    Turbo YUGO

    " This is my tale of how I plan to build a 1.1L 200fpt YUGO.
    To run at the GRM 2004 Challenge. It is being done as
    I am able to get the parts and time. So, it has no
    specific build order, just a time and money limit.
    (April 2004, $2004 Challenge)

    It all started two years ago I was given a 3K turbo.
    That is why I'm using it. It has bean a pain to work
    with! But it was free.

    I had to design and have adaptor flanges made, one
    for the exhaust and one for the turbo. The exhaust is
    made to match the very common T3, because one day,
    someone may want to build a turbo car, with the
    affordable T3. The adaptor for the 3K is T3, so I
    could use it. After bolting up the turbo and exhaust.
    I was able to see where the lines have to go. For oil
    I ran a line from the oil presure sender. The
    oil drain is made from a 1/2" x 18" flex gas line.A
    ?" NA welded to the turbo drain and to the oil pan.
    Coolant is from a line I made in to the thermostat
    housing, and one in the heater hose linewith a tee
    fitting.

    The first test did okay. After installing and
    removing everything to get it to fit, I forgot
    to put a restrictor in the oil line, and blew out
    the oil seals. That was not so bad. What was bad, was
    what I did after I got the turbo off. I broke off the
    impeller nut. That was bad, very bad. You cannot just
    buy a one for the new 3K turbo. So it was off to Ebay.
    I found a core turbo for $33. And now the waiting
    begins...

    I went to 'Joe Boys U Pull It' and found a VW Fox
    that still had a good fuel pump. Popped it out, and
    bought it. Got home with the pump and started the
    install. Designing and fabricating mounts for the pump
    and filter. I found varnish in the tank and all over
    the pickup. The tank had so much rust in it that it
    looked like someone put a bag of corn chips in it. So,
    I took the tank off and cleaned it out with a 3 foot
    chain and some solvent, replaced the rubber fuel
    lines, and installed the VW fuel pump. Then I
    installed a Mallory boost compensated fuel pressure
    regulator. Then I installed the carb that I have
    sealed up, and set idle. All looks good for now.
    later, I installed the sealed carb hat and run some
    boost, and test lines for leaks. There were no leaks
    or burst hoses at 100psi fuel pressure. But I did over
    presser my gage and now it reads 15psi at 0 psi.

    Finally, the new turbo came in! After getting tired
    of having to install the turbo in 2 parts. I found
    that if I rotate the turbo 180 it fit better. It no
    longer rubs the cab. The exhaust can be run without
    any problems(wont have to
    alter the center support). Everything looks like the
    factory may have done it.

    For the oil line I gave up on the ss tubing. Im
    using ? hydraulic line. I put a bolt in the with a
    3/64 hole drilled in it, for the restrictor. It is in
    the banjo fitting on the block. So there is only abut
    7psi on the line. I now think that the 3623psi that
    line is rated for is overkill.

    Made the last part of my down pipe, out of
    cardboard. Took it to the muffler shop where they
    bent the pipe to my template.

    Found an intercooler, from a 91 Ford Probe GT.
    After a lot cutting. It now fits! That is after
    removing the fuel pump. And rotating the distributor
    90, so the vac pod is not in the way. Worked on the
    intercooler pluming today, After only
    6hr I have the cooler plumed in. Not happy with it
    but for testing it will be okay. Got every thing
    plumed in nicely. Took car out for
    test drive. Every thing was going great when for no
    reason at 5-7psi the clutch slips. So
    now to replace the clutch. Got a new clutch, throw out
    Bearing and pressure plate. While replacing the clutch
    I had to replace a CV boot.

    Got it all back together. And took it for a test
    drive. The car now explodes when I hit 3psi, and just
    keeps pulling until I run out of fuel. Now, I need a
    larger carburetor. After some research, I learned a
    larger carb is going to cost 500 dollars! MegaSquirt
    is 130, and I have wanted to try EFI for some time
    now, and since I have a YUGO EFI intake that I cant
    use, I decided to try it. So MegaSquirt it is.

