    Hear me out...

    I could try to go down the Trev route and mod/hot rod my 360 Modena but in 2025 nearly every part is NLA and almost impossible to find. It would also cost an arm and a leg.

    OR...

    I can purchase a very sweet Challenge car that recently popped up that has everything I want and is owned by a collector that restored it.

    So, what challenges (pun intended) will I have going into this?

    Open questions I have are:
    1. Can the suspension accommodate being raised to CS height without messing up the geometry and risking bump steer?
    2. I read somewhere the uprights are the same and I can swap for Modena uprights to get the parking brake working, does that sound right?
    3. Can I get this to work with 91 pump gas?
    4. What does one need to do to allow the pump nozzle to work with the dry breaks?
    5. Can I fully remove the cage or just leave the rear hoop? Obviously there would be a gap in the dash but not horribly keen on running a cage on the street. Door impact is a concern but I'll figure out something for that.
    6. How difficult would it be to add a heat exchanger to speed up warming engine/gearbox?
    7. To take this to an absurd level, if I have stock cats and a title from another state, could I go through the G&K process and get this registered in CA? No SAI or EGR would be the only thing that I could think of that would be a problem.
    8. What do I do about lack of keys/locking the car?

    Other thoughts:
    • To my understanding, there's ways to get this titled in certain states (e.g. Dirt Legal). Let me know if that is going to be more difficult than they make it sound.
    • The car has motons so I'd want to get those revalved and replace the springs
    • I have two 360s to borrow parts from to make the above happen so I can swap as many parts as needed to get it through compliance processes
    • I expect this won't be cheap and there's more sensible things to do with my money BUT...I like having unique things even if they make zero sense. This will likely be a lot cheaper than the air cooled, hot rodded minimalist Porsche I tried to buy today on BAT.

    I’ve been wanting to do this for years.

    the big hurdle may be registering it for street use with the challenge vin

    I was going to buy a wrecked Modena for that purpose and make a super lightweight outlaw street challenge car.

    gl!
