  • Chapter 36 - The fix

    so in the last chapter, i described how i had a huge p/s leak, and that my a/c belt had came off

    but i kept driving the car around during the following week, so i did what any smart person would do in that situation...
    my p/s pump was going to burn out because there was no fluid going thru it
    and i didn't have to time to remove the radiator and a ton of stuff just to remove the belt
    so i just cut it... i had another spare one anyway


    the thing is that exactly 1 week after the track day, i was going up north to my chalet, a 4 hour drive,
    so i really wanted my p/s and a/c to work for that trip

    during that week i drove the car to work, without p/s, on the highway, it was a freaking pain!!! i couldn't feel my forearms when i got to work because i had to hold onto the steering wheel so much, darn 265 tires


    the first thing was to figure out why my brakes weren't doing crap, so i took the whole thing apart to inspect it ;

    the rotors looked super glazed, no wonder why it wasn't braking



    i took the pads off, and all the cylinders boots looked fine, no sign of damage anywhere



    then i turned my attention to the rotors,



    in an attempt to reduce the awfull awfull noize the Hawk HP+ were making (at that time) i chamfered the leading edge of each front pads



    i also drove past AutoWorx and borrowed some leftover cans of Wurth Anti-squeal



    after applying a good thickness, i put everything back together



    i then check the wear of my front tires and quickly realized i couldn't finish my summer with sooo much camber wear



    the problem wasn't actual camber, but way too much toe out, because like an asshole i had changed the alignment front VAG Motorsport's settings because they were a bit too extrem



    so i went to a tire shop that my dad often deals with, and had both front tires flipped, meaning that the camber wear would now be on the outside of the tire rather than the inside

    it looked like ****, but at least i could drive for the remainder of the season



    ---------------------------------

    the next day, i checked what my p/s and a/c problem was

    and sure enough i had lost the complet a/c tension pulley assembly, so i got on GTRC and found another one, rather quickly



    i then saw that my main p/s hose was cracked open,
    after looking under the car i realized that line was part hardline part hose, but 1 piece all the way from the p/s pump tp the rack&pinion head



    so, seeing this was going to be a real PITA to fix, i enlisted the help of my father for a rare occasion

    first i had to remove the radiator, argh



    both of us spent a good 3 hours underneath the car to remove the line without bending it too much since i didn't want to replace the whole thing
    we had to snake it thru the subframe, motor mounts, swaybar, etc, etc...

    and this is what the whole fawking thing looks like



    believe me you do not want to replace this line, it is by far the worst job i've ever done on my car

    the soft part of the hose was completely torn open, even though its super thick and solid



    i called Nissan just for kicks, and the line was worth something like 300$
    and would take 3 weeks to arrive from japan



    since i didn't have time to get it fixed myself, my dad brought it to an hydraulics shop
    they didn't have the same fittings to go into the p/s pump (DUHH) so i told my dad to get something as similar as possible
    and also, the facilitate the "putting it back on" part, i told him to get the line cut into 3 section and using fittings we could assemble it back on the car

    but, just my luck he had it cut just a couple inches from the spots we had discussed

    this is how it looked



    how the assembling fittings look



    the crimped section



    and the end fitting, which looked completely different




    problem is, we had received the line on the friday, when i was supposed to leave at the break of dawn on the following day

    so on friday night, my dad and i went back under the car to get the line back into place

    but since the assembling fittings weren't in the right spots, it actually made it even more difficult to fit because we couldn't reach the fittings with tools to tighten them up

    it took another 3 hours just for that

    but out of luck, the standard banjo fitting at the end of the line was just the right size to fit on the p/s pump and into the bracket that prevents it from rotating



    while working on that, i saw that the dust cover on top of the rack&pinion was cracked, and that the rack&pinion itself was leaking just a bit



    but i realized, that it would have been much smarter to simply replace the whole line with a complete soft line (high-pressure nylon braided line), it would have been much easier to re-install, and much more reliable (as you'll see later in another chapter)


    after that, it was already pretty late, but before putting the radiator back on, i wanted to fix the A/C

    luckily i had received a pulley from Brian Ellis (Bellis)



    quickly i bolted the pulley assembly onto the car, but since the original one wasn't there at all anymore, i couldn't compare
    i fitted the spare A/C belt over it

