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.

Ok, rumor has it that the STi will run mid 13's stock. That coupled to the fact that the car onyl runs 14.5lbs of boost stock should make it fairly easy to get into the high 11's.
The comment about the Subaru motor from 2004STi doesn't even deserve a resopnse, but I will say this. I'm glad to see that you know this brand new 2.5 motor our US STi is getting will be as hard to tune as a 2.5RS motor. Since you know this you must be one of the engineers that designed it, right? Or now wait, you own a tuning company and have one right now that you are working with?

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.
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.

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.

ohhh one more thing. why are you so worried about being faster? Mid 13's is really fast compared to most vehicles and to be in the 12's is really really fast. If all you care about is straight line speed then the STi is the wrong choice. You'd be better off with a Supra, '03 Cobra, or Corvette.
Just remember, no matter what you put on your car...there will always be someone that's faster.

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.

Crankwalk was mostly found in 95-99 DSMs. These motors were 7 bolt instead of the previous 6 bolt motor ( pre 95). There was no found rhyme or reason behind this. There were many theories but none were found to hold water fully. Crankwalk happened more on the 97-99 motors than it did the 95-96. The odds of the EVO havng a chronic crankwalk problem are small. This is because they did little to change the EVO motor from the past few years and the previous EVO's have had no problems with it. Saying that its not possible because they are new cars isnt true at all......there were reported cases of crankwalk on 99 GSXs with less then 30,000 miles. The reason the problem was never solved (i.e. a recall) is because the cost for Mitsu would have been more (new motors for 10's of thousands of cars) than dealing with the few lawsuits they faced on account of not fixing it. If the motor went and the car was under warranty however there was nothing they could do but fix it unless they could pawn it off on the car being modified. Hope this helped.

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
