View Full Version : I have an 07 impreza 2.5i engine interchange

Hello, will a 2007 Legacy 2.5 (non turbo) engine work in my 2007 Impreza 2.5i? If so, what parts would I need to change over? Are the heads different? I have rod bearing noise at 63,000 miles. SOA will not goodwill the repairs so I'm kind of on my own here. Can anyone help me?

Oh, I almost forgot. Currently own 93 Legacy L+ sedan, 05 Legacy 2.5i sedan, 07 Impreza 2.5i sedan.

The swap should be pretty much the same just check as you go. The intake may have some difference but thats easy to change over. Both should be VVT so the heads etc. will be the same. One thing to mention is they arent uncommon for piston slap if your not getting them mixed up. If that is your problem its not too too bad to just replace the pistons.
