2.5 to 3.3 in an outback, how hard would it be?

Featured Replies

since i need a completely new motor for my 99 outback, how hard would it be to stick a 3.3 under the hood? anyone ever done the conversion?

 

i know i'd need a complete 3.3 harness and ecm.. maybe an intrument cluster as well.. otherwise i'd imagine everthing else would be the same sicne they do make an outback with a 3.3..

 

any feedback on this?

I don't think it would fit.

 

3.3 = SVX engine 3.0 = new 6 cyl.

 

You're thinking of the 3.0 in the second gen outbacks (third gen legacies)... that one *might* fit, but I don't think the SVX engine would fit... too big. There's a guy on Nasioc that has a 3.0 in a mid 90's Impreza... they actually have a lot of stuff written up on that install, and it took a whole lotta work. Barely fit in there. Here's the FAQ about the swap, interesting stuff:
