    Arrival Resized.jpg Thank you to everyone for welcoming to the group. I don't really plan on doing one of those build videos that show me taking off every nut and bolt but I will post photos now and then to update the group. Please ask me questions and I will try to answer them. I will also feel free to ask the group questions too. Here is the car when it followed me home.


    Stripped Resized.jpg
    Here the car is stripped and almost ready for the cage. I still need to do some seam welding, remove the stock seat mounts and cover floor holes. I am hoping to have to RallyWorX in April for the cage and powder coating. Then I get to convert it to an AWD 2.5 RS.

    The plan is to run the car in the non-turbo 4wd class with my daughter.
    The current plan for the car includes: 2.5 Motor and 5 spd manual trans from a 99 Forester.
    The Trans will have a 20Kg Center Diff with LS front and rear diffs.
    The suspension will be DMS rally Suspension. The engine will be refreshed by RallyWorX and include Delta 3000 cams.
    Together with the Cold Air intake, wide open exhaust and reflashed ECU. Any guesses as to what HP that should generate?

    190-210 awhp? I’m probably on the high side of the numbers? I can’t recall what they put down stock

    Looks like 165 crank HP stock. https://en.wikipedia.org/wiki/Subaru_Forester#US

    Some back-of-the-envelope calcuations:
    Assuming you can pull another 18% power from your modifications and accounting for 20% drivetrain loss, that puts you at about 156 WHP?

    Stock pistons and compression ratio? What gas?

    Depending on the dyno, I'd say 200whp and 175wtq give or take assuming e98, aggressive tune, and that the same engine with the same trans/tires on the same dyno on the same day with the same dyno settings makes around 125whp/115wtq.

    Also, welcome and good luck with the build and race season!

    I'm guessing 175awhp

    Careful with the CAI on a rally car, as you want to keep it protected from the water/dust. Also you'll need to run a cat and muffler to pass any rally inspections.


    What events do you plan to run?

    Do you need a 2.5RS donor?

    I suspect that Steve knows these things, having been a national & club champion, and RA Steward for several years ;)

    The Rally Impreza is now back caged and powder coated! Now the hard work begins.
    However, I made a huge rookie mistake by not taking lots of pictures of the car before I took it all apart. Caged and Powder Coated - Resized.jpg
