Could anyone tell me what the WRX engine turns at 60 mph in top gear?
 
Actually, both the 2.0 from previous years and the newer 2.5 would be helpful.
 
Thanks

From what I remember, my 2004 WRX turned approx. 2400 RPM at 60 in 5th. My 2006 TR is about the same. This is based on a visual of my speedo and tachometer. Obviously, not scientific.
 
Specs say the 2006 2.5 has better torque, the torque comes on sooner and there is a slight bump in hp. It certainly feels that way. Drive both, then decide.

Don't generally drive 60 mph. But in 5th gear my '02 WRX runs approx. 73-75 mph 3,000rpm. Give or take a tad for speedo error.
 
I expect 60 mph would be in neighborhood of 2500 or so.

Ah, thanks. I was just curious, doing some general research. I read an Australian review that said 100km/h was at 2800, which seemed too high for relaxed driving.
 
About 2500 for 60, or 3000 for 73-75 is about what my current car turns, and I wouldn't want anything much higher. It seems that manual transmissions turn a lot higher in top gear than autos.

I dug up an old WRX brochure that had a reprint of a Car & Driver review of a 2002 WRX. Mph/1000 rpm in each gear is as follows: 1st=5.3, 2nd=9.5, 3rd=13.5, 4th=18.9, 5th=24.9
so dop50 and I are in the ball park. This was for an American spec car. Re: the '06 Australian WRXs(100km/h =60mp), perhaps they have different gear ratios than my US model '06 TR?

Used WRX engine running rough by km24

Hi
 
I have test driven some 2004 automatic trans WRX With 15-30K on the clock and although they look great the engine seem to be louder and rougher than a new one. Are these cars suppose to get smoother or rougher with age.

The one you tested was a 2.0. The new ones are 2.5s. Sort of comparing apples to oranges...

Hi
 
They were all 2005 wrx's some with a few hundred miles and the others with 15-30k mile. One had been owned by a an older man who babied his car but the engine still felt rough and this car was at a subaru dealer. The one's with 15-30 does not seem like alot miles but the cars ran like an old car.

It's hard to say. I haven't heard of any rough older WRXs per say. Having said that, keep in mind that many of these vehicles were bought by younger guys for their high performance. So my guess is that many used WRXs out there may have lived a hard life, or at least a harder life than a non-performance Subaru.
