Winter project... take my championship DSP car, and RUIN IT! :lol:

40577_480085178447_8036653_n.jpg

The idea is to go from DSP to F-prepared... basically gut the car, keep the stock drivetrain, lose about 500lbs, and switch to slicks. Faster, more fun to drive, but same reliability as currently.

THE CALM BEFORE THE STORM:

Look at all these things that don't make my racecar any faster... ;)

    Whoa... nice. Is it hard to corner-balance DIY?
  • edited November -1
    It's not that hard but it is certainly time consuming.

    We arent corner balancing at this point, just using the scales to see how heavy the car is and how the F/R balance has been changing.

    In DSP trim the car was 2880lbs +/- 5lbs with the rollbar.

    My goal for 2011 is 2400lbs including the rollcage.

    Ha, Ben, have I even been a drag racing guy? I am building an autocross, hillclimb, solo 1, and general shenanigans car!

    The cage and chassis work are being done by Lowe Group Racing in Carnation, WA
    Their shop car is a tube framed A-arm conversion widebody E36... /drool

    For my car we wont be going that far, simply not in the budget, but we will be doing a complete 10pt GT cage coupled with some floor plan, rear seat, rear parcel shelf, and trunk removal, replacement with sheetmetal.

    hey mark did you get a hold of kiesler to answer some of your transmission questions about their TKO transmissions?

    If you get tired of trying to figure out what to do about putting a standard in their you can always go back to an auto.. I have done some really fun things with TCI stand alone computers for the 4L60E auto transmissions... we can get you all set up with paddle shifters and everything.. lol...

    hahaha, that's funny.

    when you first posted the pictures with the engine pulled i thought you just pulled it for the cage install or for some other reason and i was actually going to suggest an LS1 :P

    this car is going to be nuts....

    That's going to be a beast of a car, haha.

    Quick question - does camber plates bump me into a specific class? With my "winter projects" I'm ending up in DSP, but are camber plates allowed there?
  • edited November -1
    we know one thing for sure is that we know that LS1 was never raced. I looked for awhile to get this engine.

    Re: transmission

    Decision has all but been made that I will source the best used T56 I can and simply use that. I dont want to re-engineer a bunch of stuff to accommodate a different transmission, for 2011, the goal is just to get the car up and running.

    Re: camber plates

    Camber plates are specifically legal in any street touring, street prepared, street modified, prepared, or mod classes.

    Good thing to start with a 99 LS1, the 98's have a different PCM that make tuning next to impossible, the 99-up in the hands of a top LS1 tuner like FROST can run 8 Sec boosted drag cars with 800hp on a remapped PCM. The 98 also have a different intake manifold and PCV system that nobody, even GM makes replacement hose for so the factory fix is a 2002 intake that also gains 10-12hp (and stock legal mod)
    If you are going stand alone, as good as the SDS systems are, I'd get HP tuners, for LS1's you don't need to guess, everything has been done and dyno proven with maps on download.

    Thier are a few E36 racecars running LS1's in thunderhill 25hr race, be careful as car with High G-load can cause oil issue with stock pans, check out the roadrace section of LS1tech.com, their is a guy with the same car with full aero that has a write-up on it. Solo races are fairly short though and I haven't seen any issue with my 98 on Motul yet, but my car is certainly not a high-G slick tire car.

    Thanks for all the info, much appreciated. I have an LS6 intake that will be going on the car and I am definitely going to run the reflashed 99 PCM to try and keep costs down as much as possible.

    I am going to run a baffled oil pan from ImprovedRacing, while you are right that Maynard (the guy with that crazy LS2 based E36) has had lots of issues with the oiling, the solo events and what not that the car is being built for wont see that type of sustained cornering as there arent many sustained high speed corners. With that said, this motor is the "test bed" so it is a bit of a sacrificial lamb, hopefully lasting me a few years while I save up for an LS6.

    Looking forward to getting started on it when I get back!\

    Some people have asked about the fitment of the LS1 in the BMW and what it will do to the handling of the car.

    This photo courtesy of Vorshlag is the best I can find demonstrating an LS1 installed in an E36 BMW. Technically this photo is of an LS1 installed in a Z3 engine bay but the Z3 engine bay is identical dimensionally in every way to the E36 3 series except that the Z3 is 2" longer in the very front section which you cant really see in the photo.

