    We use a similar setup to your current one on our 600 autocrosser with the '07 Saturn Ecotec.
    The Saturn doesn't use a return at the fuel rail.
    In our case we are using a Summit 3 gallon aluminum race tank with connections top and bottom. We use a Walbro/MSD? 80-100 PSI pump pulling from the bottom of the tank with a carb filter ahead of the pump. The pump outlet runs back to a bypass regulator mounted directly to the top of the tank.
    The pressure line continues on to the fuel rail, no filter or gauge after the pump. It's been running for 8 autocross seasons with no problems.

    Keep forgetting to ask about this - Volvo turbo without muffler is loud except at idle - I find it hard to believe that the Fiat would be that quiet, even if the displacement is small.

    I have 3" exhaust & added cutout for when I want it loud...

    The difference I think is because of the small scroll on the Abarth engine turbo charger that spins at 230,000 RPM. If the exhaust note was loud I would deal with it because I do not like loud cars. Bob does and we may have to put speakers and an amplifier to increase the sound of the exhaust note.

    Hey Tony, what do you use to protect the bodywork? I need to tape off mine for the ensuing work.

    Well… The white as you see is a peel and stick plastic covering that I purchased a roll of many years ago to cover model helicopter rotor blades. The paper backing is fairly strong so if I am sand blasting I only peel the edge to give the plastic covering more strength.

    Years ago these peel and stick products were used to line drawers with and hardware stores sold it by the roll. The Green is 2" masking tape I purchased at an Auto Body Supply warehouse.

    Thanks Tony - vinyl shelf liner is readily available here, not expensive - I'll get some.

    Continuing on... I have been working on this as time permits, so I will post a few progress pictures.


    New fabric being installed in rear trunk.
    Module box installed.
    The electrical part of the build starts early when the harness is harvested from the car. It is at this time some major thought needs to go into what is needed and what options should be retained to the person's liking.
    Since this platform has many options, choices need to be made early in the build. It is possible to retain keyless entry, Electric door locks, cruise control and most other options on the car, or bare bones just want to have the engine run. So as for the electrics I am not going to get into a wire by wire requirement but just show what as been retained as per Bob Martin's request for his build.

    One upgrade that is required due to the fact that the battery is so far from the modules is a 1/O main power cable. Without it if the voltage at the ECU drops below 10.25 volts the engine cranking is stopped. Took a while to find that one. Symptom is a starter solenoid that keeps dropping out and chatters. On the stock X, it will crank at lower voltages than this.

    Impact sensor installed.
    Starting with the dash wiring and changes, which include installing A/C to this car.

    With some changes I managed to keep the throws short for the shifter and the stock shifter boot and opening in the centre counsel was retained.

    Still working on it.

    Impressive as always. Amazing how much time these things can take.

    Reverse engineering a modern car into a vintage one is an amazing undertaking. Not many could solve this problem. Good thing the right man is on it.

    Thanks Karl, but stupidity sometimes blinds reality. My issue... I think anything is possible with enough time and effort.

    My wife says that differently about me with some regularity.

    Occasionally it does actually work out :) even for me.

    A few more progress pictures of Bob's Build.

    Showing the clearance for the shifter rods and brake lever.

    A shot the other way with the fastening point for the cables.
    The power window plugs will be cable tied into place, I just cannot remember if the red plug goes on the left or right side of the council.
    Stock shifter boot will work nicely. Bob will cut the shifter rod to a length of his liking.

    Bob asked for a 3rd brake light for his car which did not have the wiring in this location of his 86 car. Found the light strip on ebay for $12 USD.

    A set of gauges were also part of the build.

    Just a few more wires to tack down and I will have the passenger compartment completed.
    Well all of the wiring is completed. Testing it and trouble shooting will be the next issue to resolve.

    Nice job on the gauge panel. I did something similar, but with a molded plastic panel covered with a black vinyl padding. I like yours better. Also, I put mine in place of the center vents in the console. I would like to keep a radio for awhile but maybe if I'm going for something more modern smaller module(Bluetooth / MP3), that would be an option. Anyway, the gauges are there but I didn't hooked them yet! :oops:
