    My GRM $2006 Challenge Car

    i have leaked a few pictures in the past year but i wanted to keep it under
    wraps so i didnt give my competition any ideas.

    I bought a 318i for $255 and an eta parts car for $200. suspension, brakes,
    short block, and tranny off the eta went into the 318. found a b25 ($44) head in the junker that needed new valves and rebuilt it. the Eaton M62
    supercharger was $40 from a fellow GRM competitor. Engine management was a $200 megasquirt n'EDIS. the 36-1 wheel/sc pulley came off an escort and the wasted spark system out of a Ford Contour (all really cheap parts from a PAP in ATL.) Springs not meant for this car were 600lb front and 450lb rear (@ ~$85). rims i got from Max in Germany dirt cheap and the tires were free from another fellow GRM'er. as for time, lets just say i busted my ass for an entire year. i would imagine i have a over 1000 wrench-hours on it.





    I ran a 13.8 1/4 mile @ 102 mph with some wheel hop and bad shifts before the oil drain plug decided to let out a steady drip so i decided to call it quits there before making a mess on the track.
    The auto-x brought me a time within the top 33% which was enough to keep a step up on the GaTech team. Yet their paint job wow'd the judges in the concourse eventhough my engine bay received Honorable Mention, placing them 3 thenths ahead overall. It was a very exciting competition among the e30's. I took 22nd place and GT with 21st!!



    the crank pulley took one afternoon to properly mount and the entire second day to fabricate the mounting hardware for the supercharger. As mentioned in another thread, yes, the alternator was relocated to the other side. a simple mounting bracket was constructed and the dip stick had to get out of the way. BTW, the bay is white because the rest of the car was supposed to be white as well. i just ran out of time. would have been funny seeing three e30's there and all of them in white.







    David and his friend, both from Boston, 2-wheel dollied their car all the way. They placed outstandingly for a stock engine w/ 19# injectors and tuned suspension.



    And GT finally got the turbo on and a decent paint job over the flat black from last year. If only they had those slicks for the auto-x, they would have kicked butt.

      First time I've seen a cone filter sticking outside the grille. Pretty cool. But what's that yellow thing on the other side of the grille?

        i saved a few bucks by using a rain gutter guard wrapped in an old thin t-shirt and clamped onto the TB as my air filter

          Um, that spring rate setup is backwards. You should have the lower rate in the front, not the back.


          Keep it slideways!!

              you do what you got to do. i'm trashing this setup next year but absolutely loved the 600 rate in front. not to condone the setup, but the funny thing was, with those rates, stock front sway, no rear, open diff, the dynamics didnt give me enough problems to NOT be able to handle the car in and out of turns. the slalom sucked though, imo.

              do you guys see the pics? i probably need to move them ...edit, damn. exceded BW

              also, i put it on the dyno the day before i left, bad idea. the idiots at the shop ... well, we wont even go there. i blew a tire too. but three intake eccentrics rolled back and i was still putting down 200whp at around 3k rpm. the top end was dropping off, i think because the vacuum side of the charger wasnt getting enough air. surprisingly enough, these 19# injectors still had a little room to go. lastly, i'm not keen on the M62 design. i like the internal wastegate but i think the system would be more effective with a larger intake port and some crazy external wastegate or BOV... what ever its supposed to be called.
