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 am still confused...
The US WRX STI motor is not the same as the JDM WRX STI motor? Explain the differences once again between the 2.0 WRX motor and the STI motor... What is a semi closed deck? is the head difference or is the case closed off somehow? Rich |

I can't give you specifics though... but I believe that the JDM STi is still 2.0 liters. The standard Subie engine has cylinders that are free-standing in the water jacket (open deck). The semi-closed deck on the STi has webs that support the cylinders. I found a pic: http://www.grindstonemotorsports.com/tech/blockdesign.jpg |

So, which motor has the closed deck...its the one I want. And... What is the base HP for these motors? I dont want to re-invent the wheel. A US spec wrx turbo sounds like the place to start if I want to get into the super tuning level of fun... Rich |
