As for breaking engines in. We here at Ford's dynamometer lab still break-in engines, so our modern engines still require it. But each engine might require a different amount of time. So just read your owner's manual, because the company that wrote the manual knows the most about the engine. Reading the manual is a very good idea, and the repair manual straight from the mfg'er is better.
As for warming up the engine. Idling for 60 seconds is probably neither harmful nor helpful. But you certainly don't need to do it that long. Idling actually warms the engine very slowly, when the goal is to warm it is as quickly as possible. Warming the engine completely is one of the best things you can do for it. And the best way to warm your engine is just driving off after you start the car. At Ford's dynamometer lab, we give the engine about 30%-40% throttle and hold a low RPM like 1000-1500. That's the same as you running in high gear and accelerating moderately.
Ottos, very good info on break-in and warm up. The "pre-oiler" feature you mention is available from racing supply companies like Canton-Mecca. It is a rather elaborate and expensive set up, but it might make sense for megabuck racing engines and the like. I just follow the manual, allow a brief period at startup to get all the fluids flowing, and drive gently until I have some oil temperature. I also run full synthetics like Mobil 1 and Redline, and change them religiously at 3K miles along with the filter.
I switched to Mobil 1 Synthetic in my Passat Turbo when I hit 23k miles. This was conveniently when my "free" VW services were finished. I experienced about a 2mpg increase in average MPG, noticably smoother running, and noticably easier cold starts with the switch. In the 10K+ miles since the switch, I have experienced NO leaking, weeping, or excess oil consumption.
It is also nice to be able to change the oil less frequently. VW recommends 5k oil change intervals with conventional dino, I go 7500 with Synthetic. Synthetic's better resistance to oil line coking is nice too.
I think that if you are modifying your car at all and pushing more boost than stock, then it would be useful.
Otherwise, I don't see the point either. The money would be better spent on a turbo-timer.
Another useful gauge to have on modified turbo cars is an EGT (Exhaust Gas Temperature ) gauge. This gauge is mostly used to ensure that the engine is getting enough fuel at wide open throttle/high load/boost/rpm conditions. Not enough fuel causes a dangerous lean condition which could cause detonation(excessive knocking) and extremely high temperatures which could melt or crack pistons, valves, head gaskets, etc.
EGT gauges are often used in conjunction with larger injectors and an air flow computer such as an APEX Super AFC. It allows you to tweak the injector cycles to increase or decrease fuel flow into the combustion chamber at a given rpm and throttle position.
And I agree with silver_bullet. Whether you're quibbling over $500 or $1,5000 to get what you see as a good deal, the feeling that you got a good deal on a car will last as long as any 60 month loan.
I think with a good cold air induction kit and better exhaust, you can yield some pretty darn good power from the WRX. I would say 250hp is quite easily obtainable with a few hundred dollars.
Many American are happy to look like they could go fast, if .... And, with the way most of my fellow commuters drive, I'm glad they don't really try!
Take care.

Earn the sale by offering negotiation. If car dealers don't clean up their image and reputation then pretty soon you guys are going to get bypassed when people start buying cars direct from the manufacturer.
I love the location of that intercooler. Although it somewhat limits the size of the intercooler as far as potentional upgrades go, it's proximity to the windshield washer lines begs for a home-made water sprayer system. The washer fluid reservoir is pretty good sized too. The one on my current car probably holds as much fluid as my coffee mug.
If you look at the intercooler of the WRX, you can see that it's slightly off to the leftside (driver side). It leaves some space for the hood scoop to draw air to cool the turbo itself! Pretty neat desig if you ask me.
Just a side note. Don't be afraid to run your engine hard sometimes. The wear to the engine is not much more than ordinary driving. I'm just saying this so you can enjoy your cars the most. It's not hurting it, but it is even helping it. When the engine is first started, soot forms and some fuel leaks into the oil in the oilpan. There could be some condensation in there too. With high-load operation, your engine runs hotter and you burn off the deposits. Also your oil gets hot, evaporating the fuel and water.
So take your engine to the gym and work it out. unless it's sick.
Speaking of longevity, another thing that you can do, especially during the hot summer months, is maximize the efficiency of your engine coolant by raising it's boiling point. Coolant fluid temperatures in turbo motors relatively get much higher especially if you have a water(coolant)-cooled turbo. During heavy throttle use, you can minimize localized boiling and overheating of coolant passing through the turbo by using coolant additives like Redline Water Wetter. Boiling coolant (steam) is less efficient than coolant in it's normal liquid form because there is less contact and heat transfer between the metal and the coolant. Maximizing the cooling properties of your coolant will make your turbo last longer and your engine as a whole. And just like what a previous post says, use synthetic oil and change it regularly. Always, always, always warm up the engine before driving and let it cool down before shutting it off. Believe me, you will remember to do all of this after the first time you pop the hood at night and see that the exhaust manifold and the turbine housing are glowing red.
Turbo gauge, you want to see the max boost, and just as important the vacuum at idle. Oh yeh you want to know if you are running over boost:

I dont think everyone needs a gauge pack, but for those used to it (Talon/Eclipse owners), and those who are talking about increasing HP, it's a no brainer. Most T/E owners have two, the inaccurate stock one, and the one they added themself.
also- why does a car forum not know "turbo" is a word in its spell check
The Impreza is going to be a exciting vehicle to drive and modify, Can't wait.
It has 300hp turbo intercooler engine and 6-speed manual transmission. 0-60MPH? within 4.5sec.
In WRC(World Rally Championship), it is a real dark horse.
Reliability? I have no idea but.. maybe Hyudai's 10/100,000 warranty will be applied.
Price? should be cheaper than its competiors.

Have a safe driving!
If I get a Rex, it will be a blue or black sedan, no wing, and I'll keep the stock 16" wheels. I *might* lower it an inch on stiffer shocks and springs when the first set of shocks wear out though.
I like "sleepers." :-)
Heres a suggestion: BBS lookalikes: Do the Impreza RS test at www.discounttiredirect.com and check out the "Wheels" page "Interactive Wheel System (requires shockwave)", Go to: "Subaru/Impreza/Sedan" (You get to see somebody else's wheels on your car before you steal them).
Look at the following models starting at $949 including performance tires: MAS Callisto 17" KONIG Rush 17" ENKEI TBS11 or ENKEI RMR (I believe the ENKEI's are ringers for the BBS's).
Hard news: There are 175 vehicles scheduled to deliver to Midwestern stores and 161 have been sold. The dealers apparently don't get the car delivered without a buyer commitment. Best Regards.

Lest we forget, the Subaru doesn't exist in a vacuum, even in the States we did get that Toyota, as well as 911 Turbos, the Saab 9000 Aero, the Volvo T5s, T5Rs, and Rs, the old Omni GLHs and Mazda 323GTXs in the past. Let's just hope that VR-4s, Evos, and Skyline GT-Rs follow the WRX.
I have an Impreza RS 2.5 and was wondering if I can add a turbo to it and atleast bring it upto par with the WRX .....
any suggestions?
have a nice day,
jawahar
There you can find many Impreza fans and some do turbo their cars. With moderate boost levels, you can be in WRX power levels and I know a few who gone further and is pumping out 250-280hp with their normally aspirated Imprezas.
