03 wrx full engine swap to 07 sti

I have an 03 wrx that has all bent valves and engine is junk. I am buying an 07 sti engine complete with 60k on it.

I will say this now... I am somewhat new to the Subaru world but not to the wrenching/swapping/customizing world...

So I'm curious to those who have knowledge of this kind of swap, what am I going to need to do this swap, will it fit, motor mounts the same?? Will it bolt up to the 2.0 tranny or should I straight look for an sti tranny?

Looking for insight and knowledge from experienced people!!

Thanks in advance!!

Everything is the same except some sensors, the throttle assembly (intake manifold, throttle body, pedals), the wiring harness, and the ECU.

That's good to hear! Even the tranny bolts right up? I heard something about having to splice into the stock wrx harness to hook up the sti ecu and such...
