spacers?

lunati397

i have 2 inch fronts and a 4th gen rear might need a 1.5 rear also

lunati397

I looked and havent seen these on a thirdgen yet

lunati397

scored a set of coil overs today at a swap meet for 10 bucks I need to get different springs for the right spring rate but good deal

dctrouant1995

i cant tell but the wheels you got, are they the same ones that are on the car behind the wheels?

lunati397

yeah the ones on the car are chrome now these were taken off because two have curb rash but i got the set for 400 so im not complaining and I do powdercoating so I can smooth it out and recoat the wheels

When you're ready to dial in the Durabux, you can get it done with some off the shelf tuners. And, no, I'm not talking Hyperchiptechdiablobanks... Look at PPE. I'm running their Xclerator in my 06 LBZ, and that thing is scary fast for an 8,000 lb truck. Of course, if you know what you're doing, and live by the pyro, you can run EFIlive. I think that'll be my next step as well. You'll find that you catch some sort of "more power" virus the Durabux, and suddenly 600 HP is not enough.

I am a little worried about the 4L80 idea though. I think you'll be glazing the clutches pretty quick. The 6.6 makes an incredible amount of torque at 2,500 RPM. You'll be over 800 lb*ft at that point if you get your tune dialed in. Idk what kind of clutch holding power you'll get out of the 4L80 at the RPM.

Speaking of low RPM's... what do you plan to run for a final drive? My truck is at 1,700 RPM, give or take at 70 MPH with the 6 speed Ally. If I run in 5th or 4th, my mileage goes to crap.

Anyways, the build looks awesome. Can't wait to see it done. Would love to see it at the track one day. Best of luck.

lunati397

im going to use efi live and distance tuning where I log then send off and get a tune with the V2 and I realize the hunger for more power but thats no different with gas or diesel you will always want more 600 range I can get away with a stock bottom ill start building a new block once this is all good and done for more

the 80 will be fine im going with a spragless 4th and red clutch same that would be used in a allison build and it will have a good convertor built for well over what I plan making

still need to figure out the final drive I might see how the 3.42s do and go from there but you have to remember your truck is 8k brick with a 32 to 33 inch tire ill have a 27.5 tire so thats all up in the air now still I need to get farther along to know what will work best but the final rearend will be a fab9

I guess I was concerned about developing enough line pressure at low RPM to prevent the clutches from slipping and chattering. That would be the biggest difference between the behavior of the 4L80 and the Ally.

I found a breakdown of same year transmission ratios…

One thing that I would like to point out is that in 2006 the OE tire size on these truck was 245/75R16E. That’s a 30.5” tire. FWIW.

Overall, it seems that you will be leaving nothing to chance.

lunati397

you are right about there being enough line pressure because it wont be spinning high enough but I can assure myself with ajusting the pressure and the 80s do produce low line pressure and have been behind the duramax from the factory in all the 6.6 dmax conversion vans stock to stock

what I will have to see is how it feels rather than rely on the numbers is the final drive I want to have the best well rounded car tq will make up for gearing but I dont want to be at a point where I trap at 132 and i redline at 132 and my top speed is 132 I go alot by feel more than numbers. like one motor I had was alot less powerful numbers wise than guys I raced but I would destroy them some of it was driving, weight, gears, hell the enviroment that I raced in there are alot of things that paper and numbers will not give me

**** with that torque you could get away with 2:73s or some 3:08s.

wanna sell those for what you got those rims for? i wouldnt mind taking those off your hands as i do powder coating aswell and it wouldnt be nothing for me to recoat them..

lunati397

lol they were a deal and they are rare being they were only on a few models so I might be holding on to them

they were gunmetal then painted and poorly painted too because where the curb rash is I can peel it off in flakes

Re coat them or polish them and sell for 4 times what I paid

87 "BlackBeast"

hows the swap comin? havent updated in awhile jus curious

lunati397

Im in san antonio for the next month for a class but will get on it when I get back in the time being I will be buying parts

85z28kid

iTrader: (7)

I'm first inline if you decide to get rid of them lol.

lunati397

Im going to use them just have to mini tub the rear and the tires are 345 35 r 19 DRs that are 404 a piece but its going to look mean

Now for some opinions I have a white car and I like chrome or polished aluminum but what color should I coat the rims if I decide to powdercoat instead of getting them chromes or polishing them

I am painting the car bright white with a blue pearl and the black parts will have a red pearl and the RS will be the R will look like a ice cube and the S will look like a the cube is on fire the motor will be accented with blue powdercoating either cobalt or a translucent over chrome powder

You took my dreams and are putting them into reality!!! I wanted to do this after college. Your mpg are going to be ridiculous!!! Hotrod mag published a 94 mustang with a duramax that runs 9's and hits 38 mpg. He also ran over two hundred in the standing mile. You chose an awesome engine to swap into a thirdgen. Diesels sound awesome and perform great. This world needs more of them. Thanks for taking on this project!!!

