So, whats the list of decent motors for a subaru swap?
What is the price range nowadays? If going down this road...is there a motor that can be upgraded to the STI motor over time??? Ideally I would like to figure out if a 2.5 liter legacy motor (or whatever) can have new cams and special head work and become an STI...etc... Rich |

I just remembered another consideration... the STi (and maybe some other newer cars) are drive-by-wire, which can be a PITA to adapt.

Those are all after 2005, so stay with the older engines and you're fine. But even if you get a new engine you can just put on an earlier mechanical throttle body with a standalone ECU and you're good. Then there's variable valve timing starting in about 2004 (depends on which engine) which is on-off, so easy to control with an aftermarket ECU. More complicated is variable lift (starting in 2006, also depending on which engine) which isn't linear and depends on a lot of different engine operating parameters. Evidently an upcoming version of the Link G3 ECU (in the next 60 days or so) will control that as well, but for right now you won't get the extra torque that the variable lift gives under 4000 RPM. Those aren't really big obstacles though. If you get a chance at a reasonably priced and nearly new STI engine I'd grab it and gladly deal with the newer technology. In the meantime a nice WRX motor and a Renegade kit would give you all the thrills you're likely to need. |
