What do you mean when you say "because of the torque the NA 2.5 has" ?

 

Low end torque that i'm not used to, after driving a low-compression turbo car for the last four years. Compared to an 8:1 compression 2.2, a 10:1 compression 2.5 can crawl around much easier at low rpms.

 

So you're saying that it is easier to drive slow speeds in a N/A compared to a turbo. I drove a ForesterXT a few times and it feels like it crawls a lower speeds the same as my N/A

 

You have to ride the clutch a little at slow speeds, otherwise the torque of the engine will just make the car shudder like that. It's much worse when the car is new. After a year though it feels better but not totally gone. This is why I hate driving stick in traffic

 

I think the LACK of torque is what makes the jerkiness. Turbo cars have low compression w/o boost...so in 1st, when you're barely going, you have very little power and very little torque. This means that:
"On acceleration, it almost like there's a slight hesistation just after pressing (slightly) on the pedal, then it jerks forward to pick up some speed. [Because there's not enough torque to just move the car smooth]. On deceleration, it's like the car wants to stop moving or like the engine wants to stop, but the inertia of the car won't let it, which makes the car buck. You have to remember, this is while still rolling at a low speed, probably in the range of around 5-15mph." _051

All stock WRXs have that problem, and I'm sure just about every turbo Legacy does too. I've gotten better at making it not jerk, but mostly I just wait until the guy in front of me is far enough away that I can make a good normal start.

 

Yea, my n/a forester is a few months old and the bucking/jerkyness in 1st is pretty severe. I have also gotten used to it and can smooth it out as much as possible but it can be annoying for my passengers at times...

 

I deal with a stop and go rush hour every day, and my brand new 2.5 RS wagon does the same thing. It gets really jerky when I'm off the throttle in first in heavy traffic. It is worst when the car in front of me gets moving a bit after a stop then immediately hits the brakes again before I get enough speed to make shifting into second worhwhile. I just try to keep plenty of space in front of me and roll at low speed in second as much as possible.

 

My 2.5rs jerks badly when going slowly. You pretty much have to ride the clutch , it sucks.

 

I agree...my wrx is a problem...my friends STi is smooth like butter

 

my03 RS does the same thing at low speeds. esp in traffic. I think this is a common symtom for some subarus.

 

My '97 legacy wagon jerks after it rains outside. You have to ride the clutch for the first few stops, and then it smooths out. There seems to be no ryme or reason why it happens though.
