Default EJ25dz build

So, I am considering parking my car for a little bit or buying an engine from a wrecked 97 or up impreza/legacy. I can have T sleeves at local machine shop put in but the main question is will an sti crank assembly and heads bolt up to the block.. I can get most of my other parts such as turbo injectors possibly rods n pistons and a few other pieces from my buddy who is doing a 42R build on his 04. Any other tips would b great.

they will physically bolt up. You need to make sure you have a machine shop machine out the #5 for the phase2 thrust bearing. This will allow you to use the phase2 STi crank "correctly." When using STi crank, you have to purchase rods and pistons made for STi.

EJ25DZ..... I have never heard of that engine before.... please be specific to reduce confusion.

EJ25DZ is in the 97-98 imrezas and legacy's. To my understanding almost all 2.5 blocks are the same minus the decks on the turbo engines. Thats why i was considering the t sleeves due to the open deck on my engine in the rs and those years.

What do you mean machine out the #5 for the STI crank? If i get the crank asembly it will be rods pistons the whole rotating assemly.

I was under the assumption this was is a 2nd revision phase1 EJ25D, which is it, thanks!
Phase1 thrust bearing is on main bearing #3, phase2 thrust bearing is on main bearing #5.
