slonez Posted July 14, 2010 Share Posted July 14, 2010 Hi, I am not familiar with Subaru powerplant/transmission, please bear with me. Just checking what's the difference between the 2.5 & 2.0 transmission other than the SI drive? Which is more responsive for aggressive driving like going on tracks? Which one more problematic? What is the maximum power/torque for both the transmission? Many thanks! Link to comment Share on other sites More sharing options...
fishbone Posted July 14, 2010 Share Posted July 14, 2010 What 2.0 are you talking about? Link to comment Share on other sites More sharing options...
slonez Posted July 14, 2010 Author Share Posted July 14, 2010 Hi, Over here in my country, the LGT are 2.0 up to 2006 & 2.5 from 2007 onwards. The 2.0 also on 5 speed auto but without SI Drive. Basically I would like to find out the difference in mod potential, reliability & responsiveness during hard driving. Any info is appreciated.

fishbone Posted July 14, 2010 Share Posted July 14, 2010 As far as I know Subaru isn't terribly diverse when it comes to transmissions, meaning that their 5EAT is most likely the same on the 2.0 and 2.5. That being the case, I think you will be happier with the 2.5 because you have SI Drive and half liter of extra displacement, which does make a difference. Nobody knows for sure what max power the transmissions can handle but typically Stage 2 seems to work great. Just make sure to get at least a decent transmission cooler and replace the transmission fluid on a shorter schedule than what the manufacturer recommends (20K miles/32K km is a good point) if you drive it hard.
