    E30 M3 - Supercharged S50B32 [RNGTOY]

    [WARNING - LONG POST]

    Here is a writeup of my E30 M3 - the mods and track experiences so far

    It all started in the summer of 2006 when I went to the Nurburgring and
    got the Ring virus (http://www.m5board.com/vbulletin/showthread.php?t=74532)

    It was pretty clear that my M5 was too heavy for serious track use and was
    getting a bit too expensive for thrashing around.

    So the hunt for a track weapon started. It had to be light, fast and BMW

    E30's and E36's were an option but I don´t like the looks of the E36 but I
    have always liked the E30 M3 and decided to get one. These cars look just
    as cool as when they were produced - timeless beauty IMHO

    So I basically decided to get a white E30 M3 but that also lead to a power
    problem. The 4 cylinder S14 while a great engine is not that powerful and
    is crazy expensive to get more power out of it. So it was clear that a
    swap would be necessary to suit my taste for power.

    At the beginning of the year I went with a friend of mine to Germany to
    buy the car and also meet with a guy that breaks late model premium cars and
    has alot of BMW parts. He had some swap candidates for us to look at.
    After that we were going to meet with the guys that would most likely do
    the swap - a shop called Auto Tauber - they used to race in the DTM series
    in E30 M3's.

    Here we are at the car dealership that had some white E30 M3's for sale, my
    friend Sveinbjorn trying to decide which one he liked best:


    I was originally going to buy the car on the left but it turned out to be
    complete rubbish so we started looking at the one in the center. It turned
    out to be in pretty good shape - more expensive though and had just been resprayed.
    You can see it was originally black:


    Mismatched front seats - horrible Recaro drivers seat


    The car was not registered so we only could drive it on the lot to test:


    Felt good and we decided it was a good candidate for a track car.
    Finished the deal and since I waved some cash I got it for the same price as
    the original car I was looking at

    So we left the car at the dealer and went to meet with the engine guy.
    He had several S50´s and then he also had this:


    A supercharged S50B32 with only 1000 km on the engine itself and 5000 km on the
    SC setup and gearbox. 450-500hp. Very tempting!!!

    I told the guy that I would phone him in a few weeks and tell him what motor I
    would purchase.

    So after this we went to Auto-Tauber. We did not need to spend alot of time with
    them before we knew they were the guys to do the swap They were extremely
    knowledgeable and seemed very nice guys. We discussed different options - both
    a stock S50 and then the SC S50. We also got from them a ballpark figure for
    the swap.

    It was decided that I would ship the car to Iceland to have it registered and
    insured in my name and then ship it back to Auto-Tauber. It could not be registered
    in Germany because it had been imported into Germany with the condition that it
    would either be exported again or used unregistered in motorsport.

    We flew back to Iceland and had a friend of ours in Hamburg go and get the M3
    from the dealer and put it on a ship heading for Iceland. I registered it and
    insured it at the end of January, had some quick fun:


    The car was then back on a ship on it´s way to Hamburg 13th of February.

    By this time I had decided that I was going for the Supercharged S50 :evil:

    At the beginning of March I flew to Germany and drove the car from Hamburg to
    Auto-Tauber. They are located close to Nurnberg (not Nurburg). It was rather
    wet on the way:


    I always like those signs


    The built in Navi in the E30 is top notch:


    Finally at the destination - 100% stock and unmolested


    Got to see their pride and joy.... a pristine M1:




    We put the M3 on a lift and did a pretty thorough check
    on the car.

