07 STI Longblock into 06 WRX
This is a thread to help any wrx owners that have blown their motors and can only find sti ones forsale. This is done on two euro/ Australian long blocks. So you may find further differences with the cam pickups on USDM versions.
No need to comment yet i will add to this post over the weekend while i am doing the install Basically unless you want to do a heap of wire tracing/ rewiring, the wrx loom needs to be used it has 2 section. The STi has only 1 section which goes to a huge plug. Differences
Both motors are now side by side. it took 3 hours to remove the motor Basically swap the tgv sections over and its good to go, the motors are very similar in almost every way. The intake manifold comes off easier removing the lower and upper parts with the turbo intake instead of trying to undo the fuel lines seems to be no wiring needed for this swap at all, great news motor its in and running much quieter then the tired 06 motor. Pretty much a easy conversion if you have both motors side by side.

bringing this thread back to life, I am building a block for my 06 wrx and am trying to find heads to use. Looking at b25 ones but am unsure it they work. From what you said here it worked out right? no problems with sensors or anything?

I have a 2007 WRX TR with slight knock and need to swap the engine out. So basically the STI long block is a direct replacement with the mentioned modifications? I am looking at buying a STI swap and was wondering if there were any other issues with the swap?
