    24v 3.0 Duster progress log

    Well, if you haven't lurked in the 3.0 section or been naughty and gone perusing on TD... heres my project.

    If you want to go over to the dark side and read the original thread, it is HERE

    otherwise, here is a quick synopsis:

    Started about 3 years ago when the 1992 Sundance Duster 3.0 5 speed i bought for $80 decided to die after busting through a 2'x3' snowbank at about 60mph. (suspect now that the heads cracked) After attempting to do an upper gasket kit to revive the motor (which didn't work) i decided to look for alternatives.

    After much googling and searching i found that the 24v 3.0 in the 00-05 eclipses was nearly identical i went looking for such a motor. Found a motor for $200 about 20 minutes from my uncle's house (he has a F350 turbo diesel dually flatbed truck) and said "here's a 6-pack...go fetch?"

    once I got the motor I dove right in. (mind you, most of this is before i got into the Turbo dodge world) was able to pull the old motor and trans, mate the new motor to the trans. and fab up a passenger side motor mount. After the motor was physically installed, i had to install and wire the Megasquirt.

    While i got everything installed right, it took me about a year off and on to finally get the car to run. Initial attempts using the 24v distributor met in complete failure. (in retrospect, i may be able to get it to work now, but i did not have the requisite experience or information then). It took me so long because i had the car towed with me from CT to school in south western NY and worked on it when i had time. I got stuck when a misalignment between the trans and motor chewed up the ring gear on the flywheel.

    That 2nd summer consisted of installing a 4 puck ceramic clutch and HD PP from FWDPerf and an OBX LSD. I also installed an EDIS-6 module with GM coilpacks and was able to start the car on spring break of 07. Took the car to school the next year and was able to go to the track for the first time. Ran 1 14.96@93mph best at NYIRP.

    Since then I have fried the 4-puck, killed an OBX (case bolts failed taking the OBX out necessitating a transmission rebuild) blown the oil sender apart spinning two rod bearings, and many other issues. I now have a new OBX, a purple PP and 6-puck clutch from TU, a fidanza Aluminum flywheel, a better tune, slicks, launch control/flatshift, and other mods i can't think of.

    Plans at the moment are for an M90 supercharger, intercooled with 390cc injectors. and eventually a caravan AWD system mated to the A543 (once we figure that one out lol). I have run a PB this season of 14.712@92.99mph and am looking to beat that at Turbopalooza on nov 7th.

    Its actually been figured out, check out the AWD thread in the trans section... But i dunno about pto to 3.0 block issues. I dont think anyone has tried that combo yet.

    You'll definitely blow past 14.7 with slicks, launch control, and flatshift.

    Glad to see you're posting over here.

    Me too

    You dont need the whole thread.. nobody will read the old stuff unless they want to do the 24v thing too, and lets face it there's barely any 12 valvers here, let alone people wanting to swap to 24v.

    Keep this thread up to date and you're all good

    Re: 24v 3.0 Duster progress log

    Well, not too much going on lately. Made it down to Turbopalooza but only for the after party at ken's. "Lucy" died on me on the way to the track when one of the wires to teh MS that drives one bank of injectors and 4 of the 5 grounds to the MS broke off the DB-37 connector at the MS. Had to buy a soldering Iron and use NMW2006's inverter to get her back up and working. couple that with assembling NMW2006's car sat morning, i got there at 4:50 so no runs for me (wanted to try launch control on the slicks to cut a better 60'...)

    Once re-soldered, my tune went to crap as well. had to up my req. fuel by almost 3 whole numbers and im in the process of re-tuning the fuel table. Not sure why re-soldering the grounds and driver wire would cause the tune to go so out of whack though....

    NMW2006 also noticed that im burning oil on moderate to heavy acceleration (my mystery oil consumption has been found!) im hoping its not the rings, and i started with replacing the PCV valve. I'm tempted to try some MMO in the cylinders to see if its the rings but IIRC earlier this summer when i did a compression test, all the #s were good... any input, advice or whatnot on that?

    I am tempted to try the auto-rx that Lookin has mentioned, but im too broke to buy that at the moment.

    well, if you can get your hands on a leakdown tester it might tell you a bit more than the compression test.

    im excited to see what you get from the launch control (whenever you get there), should be fun!

    Re: 24v 3.0 Duster progress log

    well, i figured out some of my issues:
    I replaced the o2 sensor and that fixed the sensor reading. also found out my ign connection was accidentally grounded and i've been running limp home EDIS timing of 10* since i put the new relay board in (and ran a 14.712 on 10* timing lol) car runs like a raped ape now

    Re: 24v 3.0 Duster progress log

    in thinking about the spark issue, I should say im not 100% sure i ran the 14.7 on 10*. I think i may have fixed a ground issue when my car died heading to turbopalooza that caused my spark request to go to ground and EDIS defaulted to 10*...*shrug* im just happy the power and most likely the gas mileage is back

    Re: 24v 3.0 Duster progress log

    Glad you're still updating. Im leaning more and more towards a dohc 3.0 in my minivan these days. Funny because i started a turbo 2.5 swap and have been just a fuel pump away from finishing that since like September, and i have all the parts for a sohc 3.0 build, and im jumping 2 or 3 swaps ahead and scheming for dohc. lol.

    Thanks. Good luck whichever way you go though (personally i think the 3.0 has a TON of potential though)

    Re: 24v 3.0 Duster progress log

    Well, National Trails is slated to open Sunday 3/28 Been prepping "Lucy" for the first test and tune of the year. Launch control/flatshift is wired up and ready to go. Slicks are also prepped. Hopefully I'll be able to beat my 14.712 from last season with a proper launch...

    I'm also thinking of running the T-100 weds. night brackets this year. Not that i expect to win or anything, but it would be good practice.

    Still trying to save to do the M90 installation, but working for a temp company isn't conducive to making good money lol

    Also, going to look into having a bodyshop fix the rocker rust on "Lucy"...we'll see how bad the quote is lol

    Well, i didn't get to go to the test and tune on 3/28 or the next one.

    I did go to the first T-100 weds night and placed 2nd in class Z) (too bad points don't start until may) I got the launch control and slicks in the ballpark. 4800prm limiter, only scrubbing the slicks briefly and 22psi in the slicks. still bogs a tad on launch but not nearly as bad as before. Ran a best time of 14.705 but had to let out so i wouldn't break out...it was a 14.6 or a 14.5 run if i coulda ran it out the back door... Well see how it goes this season and i hope to bring my times down a fair bit

    Re: 24v 3.0 Duster progress log

    Are you not launching it very hard, then? Most people with manuals and slicks are doing 1.7-1.9. Just curious!

    Re: 24v 3.0 Duster progress log

    I'm dropping the clutch from 4800rpm full throttle (Launch control on the MS ) I think whats killing me is either too sticky tires or the aluminum flywheel at the moment. I stil have some things i can do to the setup to minimize bog i think

    Try taking the limiter up. In fact, take it up until you spin horribly.

    Re: 24v 3.0 Duster progress log

    I'll see what i can do with that... i think if i go too high it will interfere with the flatshift. gotta check the forums and all.
