A good read on the inherent strengths and weaknesses of the Subaru EJ motor
 

Found this on the WRX Facebook group and I think it'd a good article for this new to WRX's and tuning and who want to increase their knowledge. (knowledge is power!)

Disclaimer : it's American so there's plenty of self promotion.

A mate sent me a link to this today and had a few peeks at work. Looks like they're mostly referring to the 2.5, although I might not have gotten far enough into it yet.

If i had to boil it down, it really suggests that the "tuner" is key.

That record seems to be only listed on the AMR website and not in any records anywhere else, it's also a 2008 STi according to them, as well as being a registered NHRA drag car...also there is no evidence of the said 175mph and 7.75seconds...
Here read on, around page 9 they claim the performance just jumped from a 10.54 at 142mph to the said 7 seconds and then its naisoc popcorn :happy1: time:
