Impreza engine

If they are both 4 cylinder engines then the size may be different you didn't put what size it is. If you are thinking of replacing the one with theother make sure to match everything up except for dress like alternator, etc and use your current ones.

You would be better off going on the web and finding most of theinfo you can about that. There are a few 4 cylinder engines for 2008 depending on whether or not the model of the CAR is a 9.3 or 9.5 etc, Not the model of the engine. We do not list a impreza engine as we deal with repairs mostly. Like I said you 'll have to match things up like measure mounting bolts, etc then use the stuff on the 2005 on the 2008 engine which would inclufde the computer.

Ok after looking further, the 9.5 has a 2.5L engine in it, butit is dual overhead cam and our s is single overhead. The 2008 also may include cam fazers which yours may not have and your computer would not be able to handle teh dual fazers as it's not set up to operate them. Why not just rebuild yours. Even if teh block has a hole in one of the cylinders you can sleeve the cylinder and it's like a new engine. Either that or see if GM parts direct carries that engine an dyou can get that. It would be the same motor with no dress items, alternator, etc. PLus it's brand new.

The 2005 suba engine is the same as the 2005 saab 9-2x engine u cannot use a 2008 in a 2005 sorry, as was said to u before just rebuild your current engine cheaper & very easy to do. Good luck.