    166456_1707501577949_1550367655_31694948_4815799_n.jpg

    Edit - another photo courtesy of Vorshlag, this one in a 3 series identical to mine:
    n1550367655_30255991_5797872.jpg

    As you can see, the motor will fit neatly next to the stock brake booster and master so nothing has to be changed there (ABS unit has been moved further forward and I will have to do the same in my car). Steering is also unchanged with one exception which is the stock BMW linkage between the steering column and the rack includes a big rubber connection point which is very close to one of the rear headers which would not stand the heat coming from the header. Luckily Vorshlag makes a very nice drop in aluminum linkage replacement which not only will deal with the heat but will also have the benefit of removing one of the points of "slop" in the stock steering arrangement.

    The motor itself is actually lighter than the 6cyl it replaces by almost 20lbs with a full host of accessories thanks to its aluminum construction (although the T56 6-spd transmission is almost 30lbs heavier than the BMW 5spd so its a wash) and, as an added bonus, sits lower in the chassis and more rearward than the I6 (the V8 is completely behind the front of the shock towers as you can see while the I6 BMW motor extends almost another 4" forward).

    As the days tick on I am getting more and more excited about this swap and am really looking forward to it, although everytime I identify a project that will have to be tackled, several more pop up, this really is going to be a project with 3 or 4 major steps and about a million "little" ones.

    For sure! who could have known that once you start removing interior bits to shave weight, the whole damn motor would fall out!! crazy how its all connected :lol:

    No photos for this update but a few things to report.

    While I would have loved to been out at autocross on Sunday, the day was spent getting the new trailer sorted out for the car - installing anchors in the floor, etc. to precisely position the car to maximize the amount of space in the trailer.

    Yesterday Kyle and I dropped the car off in Seattle for the cage and fuel cell installation, hopefully should have that back in around two weeks so we can get the interior and engine bay finished and off to paint.

    I have had absolutely no luck finding a T56 stock Camaro transmission, however, it is a well known fact that I am dangerous when left alone with eBay and a Paypal account and true to form, I did manage to find something a little different:
    Not a cheap, sensible, easy to work with T56 transmission

    Although this transmission is going to require some engineering to get into the car, it should be great when it's done, it is a 4spd dogbox that is a standard item in many GT cars and is considerably lighter and stronger than a T56, although I dont expect I would have ever broken a T56 with the modest power levels I am looking for.

    More updates coming soon!

    Jerold is already hard at work on the car and has sent me a few photos:

    164775_10150166386198448_502773447_8514835_32536_n.jpg
    Steel bulkhead removed, to be replaced with structural aluminum crossmember and sheet bulkhead to separate fuel cell from the cabin.

    164775_10150166386208448_502773447_8514836_2367957_n.jpg
    Rear trunkwell cut out in preparation for fuel cell and eventually rear diffuser.

    Front doors are now easily removable and will be skinned before re-installation for weight loss. Rear quarter windows removed so Jerold can weld the cage in the back half of the car.

    Nice Mark... I would look to see if you can get some money back on the drive shaft that comes with the kit you are using... I have no clue but the 4 speed tranny will most likely have a different output shaft spline count and it'll most likely be short then the T56... You'll need to make up a custom drive shaft... If you need a hand with that I know how to get it all messured up and a few places that can build them..

    Yes, I didnt order the T56 mounts, driveshaft, or throwout bearing adapter for that reason. The tranny will be here next week, once the car is back one of the first priorities will be getting the driveshaft ordered, I will bug you for some help then!

    Hi Mark, just got caught up on this thread. It seems obvious, but please reassure me that you are well out of DSP with this car now....right? What class will you compete in?

    edit: oh, maybe thats it there in your sig...XP/GTO, is that it?

    Long time no see, Ron!

    The car's new autocross class is "X-Prepared" (XP). In XP drivetrain is completely open and chassis modification/weight reduction are virtually the same. It is the 'abyss' as far as classing goes and the car is not the correct choice to be a nationally competitive XP car, currently a class dominated by Fred Zust in his widebody carbon bodied Lotus Exige.

    Yeah, i dropped out of sight last June due to "circumstances" but hope to be back on the tarmac sometime mid-this-year, once I find time to finish some repairs. I sort of guessed that your new class is "shenanigans" as you said, meaning you just wanna have fun! Could be excellent in hill climb eh? I must say that I just about had a shzzt when I saw that scale showing 2400 +/- lbs and before i realized you had left us straggling DSPers behind. Well thank goodness, maybe I can score a podium finish in DSP now, if only I could drive faster. I'm looking forward to seeing you drive your car at Pitt Meadows.
