.

I ditched the Geos on my 06 XT at 18K miles in favor of the Potenza G009s and haven't looked back. No squealing, much improved handling on dry roads, more stability at high speeds, and better at everything in the wet.

I've got 23k on the Geos and they're ok, as long as it doesn't rain. I'm planning on moving to high country soon and am going to need something that does great no matter what. How do those G009s do in the snow?

Thanks for the info. I'll check it out. I've got another one for you folks. A tech at the Subaru dealer told me back in March I shouldn't be using synthetic oil. I told him in was in the owner's manual and didn't see the problem. He asked my question at the April technician school and was told synthetic oil was bad for subie engines. It was something about it drained off the heads too fast. Does this make any sense? I've been running Syntec since the first oil change.

Didn't really get a chance to run the G009s in more than a couple inches of snow last winter (mild one here in Arkansas), but I found the traction in those conditions to be pretty good.
 
Check out some of the reviews on Tire Rack; I believe there are several that mention the bite the tire seems to have in the snow. It also received excellent snow/ice scores during testing (note it's only scored against other high performance all seasons, not dedicated snow tires).

My other question is this. Sometimes when taking off from a stop, the tranny will shift in the highest gear as low as 20mph, causing me to hit the gas a little harder to get going. Is this normal? I've noticed this many times and have just assumed it is normal. Is it? Does it do any harm to use the shift lever and shift manually?
 
There is no harm to use the shift lever manually in the 4EAT, in fact I've been told that is why it is gated. I would suggest for stop/go driving around town where you'll be keeping it under 40 or 50mph, select "3" instead of "D". This will keep you out of 4th gear and makes it easier/quicker for your tranny to downshift into 2nd under harder acceleration.
 
Also the 4EAT is adaptive, so if it's behaving a certain way, that is largely due to your own driving habits. Driving aggressively will result in higher shiftpoints and quicker downshifts; driving like a grandma will result in quite the opposite.

You sure about that?
 
I was told the Forester XT (2.5T engine) had the STI block, so it was the other way around. It has the semi-closed deck block, like the STI does.
 
Also, when they went from 210 to 230hp, the peak boost did increase a little. I do agree the early 210 hp models were sand-bagged, big time, and made more power at the dyno than the 227hp WRX 2.0T did.
