  • I knocked out a bunch of the little stuff on the list, and some of the things that had me a bit frustrated as well.

    one of the big (ish) items I was able to accomplish was getting a dipstick fitted to the engine, which actually worked out to be much easier than I expected.

    the 3900 dipstick tube fits the earlier engines, but the tube is longer, thankfully, the 3900 dipstick is longer by the same amount, and the 3900 dipstick sticks out of the end of the tube by the same amount as the early dipstick sticks out of the early tube. Therefore, if you install the 3900 dipstick and tube in a earlier engine, it should fit and read exactly as the early dipstick and tube.

    As an added bonus, the arrangement of the 3900 tube puts the tube further away from the head, so it will probably clear most header flanges. it touches my 1/2" flanges, but I suspect it would clear 3/8" it's also in a position that clears my coils! all around, epic win!



    In other news, I marked TDC on the balancer and timing cover, once I have the engine back in the car, I'll turn it over and shoot it with a timing light to determine the 24x wheel sensor offset so that anyone else doing a similar swap with a MS3 based ecu can use the internal wheel easier.

    I also got the plenum port matched to the lower, painted the alternator and tensioner brackets, and tightened the engine mount bolts up. hopefully tomorrow when I get off work my level sender and fuel pump will be here and I can install them, if that goes smoothly, I might start on the charge pipe and getting the engine back in the car.

    Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.

    I get bummed out every time I type "titties" in the search bar and nothing pops up....

    Built not bought, because bolt-ons don't...

    • Fuel system parts came in, so I got to work on it, the new sender was almost a perfect match compared to stock... except mirriored... DOH! I was hoping to just bolt it to the stock resistor housing, but it wouldn't be that easy. instead, I bent the travel stops on the stock sender 180 degrees, and tacked the new sender's travel stops to the old sender. then bent the new float to the proper position. A possible important not that I had never noticed about the stock fiero sending unit, is that the pressure line at the pump hookup is necked down to probably 5/16" or 1/4", way smaller than the rest of the fuel line. I cut this off, and attached the new PTFE discharge hose where the tube was a full 3/8".







      All I'm waiting on now is a wire bulkhead fitting to pass the wires though, now there won't be any splices in the tank.

      Other than that, I got a good start on the charge pipe, I have enough material to make another, and I'm not too happy with how the welds turned out, so I might just redo it (I have about 20 minutes in this one) to finish it, I'll have to add the maf sensor mount, and the BOV fitting.





      I also went ahead and ordered a 3 PSI wastegate spring with the order for the wastegate pipes, I have an EBC that I'll use to turn the wick up once I get things a bit more dialed in.

      • all that's left for the charge pipe is to put beads on the end. I really suck at welding aluminum, If I did more of it, I'd probably get better...



        I also worked on the wastegate dump pipe, I need to make one more piece, then finish weld it.





        here's a shot of the part of the fuel sender I cut off. you can see it's super tiny...

        • I did a bunch of work today, The fuel sending unit and the tank are back in, the downpipe and wastegate dump are fully welded and the engine is back in the car! I was super happy to find that mu charge pipe fits, I was worried it would hit the firewall.

          I decided against a "screamer pipe" and integrated the wastegate dump into the downpipe, the length of pipe will allow for expansion in an arc, instead of linearly, which should reduce strain on the welds. I haven't decided whether or not I'll split the downpipe to both sides of the car, or just run it to one side with a single tailpipe.



          The downpipe and wastegate dump clears everything just fine!



          as does the charge pipe!



          Here's how I left the car, I have a ton of work to do still, but I might just crank it before the end of the month!

          • This makes me want to post on update of my project. Let me go find a pick from 7 years ago when I parked it in the garage...

            Always enjoy seeing all of the progress on this. I can't wait until you get a chance to fire it up!

              LOL! I know the feeling!




              ______________________________

              bleh! Last week, I was at work for about 110 hours, so as you can imagine, I haven't had much time at all to get anything done.

              Today was a busy day, The intake is bolted down "permanently" as is the alternator, idlers, and the belt is installed. additionally, I put the 3# wastegate spring in, and got the ports clocked the way I want them. I was going to make and install all of the boost/vacuum lines, but I somehow never ordered the right fittings... DOH. They're on order now, and should be here Tuesday.

              I needed a place to install my main power ground on the engine, and had been trying to some up with something acceptable for a while, with no real luck, then it hit me, use a longer bolt for the top idler, then use the overextended threads to install the ground on.




              I also got the oil feed line plumbed and connected, the harness re-installed, and some other odds and ends sorted.



              the last thing I did was re-evaluate "the list"

              To start the car:

              heater/coolant hoses made/installed.
              boost and vac lines (awaiting fittings)
              Alternator charge wire
              fix the flex fuel sender wires (they're a bit too short...)
              Wire the other half of the fuel pump connector
              install the axles
              fill the transmission
              prime the oiling system
              set the ignition timing
              add chafing protection to the wiring near the battery
              wire in the O2 sensor LED


              To drive the car:
              new front right brake line/bleed brakes
              bleed the clutch
              finish the roof install
              install a new windshield
              reinstall the windshield wipers
              install the decklid
              install the front tub
              install the upper front fender bolts
              install the rear wheelwell liners
              opcheck all of the lights

              • Work has been kicking my ass, I really want to start the engine before I go back out to sea, but I'm not going to hold my breath on it, and if it doesn't start before I go, it might be early next year before I can get back on it... I plan to take some odds and ends out to sea with me so I can take a shitload of measurements and when I get back, punch them into a CAD program.

                Today, I knocked out a bunch of stuff on the list, The alternator charge wire is made and installed, the axles are back in the car, and the transmission is filled. For those of you that don't know, the F23 transmission's oil fill is tiny and very easy to overflow... I also primed the oil system with a pump sprayer through the turbo oil feed, no leaks were observed. I also made up the rest of the vacuum and boost lines, as well as the heater core supply line. I was going to wire up the fuel pump connector, but I couldn't find the other half of it, until I started typing this... I'm hoping tuesday I can get the thermostat outlet hose figured out, and start filling the cooling system, but the way work has been, I'm not sure it will happen.

                The list looks short, but I'm sure I'll find a dozen or more things to add to it before it starts.


                To start the car:

                fix the flex fuel sender wires (they're a bit too short...)
                Wire the other half of the fuel pump connector
                set the ignition timing
                add chafing protection to the wiring near the battery
                some kind of a base tune...

                • well, it popped off today! I have lots of issues to sort out still, for some reason the DBWX2 and the MS3 pro keep loosing coms, and the only time I could get it to do something that seemed like a reasonable idle, was when it was so pig rich it was billowing black smoke, otherwise as soon as it starts it immediately jumps to 2500-3000 RPM. I'm going to start by troubleshooting the can bus circuit between the MS3 and the DBWX2, as I don't have a reason to believe there's a vacuum leak that big anywhere, and the default position for the TB is fairly far open, so that could be part of the problem. Hopefully I can figure out whats going on with the can bus and that yields some kind of progress.

                  Anyways, here's a video of the first start.

                  • I've thought about getting that DBWX2 box, it would just be nice if there was a more universal option, like other ECUs work with.

                    I'll be interested in seeing updates to it's functionality.
