    Supercharged Lebaron-24 hours of lemons

    Howdy folks,

    I made some inquiries for parts and discovered there was some interest in this build, its not a turbo per say but it is boosted anyway . What we have here is a 95 lebaron LX v6 with an Eaton M62 off a 92 buick park avenue ultra grafted to the original intake. Originally when I did this I used Megasquirt and the buicks 36Lb/Hr injectors but this time around I decided to try it with the stock electronics and an OBX 8:1 FMU. So far its working pretty well but im having some issues with the auto trans, torque reduction requests I think as the ECU is pulling mad timing during shifts and it makes the whole car buck and shudder since I retarded the timing a bit to reduce some pinging I had. Feel free to ask any questions you want and or let me know how to make the stock electronics cope with boost better! Oh and I almost forgot we are entering this car in the 24 hours of lemons this year as "The Red Baron" we plan on adding some tri-plane wings and perhaps a paintball gun or two in the front.

    Thanks,
    Derek

    Pics!

    Re: Supercharged Lebaron-24 hours of lemons

    Since I forgot to mention it in the post we do need to upgrade the brakes and suspension still in order to go round those natural enemies of american cars, corners. Brakes we can spend a few bucks on(not much we are actually poor, thus racing in lemons) and the suspension upgrades have to be like less then 150 bucks, total. If anybody has an ideas of where to go for all that and also any ideas on how to stiffen up our motor mounts as we will probably rip all of the current ones right out.

    Well teh cheap way is to fill the mounts with windshield urethane adhesive... higher rate coils for the front, methinks pull some from a windstar van at a cheap yard and then cut them so it's not a 3" lift. Vigo was mentioning something about drilling shocks/struts and refilling the oil, so thick stuff in what you've got might work. For the back if you don't find any other ideas, you could put in two rubber coil assisters and then cut some off to bring it down again, but that will be rather solid.

    Dunno if anyone's tried case hardening swaybars, but I'd figure on doing something like digging a long fire trench, filling it with free firewood, getting it going good, throwing the swaybar on top, then covering it over with metal sheets to leave just the ends open and force feeding it air with a box fan or something.

    Looks good! Have you thought about a Greddy emange (Blue)? It only works for high imp injectors, which you have in there already. I seen one in the forsale ad's on here yesterday.

    Re: Supercharged Lebaron-24 hours of lemons

    Lemons is alot of fun!

    What I've learned so far in the two races we've run.

    Reliability trumps speed.

    Braking and cornering are more important than power. Especially if you do whatever you can to make the car as light as possible.

    Re: Supercharged Lebaron-24 hours of lemons

    If you can get some complete srt4 front struts in good condition for really cheap thats a fairly easy front suspension upgrade. Springs are about 70% stiffer than stock.

    Ive welded plates onto the rear axles to box them in on several cars, that is a cheap rear sway bar.

    If you can find some used jeep cherokee front coil springs from a lift kit (or maybe even stockers) and cut about half the length off them you should have a super stiff spring that fits in the rear perches.

    If you're going to have real traction on the back you NEED to reinforce the track bar, they bend like crazy. Since i have gone through a bunch of parts car what ive done is take another stock track bar, cut the bushing ends off, and weld it upside down to the first one to box it .

    I have pictures of all this stuff somewhere if you need em.

    Dont push the red button.You hear me?

    Re: Supercharged Lebaron-24 hours of lemons

    I have a soon to be 3.8 powered 94GTC, and can tell you that a 6 point roll bar that tied the front and rear together will be far more noticable than any thing else you can do. You need to tie the rear shock towers together and then triangulate the front shock towers to the firewall also. If you can tie the subframes together that would also help. I have high rate lowering springs and a 1 1/4" front bar, and although it handels fairly well, if you hit any bumps when cornering, you can hear the body flexing. I have minivan brakes on mine on the front. For the trans you could try an older, tcm, as they started the torque managment, I think in 95. If you can find an older tcm with the o/d lockout button that would be the best. Have fun and keep us informed.

    Re: Supercharged Lebaron-24 hours of lemons

    Thanks for the tips, Ive heard about refilling the shocks with thicker oil from some lemoners before that was on the list of stuff to do, we figured we would cut the stock springs first and see what we got but they do seem a might soft. We actually managed to dig up a manual lebaron v6 in our local pick a part and promptly stripped it of everything needed to convert ours to 5 speed. What are the biggest brakes that will bolt up that we might stand a chance of actually finding(the v6 manual was lucky enough!). Right now its an LX so its drum rear and what looks to be awfully small fronts, though the wheels appear to be stock and are 15" which if I have been reading correctly would mean they were the larger of the two options? I mostly need a caliper that I can fit some big aggressive pads in more then big rotors as I could give a crap if they warp but if we run out of pads bad things happen. A full roll cage is mandatory and we will of course be doing what we can to make it structural . Also in winning on distance reliability may trump speed but we are in it for the lulz and just to have a good time more then go for the overall win. Though there isnt much reason why the 6g72 bottom end would break under 8 psi, we are not exactly going for record horsepower. In another random note I have a car full of parts, some of which are quite decent(top motor is new, so is some of the A/C system which still works great for example). If anybody needs parts for their cars let me know I plan on selling everything at token prices, just need to make our 650 purchase price back in sales. Even if you dont want the parts buy something anyway so we can be legal to race

    Re: Supercharged Lebaron-24 hours of lemons

    Measure your front rotors to be sure. The largest brake setup you can get from the junkyard has 11.25" rotors and if yours dont measure that you dont have them.

