    Hi all,

    Lot of small things to update on, some since the last post and other small things that we never posted.

    I'm MasterC17's younger brother, we have both been building the car together over the last 9 months. I have wanted to rebuild this car for the last 6 years, so exciting to see it nearly finished.


    1. Fire Suppression System

    First big item is the Fire Suppression System from Lifeline. Went With Mechanical 2020 System.

    I've never installed a system like this so I was just doing what seemed best but im sure it could be done better.

    Just noticed the line got pushed down in the bottom left of this picture, ill fix that!

    The last things I need to do on this is potentially add the aluminum Nozzle mounts to the passenger side engine nozzle, and the interior nozzles. They seem very sturdy as is, not sure how crucial this actually is.
    Then I need to do a final mounting location for the mechanical pulls to activate system. Plan is to build mounts and weld into the cage.

    Overall pretty happy with how it came out considering I didn't really know what I was doing.

    We chose to mount the bottle in the trunk to keep it out of the way and shift a bit of weight to the rear. We plan on adding a passenger seat in the future.


    2. AIM MXG Dash Logger

    The next big change was to upgrade to an AIM MXG. Got a good deal buying almost everything used. This is the Strada , but we bought the logger accessory.

    Along with this we installed a cluster delete panel and light switch delete panel. Came out clean.

    Didn't take any great pictures of it, but here it is with the delete panels. Note that I painted the tear in the seat with black paint, a lot less noticeable now. This seat will get replaced at some point, but not a priority right now.

    You can also see the eyelets for the anti sub portion of the 6 point harness. Previously this was wrapped which I wasn't super comfortable with.



    3. Brake Lights and Turn Signals

    The last big change was to wire up the brake lights and turn signals. The reason for turn signals is that we plan to break in the motor on the street..... That may go poorly but im willing to see how it goes lol. Wanted to be as legal as possible even though the car will never be street legal again.

    No pictures of the front but that's just a ground and power tapping into the same wire as the rears.

    To operate we just have a simple switch that I mounted on the Dash.

    Here I realized I didn't take the Trim into account which was a bummer lol. Ended up Cutting the trim, removing the bridge between the trim. Not supper happy with it as now the start button portion of the trim is a bit flimsy. Ill figure a better solution out later.


    Along the way there was lots of small things done but I wont bore with every detail. The car is effectively complete until everything breaks and we have to fix it lol.

    I will follow this post up with some semi final pictures of the car. Really happy with the results.

I just used a crimp on ring terminal and put it between the sensor and the fitting. Then used one of the thermostat bolts on top of the lift bracket as a ground.

    Fvcking VAC!!! lol
    I was able to get the pin out and fortunately this one is grounded to the AIM!

    Appreciate all your help through this build!

    BTW...your valve cover is dirty! haha

    Are planning to reinstall the dash and/or use the OE instrument cluster?
    Haha yeah I'll have to make it look prettier at some point!

    Dash will be going back in, and just using the AIM MXL Pista for now (old school I know).

    It runs! Took a bit of an effort, but we were able to start the motor today. Other than one noisy pulley it sounds great!

    Still many details to get sorted out before an event, but massive progress from six months ago.

    There is a lead that goes from the hall effect switch to the DME which I am assuming activates the lead going to the solenoid. Not sure if it makes a difference, I have an LCI with the LED tail lights as well.

    And I had a push button switch in place of the hall effect sensor. I wasn't confident in the reliability of the push button either.

    Agreed - I don't remember exactly what I did, to be fair, but I removed the LCM back in 2013 and ran that way for two years without any issues.