    reassembled all the other belts, the fan, and put the radiator back on

    then i filled the radiator simply with (inexpensive) distilled water, and a bottle of Redline WaterWetter to make the water more viscous



    filled the p/s system with good quality fluid




    after everything was reassembled, only then did i start the car to see if there was any problem

    there was no leak, but a loud ''squeak'' could be heard
    it wasn't coming from the p/s pump
    but when i checked underneath the car, the sound was louder
    so i stopped the engine, and started it again
    it was clear the noize was coming from the freshly installed a/c pulley
    i could even see rubbing marks on the support right behing it
    only when i saw the pulley jam, and the belt still turning and .. smoking did i yell to my dad to stop the engine
    it was clear i was missing some sort of spacer between the pulley and the support

    so i sent a text to Brian, asking if he had sent everything related to the pulley's assembly and he replied that he did

    my dad was looking at me, with a look that meant 1 thing; ''son, we're going to have to take it appart again''
    ohhhhh no

    by taking the nut of the pulley and prying it a bit, i was able to take it off the shaft without having the belt slide off the pulley

    so at first i slid a 1/2" washer on the shaft, to space the pulley outward, and tighten the pulley back on

    started the car, and saw that it wasn't enough
    fuuuuuuuuu

    so i did the exact same thing a second time, and with two 1/2" washers, the problem was resolved




    even though it was close to midnight at that point, i still decided to check the spark plugs, since it was a 600km ride in the following days

    i cleaned the plugs, and everything was fine!





    so the next day, saturday, i got up at 6am, and drove my perfectly functionning car all the way to my chalet

      • Haha I really don't want to change that hose.

        And I'm almost positive there was not a spacer one mine lol There wasn't even a belt. Maybe when who ever took the belt off they forgot the spacer if there was one? Haha not sure, but I'm happy you improvised and got the job done! Nice track pics too, I like

        I have to get my car up there for some track days. You should also come done to some of ours!

                  • Chapter 37 - End of an epic summer, part 1


                    so before storing the car away for winter, i wanted to keep fixing some issues

                    a couple days after my great little 600km trip north, i called Autoworx so i could pic up the parts they had miss-painted and also those they didn't even paint, AND to get them to put my mess grill back on

                    the receptionnist told me to come by later that day, that everything was ready and the guys would fix my car

                    of course when i got there at around 6;30pm, no one had a clue i was coming since the douche receptionnist never told anyone

                    they scrambled around to find my parts and started putting them back on the car



                    i asked them for some copper spark plugs, and was told they didn't carry those type of plugs
                    but of course that what THEY put in my car the year before
                    so i told him that thats what i was using, NGK-R copper racing plugs, and was told that it was impossible, that my car wouldn't even start with those plugs, but of course i myself had put a set of those plugs in and driven over 10,000km with them
                    so i told them to F-off and i left
                    that, was the last time i went to Autoworx (or Carworx as it is known now)


                    -------------------------


                    the second thing to fix was my crazy backfires, and ''misfires''

                    during the 2010 Ultraride i was having major issue with keeping my speed steading as i would get tons of misfire, no power, and sometimes flames coming out the back

                    wanting to know more about the ''flames'' coming out the back that some people had seen, i did a little experiment

                    i went out for a drive on the highway, and positionned my GoPro HD camera on the rear bumper in 60 frame per second mode to catch any occurence

                    well....

                    this is the kinda of misfire / backfire i get all the time when applying very little pressure to the throttle,;



                    the night before, i ajusted my TPS, since then my car as been running super rich (based on my AEM wideband)
                    and when i left off the throttle to slow down under compression, instead of going full lean like before, now it stays really rich (12 afr) for a couple seconds (5-6) before going full lean

                    so this is what i got that night, in just 15 minutes of driving;

                    enjoy the fireworks;










                    having still no idea what was causing this, i tried messing with the TPS and AAC valve

                    oh and also, when i ajusted the TPS, my idle got down to ~500rpm ish and was pretty rough, but still idled at 12afr
                    tried to ajust the AAC valve and throttle cable tension, but couldn't find the right comination


                    luckily right after the Ultraride, i called Almasi Tuning to setup an appointment to fix this