    Since you have a late model car it is pretty easy to get those brakes on there. If your junkyard has any 91-93 daytonas i would check those first as they seemed to get them almost as a crapshoot regardless of trim level. If you do find them, you would need the caliper, caliper bracket that bolts to spindle, and the rotor. You may want to take a pic of your existing caliper with your phone or something and take it with you because you MIGHT already have the same caliper and then you would just need the caliper brackets and rotors.

    If you dont have late-year daytonas, i would just go for any long wheel base 91-95 caravan/voyager. They have the same brakes but a 5x114.3 bolt pattern. So you would get the caliper and caliper bracket, and just buy the 5x100 pattern rotors from a parts store for $20-30 each.

    those 11" brakes DID come on 91-up lebaron GTCs i believe, but those are even harder to find than the daytonas. They also came on spirit r/ts but if you see one of those in the junkyard you better be prepared to pull the whole drivetrain out because its worth a lot more than they'll charge you..

    There is a rear 11.25" vented disc brake setup. Honestly i wouldnt bother going out of your way to find it unless you just happen to see it. All the cars that had the 11" front will have the 11" rear. The vans always had drum rear so dont bother with them. If you do find a car with the 11" brakes i would get the proportioning valve too.

    Also, cars with the 4-wheel disc setup had a master cylinder with a 24mm bore vs 21mm for most of the disc/drum cars. The master cylinder will have either a 1 or 4 cast into the front of it under the reservoir to tell you this. Your car may already have the 24.

    ---------- Post added at 12:26 PM ---------- Previous post was at 12:19 PM ----------

    If you're swapping to 5spd you'll want to weld on the bracket for the 4th mount that is used on 5spd cars. Do it while the trans is out or you'll have to drop the k-frame.


    We have a member on this forum who makes and sells this bracket cheaply to save you time if you dont want to make it.
    http://polybushings.com/pages/moparubrkt.html

    There is a small chance you MAY already have this bracket on your k-frame so i would check.

    I have also made this bracket out of some pieces i cut out of a truck bumper if you want to do something like that.

    Well you could find some flared flowerpots, (Nice rolled edge) set those in the airdam at each bottom corner, then clamp dryerhose to the back of them to make brake cooling ducts, if you can't find the cheap/good option. Use detergent bottles or something for the other end for a rectangular nozzle. Immobilise everything with plenty of zipties though so it won't rattle off.

    Re: Supercharged Lebaron-24 hours of lemons

    Well since i already wrote this out for someone ill post it here for the OP too.

    About the suspension stuff i mentioned.
    http://i279.photobucket.com/albums/k...02368Large.jpg
    http://i279.photobucket.com/albums/k...02371Large.jpg
    ^double track bar.

    ^Plate to box in axle for rear sway.

    http://i279.photobucket.com/albums/k...03131Large.jpg
    Once you cut a rear spring (stock, cherokee, etc) the end is uneven. Depending on how you rotate the spring in the car, you can get a small adjustability in ride height/weight jacking. Putting the cut end at the front raises, putting it at the back lowers.

    http://i279.photobucket.com/albums/k...7/DSC05274.jpg
    You can use neon srt4 front struts and springs either with the k-car strut mount or the neon strut mount. This picture is with the k-car mount.

    http://i279.photobucket.com/albums/k...7/DSC05273.jpg
    The k-car strut mount requires modifying the strut shaft.

    http://i279.photobucket.com/albums/k...03696Large.jpg
    http://i279.photobucket.com/albums/k...03699Large.jpg
    using the neon strut mount requires redrilling the strut tower with a 3.5" hole saw and redrilling the bolt pattern.

    Re: Supercharged Lebaron-24 hours of lemons

    My spindles are from a 92 minivan, with 11 1/4" rotors. I got by large discs off of a Daytona along with the prop valve. I am putting stock springs back on mine next week, but I don't know if I am ready to sell the lowered springs just yet. They are just too stiff for a vert.

    Re: Supercharged Lebaron-24 hours of lemons

    We will be fine on that end, the car is getting a full weld in cage as per Lemons safety requirements. Our chassis rigidity should be well in excess of a street coupe by the time its done. Its all good though we couldnt afford to pay more then like 25 bucks for the springs which is very lowball so ill probably just go try and junkyard a set and cut em down.

    A while back i heard something about the v6 taurus sho front springs fitting our stock spring perches and they were supposed to be ~220lb/in. Stock is right around 100.

    The cage will be huge. Like I said, brace between the rear shocks also. This looks like about the most fun that could be had racing. From what I have read, the most important thing is the car still running at the end!