I get back home next week so there will be updates again I have some other projects that will have priority but ill be getting what I can done

Test fit new wheels build the K member and get the motor and trans in and start working wireing harness

Cray z28

I just bought 20x12 rears and 19x10 fronts.They are almost the same as the ones you have. They are for a 2011 corvette zr1

lunati397

the ones i got were off a 2011 grand sport those are one inch bigger keep up I will start fitting them soon I have a 4th gen rear already im thinking roll the fenders 1 inch spacer and mini tub and the nitto NT05R Drag radials 345/35/R19 rears and the 555r fronts around 275 wide

put down fresh asfault because the steam rollers will be coming

Cray z28

Yeah my rims are 20x12 19x10. The rears are 335-25-20....285-35-19. I am going to keep the stock body lines and tub it. Nice build. You are flying through it. Great job.

kmcn47

sub'd YOU CAN DO IT, we should have a thread like the COTM thread for the fastest and most powerful cars on the board

Richboll

I prefer Chevy in a Chevy but I'm up for this build. The curiosity factor is high and I want to see this through to completion. Keep up the good work.

Richboll

I'd go with cobalt blue on the wheels and maybe some colbalt blue highlights inside and on the car. This maintains the continuity of your engine theme.

Cray z28

Uhhhhhhhhh Richboll, Duramax's do go in chevy's!

Richboll

When you throw in the terms of Izuzu and diesel, they've never been in any Chevy I've ever owned and I've owned a lot of them from back in the day when anything from a small block fit on almost any other small block and ditto for the big blocks. That being said, I do find this an interesting swap and admire the efforts that are being done to make it work. And being an old drag racer, I'm anxious to see the end result. Maybe I'll be a convert.

lunati397

anything duramax NOW as in the past 2 years is 90 % GM they have been redesigning the duramax to exclude izuzu from the rights because toyota now owns a part of izuzu so to keep them from getting it they had to make it all GM

look up the 4.5 duramax that they were supposed to make thats an awsome motor same size and weight as a 350 and it got 30 plus mpg in a 1500 also made same power as a 6.6

Seafarer12

I am not much of an electronic diesel kind of guy but this should be interesting.

Richboll

OK so we are all on the same page with this. Let's see how it goes. Like I said before, some of us may become converts.

Seafarer12

I was mainly subscribing to the thread more than anything. Don't get me wrong I have wanted to do a 6.5 TD for a few years.

From WIki,
The Duramax is a General Motors diesel engine family for light- and medium duty trucks, designed by Isuzu. The 6.6-liter Duramax is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio. This engine was initially installed in 2001 model year Chevy and GMC trucks and has been an option since then in pickups, vans, and medium-duty trucks. In 2006, production at Moraine was reportedly limited to approximately 200,000 engines per year.[1] On May 9, 2007, DMAX announced the production of the 1,000,000th Duramax V-8 diesel at its Moraine facility.[1]

lunati397

well back to on topic I am back in town now but have another project that is priority over mine

Taking a V6 Auto 99 Firebird and making it a LS6 6 Speed
powdercoated and put the motor together yesterday

lunati397

got some key peices in for mine too got the remote oil filter kit and the tailshaft for the trans and I ordered the DOM to make the K Member so hopefully I will get the motor to fit and mount up in the car soon

but I am doing all the same stuff with the firebird

85z28kid

iTrader: (7)

That motor looks really good now! Hope to see that motor in soon. Do I hear making a few k members and selling them?

lunati397

thats the plan after I get this one designed and good and tested then maybe a production I am making sure to make very good jigs for easy reproduction

Seafarer12

Never owned a Diesel Chevy LUV?

Richboll

Nope, never owned any kind of diesel. I joined this forum because I thought this was about cars...Sorry about my ignorance 'SweetRevelation" but the closest I've even gotten to owning a truck is my 82 El camino.
I thought this might be an interesting thread to follow but personal attacks? because of something associated with Izuzu? count me out!

kmcn47

i think cobalt blue wheels would look bad on any color car

72vega

iTrader: (9)

maybe someone can tell me what an Isuzu Hombre or the I-series pickup was (lol sorry had to throw that out there.)

kmcn47

i'd love actual build updates, rather then arguing just me though

Seafarer12

Richboll, No insult intended. I am sorry if you took offence. I wont joke around with you anymore.

lunati397

working on it

Cray z28

Hey richboll don't leave. This site is about cars, badass cars, and creative minds that create these beauties from a twisted vision in their head. No insults just jabbing back and forth. Keep up the great work Lunati. I am close to mocking up the k member for my build as well.

lunati397

I spent all day yesterday with the plasma cutter and cut off torch making small manageable pieces of what was left of the donor truck I need the space back wife was tired of it and a long bed crew cab 2500hd is a big mother trucker

got it down to the frame and thats gone today
