Here we have the followup to the rally-mimicking Impreza 22B STI that Subaru recently chronicled in its Vintage Garage series: the 2004 Impreza WRX STI. Displacement for the boxer four was upped from 2.2 liters to 2.5, and after noticing how many buyers had installed larger turbochargers on their WRXs, Subaru decided to bolt on one in-house. That gave the final product 300 horsepower and a 0-to-60 mile-per-hour run of just 4.6 seconds.

It was stiffer, it's body from nose to front doors was penned by Peter Stephens, he of the McLaren F1, it came with a driver-controlled center differential, driver-activated cooling spray for the intercooler and 300 pound-feet of torque. This is a curio from a time when, after a new WRX STI came out, you started poring through magazines to see how the Mitubishi Evo was going to respond. You can find out more about it in the video below.

      strap this park bench wing on the 2015 and they'll look the same. Love the 2004, hate the 2015. 10 years time and so little has changed. Still has ugly boxy exterior and the interior looks like a cheap POS.

      The '04 looks 100 times better than the '14

        How predictable, I knew clicking on this article I'd read a few "oh back when cars were good" comments. In 10 years you'll be saying the '14 looks better than whatever is out by '24

          If it's anything like current trends, such as Mercedes getting rid of the "wedge", then yes, cars now will look much better than cars in 10 years.

      This and the EVO are both very important cars and they demand respect for helping usher in the current horsepower war / muscle car era. They helped prove that horsepower wasn't dead (as we had been told) and that it was exactly what most people wanted. They are largely overshadowed now by the 500-660 HP monsters you can buy elsewhere, but they were a very important ingredient in the entire equation. Will Subaru step up 10 years later and debut something just as dramatic as they did in 04? Time will tell.

      Ugh, I flipped my 04 STi about a year ago. I miss that car so much. I'm looking at getting a 5-speed Baja Turbo and painting it WRB and putting some STi bits in it to make it a Baja STi to give myself some closure. 04 STi still possibly the greatest performance car of all time.

      The Evo in 2004 still murdered the Subaru STI any day of the week.The Subaru has a better quality interior,but on sheer performance the EVo everyday.

      I enjoy it from a performance and styling perspective, but it is not a cockpit I can enjoy.

      My brother's 04 STI had the left front axle nut sheer off at a Watkins Glen drivers school. This was the nut with the axle end and cotter pin still in it! It had literally cracked off flush with the hub! By the time his instructor level skills brought the car to a safe stop without hitting anything the caliper, rotor, hub and bearings, etc. were all toast. A metallurgical lab I showed the axle to suggested a stress riser in the threads may have weakened the end of the axle. Normally not even an impact with a wall will sheer off an axle nut so cleanly. It just doesn't happen. There has to be a manufacturing defect for it to just break off like that. The car had 19K on it and was still under warrantee. But it was towed in from the Glen track. And that was all the Subie dealer had to know. Metallurgical defect or not it was clear right away no help would be forthcoming from this dealer. We took our plea directly to SOA in Cherry Hill, NJ. Sent pictures etc. But if you don't have dealer support, you're odds of getting help from the manufacturer go to zero. Interestingly, in 05 Subaru upgraded the STI driveline. Axles, hubs, bearings all had different part numbers. Subaru even went to wider stud spacing on the wheels in 05! My brother was a Subaru loyalist. The STI was his second WRX. And a third would have been likely. But shortly after it was fixed, he sold it and bought an Evo 9 which he still has to this day.

      The guy made it sound like the Evo that we got in the US was unveiled long before the STI. From my recollection, they were both announced at the same auto show, just a few days apart from each other in 2003. But at least the guy acknowledged that it understeers a bit more than it should.
