I have a question or two.i have a uk 2011 wrx sti 2.5 saloon,
what is the difference between the jdm version 2010 saloon and uk. Internally stronger! External aswell straight fit
and would this engine fit with no major issues from ebay item number 253563158961

Looking at the ECU info it's from a US STi Hatch MY08/09 and has been running with a decat downpipe, cold air intake and HKS SQV dump valve
you pay your money and take a chance...............

just for clarity, JJ on the ECU equates to 22611AN350(MY08) or AN351(MY09) ECUs (image looks like it ends in 350) and only fitted to US Hatches

 

I questioned him on the down pipe, intake dump valve etc standard engine internally not sure if been mapped, it's just I'm at a point on my car after the compression check 125 psi hot on all cyl and a 5 and 7% leak down decided to live with it and do timing belt but when removing avec cover on exhaust found the engine oil is glittering with metallic particals..dont know from where but only had car since November.either swap out engine or rebuild i dont want stupid power i would be happy with it running the standard 320,as a friend has one and drives unbelivabley fast and torque e. And I would be happy with the, I need help with anyone local to do it at a sensible price.
Other option do myself but don't have the time and data unless I get the CD you have don,,I could buy a ready done long block and build from there..

 

Also JDM STi hatches and Saloons are fitted with a 2.0L engine apart from the A-line saloons which has a 2.5L engine mated to an automatic gearbox.

 

So if it's a 2.5 as I've been told, the bare block and heads should fit all my ancillary's
