You get those Diesels tuned right and they can deadset pull like a V8 - bloody amazing performance from a 2lt size diesel motor.

Yeah I don't know what they did to my mates subbie, my BT didn't really have the boost altered much at all if at all, it was more altering of the parameters of when the boost happened and also changed the torque settings on the auto so the torque cut in earlier type thing, all I can say its a big improvement on how it was to what it is now and no real increase in fuel consumption either which is great.

ECU tune and 3" TBE really made it come alive instead of that asthmatic example it was (smashed a V8 Landcruiser going up a mountain the other day, he was trying but had nothing on the BT :lol:

Did that cure the shocking lag from hitting the accelerator to actually moving?

I looked at them in 2007 and decided the lag made them too dangerous to drive. I checked both 4 & 6 cylinder, it was part of their drive by wire nonsense. It was reminiscent of a 1.2litre corolla I had in the late 80's, making the car gutless and unresponsive, just what you don't need when a semi comes around the corner after you already started pulling out of a side street.

Nope she's still got serious lag issues :thumbsup: I reckon if he had the ECU tuned it could be removed or improved. Other than that lag issue its a beautiful car to drive, they go seriously hard when tuned and bigger exhaust to let em breath.

Hmmm... I had a 2009 I think it was forester as a loan car and the throttle response was pretty good.

Wonder if you guys got issues or if I got the lucky one?

Hard to say mate, all I know is if you stomped on the accelerator it would take a few seconds to really respond, but when it did man did it come on hard and strong (V8 like performance).

Unless you're willing to spend the extra on putting a chip in the diesel, I'd go for the petrol motor and leave it standard. Diesels are great, I have one in my Pajero, but you have to be careful with service costs. They can get a bit steep. I'm not sure who makes the diesel engine in the Subaru though, as far as I know they have never been involved in diesels.

It was a deal breaker for me, bought the missus a 6cyl Mitsubishi Outlander instead.
My opinion is a delay in acceleration is nearly as bad as a delay in braking, when the unexpected happens you want it to work instantly.
Seemed to be plenty of grunt in the 6cyl subaru I test drove as mentioned above, but without an actual throttle cable.. bleh. There were different modes in various models from memory, maybe one of the full sports tunings would have behaved better.

I thought they made their own, but they're a recent foray for them. I think it was about 2008 they added diesel engine options to a few of their line-ups?

In general Subaru seem to make a pretty good engine, and the diesel should be no different. A few years to see how they last over the long haul will tell.
