We'll it happened. I spun a rod bearing and warranty won't cover it. So I have a plan to swap a 2011 sti(ej257) engine in my 2011 Wrx(ej255) one thing is will I need a Sti Ecu or can my wrx ecu work? Also what about the harness on the Sti engine, will it plug right in or will I need to do some modifications? That's all I need to know. Thank you.

I would assume since the STI has avcs on both intake and exhaust cams while the WRX only has it on one cam, that the wiring is different. The ecu probably will not plug right in either.

You could get service manuals for both cars on eBay and compare the schematics.

If you find out that the wiring is different, yes.

I just purchased a 2008 impreza and would like to swap either a ej255 or ej257 into it. Don't know where to start other than buying the block...

Ok...I must be missing something. I can't seem to find any info on Phase II swaps. I'm working on dropping a 2.2L Impreza A/T in place of a 2.5L Legacy L M/T. Not finding much.

On ly side, i just bought an engine from 08+Sti Ej25, i'm using Motec M800 with cable throttlebody, car is starting well with 0.6boost, but flutters after 6krpm, one of the AVCS is missing ... I'm trying to find if it is AVCS related, or tuning problem, if i stay under 0.8bar boost, car is doing fine, above that it's anyone's guess... Any help guys?

It sounds like your throttle cable is too tight you might want to check that.

My04 Wrx has been running a Wrx ECU and engine harness an an 05 sti longblock with top feeds and Wrx mani and cable tb. I want to set it up more correctly since its apart right now for some front end work. What engine harness, ECU, and etc. do I need to run this either with an sti ECU, for avcs, or stand alone. I'm real curious as with my Wrx tgvs intake mani and top feeds with 800cc inj what I can do to clean the setup a bit and make it more 'correct'. Thanks.

Also, should I source a jdm sti engine harness and ECU? And if so which ver should I try to source? And my 16bit USDM ej20 is running this all.