                    when i got to his shop, we mounted to car directly on the dyno,

                    we found the problem

                    at first i explained my problem to Robin, he really couldn't see what it could be
                    i clearly explained everything that happened and when it would happen, even showed him the pics of the backfire and small blue flame (not a backfire, much worst)
                    he really like the blue flame one

                    then on the dyno, he checked its idle, then kept the RPMs at 3000
                    it kept doing "Pff Pff Pff" and such
                    AFRs were all over the place, good thing the UEGO wideband is digital because a mechanical needle wouldn't have been able to move fast enough

                    then put it in gear and tried to keep it at 100km/h, again Pff Pff

                    so then he checked the Consult on his laptop and adjusted the TPS to the correct voltage

                    after that was done, he just kept staring at the screen

                    after a couple minutes, he went; WTF

                    the O2 sensor signals were completely f'ed up
                    so he went to check on the connectors,

                    the O2 sensors were swapped !

                    i mean, the connectors are different so you can't swap them this way, the actual sending units were each plugged into the other's dump pipe

                    un-ending loop

                    when sensor#1 was rich, it told sensor#2's injectors to go lean
                    then sensor#2 runs lean, and tells sensor#1's injectors to go rich
                    thus the un-ending loop

                    thats why i had a blue flame constantly coming out the back
                    3 cylinders were running FULL RICH
                    3 cylinders were running FULL LEAN
                    thus creating the perfect mixture of air/fuel in the exhaust

                    and a blue flame is very bad news, it means the flame is extremely hot, much hotter than an orange flame

                    so instead of physically swapping the O2 sensor back, which would have taken the whole afternoon, Robin simply swapped the pin-out in the ECU board, which took 2 minutes for the exact same result

                    another thing i already knew and everyone should know, is that the GTR ECU uses the O2 signal only when its under ~4lbs of boost, after that it only relies on MAF and boost signal

                    thats why i had absolutely no problem under boost

                    then fired the car back up, and it ran PERFECTLY

                    did a couple pulls and ALL my issues were gone, and almost no more turbo shuffling either
                    YEY

                    than Robin re-tuned the car with the proper boost controller settings while i was setting up the EVC-S myself from the passenger seat


                    the bad news, driving 500+km with that issue hasn't been good on the engine, either the spark plugs are destroyed (completely burnt or fooled)
                    or as Robin said, maybe i melted something in the cat back (HKS Legal) and made it much more restrictive
                    or i messed up the compression in some cylinders,

                    ..because i lost 26whp
                    even with a much MUCH better looking boost curve


                    then i drove home, and i must say the car has NEVER ran so well, its unbeleivable how smooth it ihad become,

                    and another good things is that i'm still doing small backfires, but the usual "correct" way, just when i let off the gas completely,
                    thats because of the decat
                    then it immediatly goes to full lean like it should

                    the man, the legend




                    when i got home, i checked the sparks plugs



                    they were messed up, so i didn't take any chances i put a new set of BKRs back in

                    and i also did another compression test



                    the average had gone down a tiny 3 psi since the beginning of the summer
                    but i also found out much later that i wasn't really doing the test properly


                    --------------------------------

                    another thing i wanted to fix was... my brakes again..
                    my fix didn't really fix them because they still wouldn't brake and they were making even more noise then before, it drove my girlfriend crazy during our trip up north

                    i say byebye to the AMS rotors and put the good ol' stockers on



                    and the Anti-Squeak i put on the back of the brake pads didn't last long since there wasn't a back plate to spread the brake force



                    so using a piece of sheetmetal, i cut a set of backplates shaped like the pads




                    -----------------------------

                    then i wanted to finish my center console

                    so i bought a piece of carbon fiber, already cut up ti fit my controllers, from Nelsonmxmarc



                    but then i had to find a new spot to put the A/C control, how about the glove box...

                    i started by removing it, which is already a huge PITA



                    then drilled a huge hole in the back of it, took the wiring harness for the a/c control and passed it behind the console and thru that hole



                    then put everyback in place, but because of the lenght of the wiring harness, i couldn't put the control right side up,
                    so upside down it was



                    after that i used lighter fluid to clean the back of the CF panel and using industrial double sided tape, placed small blocks of wood behing the panel



                    then using small strips of metal and even more tape, i placed all 3 controllers in their respective hole, and secured them to the panel from behind to make it super clean





                    and finally fixed the panel to the back of the console trim with yet again double sided tape

