Default 04 XT motor in 05 STI?

So I tried to find an answer some where else but its hard to type in the keywords without google pulling up just people sti swapping a fozzy as opposed to my situation, which would be the other way around.
Basically I need to pull my motor due to compression and a buddy of mine offered me a good price on an 04 xt motor and he said hed do the swap.
Will this work as a direct swap, and what parts are different is what I really need to know.
And will the Cobb AP and the ECU in the car work the same with the fozzy motor?
This is my first time posting to a forum for help but I couldn't find enough research to back up going through with it or just trying to see what i can afford to rebuild or something.

the longblock is exactly the same


everything bolted to the long block is different including the coolant crossover pipe

(the tgv's , injectors , fuel rails are the same , intake although silver is ALMOST the same with a different vacuum nipple here or there )

... in other words, this "good deal" is not a good deal.

I donít agree.

Iíve done multiple swaps moving parts around to make it work mixing and matching ej257 heads with ej255 shortblocks. The peripheral stuff is exactly that and can move from one motor to another. One example was a complete 06sti motor bolted directly into my 05fxt and fired right up with the factory ecu, accessport and all. Take a look at what youíre working with and make an educated decision. Even though some parts like the crossover pipe might be different the outlet location may be close enough.


Good luck!

Ok.. Iíll digress to some degree. If the guy said heíll make it work and is making himself responsible, then go for it. I think youíd better have a prepared mindset though. There may be roadblocks and complications. It make take much longer and cost more. And the car may run differently than youíd expect. Hopefully he fully knows what heís doing.

I appreciate the info from everyone, I think Ill have him go ahead and do it. The guy and all of his brothers have lots of experience with motor swaps, I know he has a Datsun with an RB he put in so I trust him for this swap, he wants to do it so I know he'd take care of it