    I ordered My MegaSquirt and started the wait. It came
    in 2 weeks, much faster that I thought it would be.
    But
    it took longer to just have the some of the parts from
    Digi-Key delivered, about two days. I had my MS
    assembled I record time, about seven hours, then I
    assembled MegaStimulator, a necessary componenet.
    Got up and stated on the relay board, then the made my
    own DB9 cable. It had to be 15 feet long, as I have no
    lap top PC. Next I went to the auto salvage to get
    wire for my install. While making my harness, I
    decided to use General Motors relays instead of the MS
    unit. Just looked easier for me to use. Got every
    thing installed and then was ready for testing and
    tuning. I was able to get the car running with the MS,
    but tuning was a problem. I did not have a lap top PC
    and no alternator to power an A/C converter.

    It was fun playing with the car until one night the
    battery ran down, and left me stranded.
    And cold. 29F. So I went to work on installing an
    alternator. The problem being that the turbo
    is where the alternation would normally be.
    So, after a bit of seaching, I found space where the
    air pump was supposed to be located. I made a bracket
    that bolts to the water pump housing.
    Now I have a charging system. I aquired an A/C
    converter and browed a lap top PC. MegaSquirt is so EZ
    to setup and tune when you have every thing you need.

    Got my map set and started testing the boost limit.
    The stock Injectors could only handle 5psi. So I
    replace them with 19lb injectors. I still was unable
    to get past 5psi. When ever I got up to 5psi and 5k
    rpm, the engine would not turn any higher rpm.
    Not fun because the engine will rev to 7k rpm usually
    with no problem. Every thing works grate with that one
    exception.

    Went to work on the cars handling. I cut the front
    springs, replaced the bolts on the rear leaf spring to
    lower it. Also, I installed new bushings on the front
    A arm and sway bar, and installed a rear sway bar.
    I took the car on a test drive, and was happy with the
    results.

    To help prepare myself for the racing scene, I went
    to Texas Motor Speedway for a Panoz Racing School
    event, Fast Laps. It's a 'run what you got' type event
    on Texas Motor Speedway's Road course. Each session
    is thirty minutes, then you can go over how to improve
    your times with the instructors. It was full throttle
    nothing under 50mph up to 90mph in my YUGO.
    I ran at 5psi the hole time. 3 sessions at thirty
    minutes each then made The 3+ hr drive home. What a
    Blast!!!!!!! I Loved It!!!!!!! But by heart I am still
    an Auto X man.

    After months of trying to fix my running problem.
    I replace the coil and that?s all it took.
    Now I have no RPM limit? Okay maybe I have one 8k?
    Armed with a new coil, I went on a test drive.
    Fiannaly, no more dead zone above 5k rpm.

    For more 'driver tuning' I made a trip to Dallas for
    an Auto X at Pennington Field
    <http://autocross.com/texasregion/april182004.shtml>;.
    I entered as tSM (street Mod on street tires). I was
    not prepared for how well the car handled, or
    accelerated. The car handled much better than I
    thought it would. The adrenal rush was out of this
    world, and I had a hard time focusing on my driving
    and the course. I was able to finish 13th out of 20!

    Later, after I arrived home, I looked the car over to
    see what to do to improve the handling even more.
    That is when I noticed that the rear sway bar mounts
    had ripped from the car. It had been making a sound
    that I had looked for many times, but could not
    isolate. I had to make repair plates to weld to the
    frame to hold the sway bar, and repair the hole in the
    frame. It is not pretty but it works. Now the car
    should really handle!

    The MegaSquirt worked flawless on the 1000 mile trip.
    To Gainesvill FL. Where I competed in the Kumho Tires
    Grassroots Motorsports $2004 Challenge.
    I had a grate time and made some new friends.
    I some how did not win. I came in 48th out of 77 computers.
    Would have come in 47th. I helped the only other car with
    MegaSquirt get running. So they promptly beat me.
    That?s what I call thanks."

    Nadam se da ne zamerate na aktivnosti italo-fana u vashoj garazhi!

      Dreaming...5PSI = 0,3 Bar
      Originalni motor , problem sa kvacilom na 0,3-04 bara, znaci na oko 85KS

      Decko nije jeo dovoljno pasilja

      Prica li o originalnom neradjenom motoru koliko sam shvatio jer nista neprica o tome, tesko da se dohvato efekta, obrtni momenat je dobio, nemogucnost kvacila pokazuje to, puno ambicija, nepokazuje preteranu strucnost nazalost
      Att mäta är att veta...to measure is to know...meriti je znati..