                    Skylab TSC
                    HKS Type-1 turbo timer
                    HKS EVC-S boost controller

                    RESULTS

                    • Chapter 37 - End of an epic summer, part 2

                      a couple days later, i participated in the 2nd round of the 2010 Ultraride, the ''Rewind''

                      and beeing one of the most recognize participant of that event, i was invited to a day of filming with the UR crew for a special DVD they were going to make

                      during our drive to the last filming spot, this incredible picture was taken by FuelRiders photog Guillaume Boily



                      at that last spot, i was the last one to leave, and the crew told me the film was missing some action, so i proposed to generate some

                      AWD donuts bro'



                      you can even see some spark coming from my front right tire that had some exposed mesh

                      sadly, because of some issues between the producers (FuelRiders) and the event organizers (UltraRide crew) the DVD was never released


                      i found out the next day the repercussion of that action

                      my rear tires (Falken Azenis) were now completely bald
                      don't be fooled by what looks like thread, there is nothing left (look where the tire touches the ground)
                      they were done anyways




                      i added a little TOW sticker



                      and i also started my own little trend by putting all my unused stickers inside the trunk lid



                      and then put the car away for good for the winter
                      the engine oil was swapped with cheap castrol oil, and the radiator was drained and filled with mostly prestone




                      ---------------------------------

                      in retrospective, 2010 was an incredible year

                      i was my first time embarking on a build project of such scale, all by myself, in the home garage

                      i did most of what i set out to do (read : the master plan) and even more

                      as i said before, the best way to get into a project like this, is to make a list of goals, plan them all in advance, don't stray too far off the goals, work hard, and don't give up

                      i think writing all this 'blog'' here on GTRC was like a therapy for me, because alot of times i just wanted to quit, but talking to people on here just gave me more motivation


                      i am very happy with what i was able to accomplish with my knowledge and abilities, since i'm not a mechanic nor a genius


                      thats it with 2010, my most epic year ever with everything that happened, evetthing i did

                      but of course the project of the U.S.S BNR32 still isn't finished, work resumes in 2011 and gets even more epic

                      i'll keep updating this thread with stories and info regarding 2011, i hope to finish before the 2012 season starts (ugh)

                      thx to all of GTRC for the support

                      /2010

                      to see how the GTR looked at the end of 2010, plz go see this (2010 photoshoots of teh GTR)

                      • Nice work as always Frankie! I'm suprised you're having problems with the AMS brakes. I've got 2 seasons on mine with no issues other than their pads are pretty weak.

                        • well i don't know what to say really about them, but they just didn't work out for me, so i sold them a long time ago
                          i used the stock rotors for all of the 2011 season with good results, upgrading to DBAs for 2012

                          the AMS pads are total weaksauce, i hope you're not using them on the track..

                          • HAHA! I did... ONCE. I went back to The EBCs that were on the car when I bought it. Significant improvement but still not what I'm looking for... Suggestions? I'm looking for a track pad (I'll swap between st and track) but won't eat my rotors up.
                            Also I think I mentioned to you before. A few friends and I are looking to do Tremblant in August with the Boston BMW club. Any interest? We'd likely have room for you. Friend of a friend has a Chalet.

                            • Wow I'm kinda surprised the pads and rotors didnt work out for you but this time around I think I'll give something else a shot. With the brembo calipers did you notice a big difference? Right now I am contemplating doing new calipers and brake setup. If you think it's worth it maybe I'll swap to a brembo set.
                              Miss driving sooooo bad! Need to get a car on the road ASAP!

                              • bobbo ;
                                well the Hawk HP+ pads were great off and on the street,
                                but with the weight of my GTR, i was thinking of upgrading to Pmu HC+ pads this year, still streetable pads but that can take much more heat

                                i'd love to come to tremblant with you guys, it just depends on price and the exact date since, since i'll probly be in the final exam portion of my summer semester at university

                                chris;
                                the brembos felt great this year compared to 2 years ago when i had the exact same setup but with stock sumitomo calipers
                                because of their size they are a bit easier to modulate, and you don't need 1000lbs of force on the brale pedal to slow down
                                i think its a worthwhile upgrade, but if you can go bigger do it, GTRs are heavy