    The "todo" list became the following:
    - install the SC S50 motor & 6spd gearbox
    - Racelogic traction control
    - H&R coilovers
    - Movit/Porsche brakes, 322mm front, 294mm back
    - Brake cooling ducts
    - Recaro Profi SPG XL seats
    - 5 point harnesses
    - Roll cage
    - OZ rims, 17" Ultraleggara, 8" wide
    - Wideband O2
    - new bushings
    - fix rust

    At the middle of March I got some progress pics - they had already ripped the
    "hamster" out and had went and picked up the SC S50 motor, 6spd gearbox, headers
    and cooling for the watercooled intake. Here are some pics they sent me:


















    Some expensive wrecks :yikes:

    At the beginning of April I got some more progress pics:

    More rust than expected






    All would be fixed

    Engine & gearbox installed:

    At the beginning of May I got this update - brakes installed,
    engine placed correctly, propshaft being shortened, cooling system
    being installed:





























    And May 15th I got this video - the little monster was fired up for the first time
    http://www.onno.is/thordur/m3/gangsetning.wmv

    Picture of the seats/harnesses:


    Wires been tidied up:


    The car was driven for the first time with the new engine on May 17th:
    http://www.onno.is/thordur/m3/005/MVI_4575.avi

    The guys were in a bit of a hurry because I was arriving on the 25th to
    pick up the car and go to Nurburgring and Spa.

    Here are some pics taken just before I arrived - at some BMW gathering:

    On the 25th I arrived at Auto-Tauber with a few friends - we were
    on a "Eurotrip" in a few cars. My E39 SC M5, a stock M5 and an AMG SL55.
    We picked up the M3 and headed to the Ring. The M3 sounded awesome on
    the Autobahn - you could hear it for miles We had a minor problem
    when we were close to the Ring - lost 2nd and 4th gears. It turned
    out to be a minor issue that we could fix at the hotel at the Ring
    (www.ringhaus.com).

    So it was on May 26th I finally got to drive it in anger on the Ring
    on Toyo R888 after months of preperation. It was unbelievable!!!!!!!!!! :bounce:

    The grip was just crazy and the Racelogic traction control kept me out
    of trouble. Here are a few pictures:




















    There were some surprised people on track when an old "200hp" E30 overtook their
    much more powerful cars

    On the 29th we went to Spa for a track day - great day Excellent track and alot
    of fun driving in the M3 - surprised alot of guys at this MLR trackday.

    Woke up early to drive to Spa - very wet




    Did not look good for a track day.... wet wet wet.


    Finally at Spa - driving into the paddock area:




    Our fleet:


    We rented a garage in the pit area:




    Our neighbours:


    Cleaning the cars before going onto the track:


    Imola red ready to go:


    When the track started to dry I went out in the M3 - had driven the M5 in the
    wet earlier:

    Here I am explaining what is under the hood to a Porsche owner (in the blue shoes)
    who was not too happy with our speed difference


    Here we are going for gas at the end of the day - the M3 running on fumes:


    This gas station got alot of our money that day!!!!




    Everyone filled up and heading back to the Ring:


    It´s almost as the rear wheels are gunmetal coloured - alot of brake dust:




    The M3 performed flawlessly the whole day:








    Finally here is a video from SPA - http://www.onno.is/thordur/almennt/e...SPA_290507.wmv

    You can hear the Racelogic traction control kicking in

    After SPA I returned the cars to Auto-Tauber for some minor fixing. Returned
    again 2 weeks later for another trip to the Ring - this time I brought my girlfriend
    Lena. Here we are picking up the cars at Auto-Tauber:


    Lena got to drive the M5 for the first time - straight onto the Autobahn
    When we stopped there were some interesting comments....




    "This car doing 100mph is like a normal car doing 40mph"
    "It´s so stable going fast"

    At the Ring the car was better than before - the guys had installed stiffer springs
    up front. I was still using the Racelogic - here you can hear it in action:
    http://www.onno.is/thordur/almennt/E...lanzgarten.wmv

    Here you can see my girlfriend hold on for dear life!!


    Some more pics:






    Here the guys at Auto-Tauber had arrived for an E30 M3 meet and were checking the front
    brake disks that had started to crack.

