Car Info: 2004 WRX STi
The EVO is a very fast machine and the STi will have it's work cut out for it. I'm glad to see that its doing so well stock. The compitition can only make both cars better. There was one post on evolutionm.net claiming 13.1x in the 1/4 mile (have not posted slip yet). Man that's fast for stock. The EVO is strong but you gotta to give the driver props for that one though, the guy's been drag racing for 19 years. Someone else posted on the other Impreza board that he saw a bunch of EVO at the strip and none could break into the 13's. There is something to be said about having good tools for the job. There is more to be said about being able to properly use said tool.

MAN, that is the dumbest thing I have ever heard, the engine has been around for almost 15years. and it can take 45psi without any problem. check out JUNUSA. can you say over 500 hp to the wheels. try burning all 4 tires in 3rd gear. that engine will never die. as for the subaru. It will be as difficult to tune as the 2.5 rs has been.
You are correct about the 4g63 being a strong stock engine. I have no doubt that it will stand the test of time. As you have stated it has been around for a long time making big power. It is capable of big power. It can take 45psi and JUNUSA does have a 500+whp machine, but not on stock internal. The stock parts will probably be able to take on most bolted on mod and make big power. But monster power as always will probably require a full build.

Actually your comment is pretty uninformed. First there is no way in hell the 2.0 will handle the power your talking about with out changing all the internals. At least the sti comes with forged pistons. The 2.0 comes with cast iron pistons. The evo 2.0 engine will only run about 360 to 370 hp with out needing to change the internals. And your not going to run much higher than 19.5 with out changing the internals as well. The sti motor is not the 2.5 rs motor. This motor has been completely reworked. The internals are not even close to being the same. The only thing these two motors share is the 2.5 designation. You need to do a little research before you go spatting out nonsense.

That's fine if the subaru engine "has yet to prove itself" but don't call it weak. There is no evidence what so ever that it is weak. In fact some of the features of this engine are:

1. a specifically reinforced Semi closed block
2. Forged Alluminum alloy pistons
3. Forged high-carbon steel connecting Rods.
4. Sodium filled exhaust valves.

Doesn't sound weak to me.

Max boost also comes at a really low rpm

By the way the new sti motor also has only 2 cats. There is no cat on the uppipe.

Agreed, but I've got a question. I don't follow Mitsubishi that much so I'm not sure about this. Have that got that crank walk issue fixed? I know lots of people in second Gen Eclipses that have had this problem and destroyed motors.
the crank walk issue was never officially admitted by mits so I doubt you can find a reasonable answer to this. Most will say that its not an issue. And so will mits lol.

well, speed can be used in many ways, but for the STi as well as other AWD cars, i would be more concerned about the handling. what good is speed if the car can't handle that speed. yes it is possible to take a turn at a high speed, but there's only so much that physics will allow before either spinning out or losing control. good brakes also help in gaining that much more on your opponent when you can brake later and accelerate faster. and probably the most important you'd want a good pair of shoes to go with it. i would say how quickly your car can accelerate out the turn is more important than having it go 11 or 12 seconds. now on rally courses (mud, snow, etc.) i think speed is out of the question. it all depends.

To quote Shiv who has driven the sti. Nothing short of a porsche 911 launches out of a curve like the sti does
