Default hybrid question

ive been doing alot of reading on building a hybrid for my bugeye since my stock motor just grenaded.. im looking to do a 2.5 with my 2.0 heads (granted there not destroyed).. i see everyone talking about using a ej255 or ej257 bottom end to do this.. could the same be done using a N/A 2.5 bottom end? i plan to swap out pistons and possibly rods no matter what and i can get a N/A 2.5 for pretty cheap.. i couldnt find anything saying yes or no so i figured id ask, please dont flame me

and im aware of everything else needed when doing the swap just need this info


and its going into an 02 wrx if it matters

I have an 02 with a 2.5 bottom end. I purchased the car this way and didn't find out until months later. I would stay away from N/A motors because the block is not reenforced. Make sure you have a way to tune the setup once the wrenching is done. My car was missing the AP when I pulled it out of a junk yard.