    I also got some lessons from Thorleif in his white M3 CSL - got to drive behind him
    for a couple of laps


    After ca. 2000 laps he knows what he's doing

    Here is a lap in RNGTOY - had an Icelandic guy as a passenger so you will not understand
    anything we are saying

    The next weekend I met up with a friend of mine that lives in Luxembourg. He had managed
    to get us into a track day at Spa - held by the local BMW clubs. That day was very nice,
    alot of old BMW machinery


    A friend of mine was driving his E36 M3 GT and here is a video from his car when I overtake
    him - you can hear how loud the E30 M3 is :
    http://www.onno.is/thordur/almennt/E...07_2/SPA2a.wmv

    Also - here are some recordings from my car. You can see how it was pretty wet to
    start with but dried as the day went along (and got more fun )
    http://www.onno.is/thordur/almennt/E...SPA_230607.wmv

    I found that SPA is pretty hard on tires - more so than Nurburgring. My tires were totally
    finished at the end of the day.

    The next day I went back to the Ring and had alot of fun until the radiator failed.

    Here is a video clip:
    http://www.onno.is/thordur/almennt/E...ing_240607.wmv

    As you can hear in this clip I had stopped using the Racelogic - felt I was competent
    enough in the dry on the R888's.

    I was lucky to have the M5 on standby when the radiator broke in the M3 so I could continue
    having fun:


    I left the M3 at Ringhaus that weekend and the guys from Auto-Tauber picked it up the
    following weekend. I had by this time decided that I wanted to strip the car and make
    it a dedicated track car.

    I soon heard from the guys at Auto-Tauber and they had figured out why the engine had
    punched a hole in the radiator. One of the engine mounts had broken so the engine could
    move.

    Here are the pics I got once they got started:

    You can see some interesting things there, broken torsion bar mounting,
    busted guibo, some rust repairs, etc.

    You can also see the extra cooler for the intake. There would be 2 coolers
    and the sequence is intake->pump->pipe->cooler at rear axle->pipe->current cooler->intake.
    Hopefully this would be enough cooling and I would be able to monitor the chargecooler
    water temperature with that gauge.

    They would also install a strut brace as well as strut tower braces (a la cabrio) and adjustable camber plates.

    The next installment of photos would also reveal why the car felt so loose in the back.
    We originally thought it was because of worn bushings but it was far worse :yikes:

    As you can see the rear subframe was broken!!!
    It was rusted and the Ring & Spa had killed it. New one installed.

    There were also some news regarding the brake disks that had cracked.
    The guys sent pictures of the disks to Movit. The Movit guys said at
    first that his was just normal and were not going to do anything.

    The guys at Auto-Tauber then asked them for this in writing and when
    they asked why they said they didn´t want me to drive with these disks
    and they needed a name to sue if anything went wrong.

    A few days later there was an answer from Movit - new disks being sent
    free of charge

    It was finally August 5th when I picked up the car and headed for the
    BMW drivers training at the Ring. Here you can see the car in it´s current
    state:











    The car is pretty awesome. You can hear so much more now all the carpets and
    sound proofing is gone

    Here is a link to my trip report from the drivers training - alot of pictures and videos:

    Here are just a few from that thread:

    Also - my fastest lap so far
    http://www.rngtoy.com/thordur/almenn...09_oi_0818.wmv

    Anyways - it´s been one hell of a season with the M3.

    The car has performed very well so far - going to do some minor mods and have
    the suspension set up for the Ring by a local guru. Shipping the car to them in
    January to have it ready for Easter.

    Can´t wait


    PS. Hope I haven´t put anyone to sleep with this long post!!

    That was the most intense thread I've ever seen, anywhere, ever. Everything you did looks awesome and I'm jealous 100% about everything. I seriously cannot wait for a turn on the ring, that is one of my major life aspirations.

    So awesome.

    That was truly amazing. Great write up and fabulous car Wish I could own something similar to that one day.

    I am curious as to why you decided to go with a bolt in cage? I myself would not feel safe with a bolt in cage, especially in a car that is capable of such high speeds

    Real shame its a rust bucket... some scary stuff rotted away there that should have been addressed long before anyone let it anywhere near a track.
