You think I should do that? I wasn't wanting to work on the transmission or anything just trying to change my automatic to a manual so I was trying to figure out which manual transmission would bolt up to that engine. Cuz I'm just going to put it in from the bottom as an assembly. And this project is mainly for me to teach myself for future that's why I'm doing it on an older Subaru and just trying to learn as much as I can from experienced Subaru mechanics before I jump into it. If you think turboing the naturally aspirated engine would be to big do you have a suggestion for it already turboed engine? Or should I go on like foreign engines or JDM and get a turbo 2.5?

I have rebuilt an engine for and I have some mechanical knowledge I'm just not familiar with Subarus and the compatibility between each part. I will be doing all of the labor my self. I'm trying I'm trying to figure out which manual transmission and turbo I should use with the 2.5 sohc and 2.2 heads

Well I I did not know that, but what if my goal is to turbo my 2.5 sohc? Does that open up any other options? Sorry I'm new to Subarus I appreciate all of you guys' information

Thank you a lot Idosubaru and heartless and 1 lucky texan and imdew. So if I were to get the 2.5 block brand new and put the 2.2 head on what website or where do you guys suggest I get performance parts such as, bigger cams, bigger injectors, forged pistons..etc or does the enhanced 2.5 blocks from sunwest come with all of that? Or should I still put better internals in the 2.5 enhanced block if I got one?

Thank you for your reply it was very helpful I have updated my post with some more information

I have a 1997 Subaru Impreza outback and Im wanting to swap a 2.5 DOHC engine into it. My 2 main goals are power and reliability. I was wondering if someone knew which years and models I could get one from that would require little modification. It does have EGR. Also does anyone know how to fix the "fuel temperature sensor" fault code? I've replaced the fuel pump!?!? Car will just lag out like it ran out of gas but as soon as I put it in neutral it starts right back up but it dies quite a few more times until it warms up.
