Hi guys,
I have done a fair bit of research, but wanted to make sure I'm not overlooking anything before I move forward with my plan. I have a 1998 Outback (EJ25D) with an Auto transmission which has some severe rod knocking. I also have a donor vehicle (2001 Outback), with a good motor. I was going to keep the EJ25D head and pull the EJ251 block into my car. This is all just for a daily driver / road-trips.
It looked like I could swap the block into my vehicle with no issues. Here are my questions:
1. What headgasket should I use? I had read conflicting posts, but it sounded like the EJ25D HG was the safest bet.
2. Do I need to swap the crank sprocket from the EJ25D onto the EJ251? Someone mentioned that the crankshaft position sensor may be an issue?
3. Is there ANYTHING else that needs to be addressed to do this swap?
I couldn't find any guides on how to do this particular swap, but from what I read, it seems straightforward.
Thanks!
