I'm unfortunately in need of a new shortblock and I've been attempting to understand the similarities and differences between the 255 and the 257 but I'm still a bit unclear and was hoping one of you gurus could give me some advice.

My car ('05 LGT 5mt) is currently unmodified and I have no intentions of doing anything major in the future so I'm guessing that replacing my shortblock with another exactly like it would be just fine for me but if I have the opportunity to upgrade for little or no added cost then naturally I want to do that. I guess my question is quite simple: what is the best shortblock for me to buy and run using the stock tune and hardware?

I can buy at wholesale through my local dealer but just for my own reference I was looking at and I see different part numbers for 04-06 Legacy, 07-09 Legacy, 07 STi, 08-13 STi and so on.

Your knowledge and assistance are deeply appreciated.
