Christmas in April, Subaru 2.5 NA SOHC 2003 Impreza TS with 5MT Transmission Options

[R_u_dd]

After long deliberation and a lot of research on my Subaru Conversion, I received this engine transmission combination in the mail from Alberta, BC. It's a Naturally aspirated SOHC Subaru 2.5 litre out of an Impreza TS (2003) with 118K miles. I was able to get the transmission and ecu from the same car. The tranny is a 5mt with hydraulic clutch.

I tried the donor car approach on Copart and kept getting outbid for what I wanted to pay. In the end I went direct on ebay so I could get the exact engine year I wanted and I did not have a hulk sitting in the driveway for the neighbors to look at. I paid more than I wanted ($1,574 with shipping) to but in the end , you get what you pay for.

The plan is to change the head gaskets, check the condition of the clutch, and convert the transmission to front wheel drive. Any other suggestions on the engine? Anyone know it that's a push or pull style clutch? Looks like a push from the photo.

Ian, I will be needing your help once you are up and running.

The cable setup that jrust and rnellums have is really pretty slick and requires less fab work than the hydraulic setup, but if you're already halfway there... Another idea since you're replacing the head gaskets is to tear the heads down and do a little good ol' fashioned porting work. Port matching, unshrouding valve pockets and removing unneeded casting flashing all adds up to one of the cheapest bang for buck mods you can do, especially since you're over half way there. Shop around the good engine shops for price or maybe a talented friend who gets really thirsty now and then. Worth the effort in my mind!

Thanks for the advice. I am guessing that porting increases airflow and horsepower. How much is the question? Might as well put some headers on as well.
