89xt Posted March 2, 2013 Share Posted March 2, 2013 I want to know if this is possible, and if so, the procedure to do it. I have a 2000 OB LTD Sedan with a normally aspirated 2,5 SOHC engine. I saw a 2002 WRX 4DR Sedan with engine problems. It may just need heads, but I would like to know if it is feasible/reasonable to take my engine from the OB Sedan and replace the turbo engine. I've read about this, but I have never done it. What EXACTLY will I have to do? Thanks. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 2, 2013 Share Posted March 2, 2013 your wording makes it confusing...i can read it two ways - you're trying to pull the OB engine into the WRX or the WRX engine into the OB? Quote Link to comment Share on other sites More sharing options...
89xt Posted March 3, 2013 Author Share Posted March 3, 2013 GG-I'm trying to take the 2.5 from my OB and put it into the WRX. Sorry for the confusion. ED A Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted March 3, 2013 Share Posted March 3, 2013 To do this you would also have to deal with differences in wiring and the ECU, which may require tweaking or swapping of the electrical harnesses. Unless you are very set on this, I'd probably suggest against doing this as it'll likely be quite a bit of work and other electrical issues.

Numbchux Posted March 4, 2013 Share Posted March 4, 2013 It would either require extensive wiring modification to use the OB ECU and harness in the WRX, or a GD Impreza 2.5RS harness.... I, too, would recommend against it. Quote Link to comment Share on other sites More sharing options...
