Anyone done the diesel conversion?

[johndjmix1]

Just curious if anyone on here has actually parted with the large sum of cash and done the Duramax conversion. A few companies do the conversions, which did you use?

Too much $$$ for me but wondering if people are happy with it.

I have seen two if them. A fairly local shop does them, and they have a lot of d-maxes sitting around, so its not always as expensve as one would think.... If they are not busy, its reasonable. The issue as I see it, is not putting the diesel in the engine compartment, its about fitting in the mamoth allison that its mated to..........

You got that right ,i belive you need to massage the trans tunel quite a bit. I have had the Allison out of my 2005 chevy ext cab 4x4 Dmax (LLY) 2500 truck to put a Suncoast IV and converter in it and it is HUGE and very heavy . if you put a heavy tune 100 hp or more you will fry the alli,and I did at 25000 miles .with the Suncoast that won't be a problem again ,rear tires are the problem .

LOL... Suncoast makes a good product..... Everytime I hear someone talk about them, It makes me think about Joe Webb and his death, and how horrible it had to be for his friend to have to drag him back on the boat... Last I heard they still think it was a heart attack as they came up....

I know the LLY is sort of a head headed stepchild and has always been significantly lowwer on power than the LB7 or LBZ... But some of the guys have got the EFI Live programs kickin for it... Lots of fun, but your always chasing a weak component!

[IRA51]

when the LLY came out there wasn't a lot of programeing for it ,now there is and there guys in California McRat for one tht have broke into the 11's on #2 alone,from what I hear . the LB7 was a good motor ,but the design had major flaws such as fuel injectors under the valve covers so when they failed your crank case filled with fule and trashed the engine .the Lbz is the best of the bunch and if i'm still alive and kickin in 2009 when they change to the new frame I'll get one .though I don't like the Idea of a particulate trap that needs cleaning and with a tune it may be a problem. and yes EfI live is the hot ticket . at this time I belive the LLY can hold it's own power wise wit a LB7 . the LLY and the LBZ are very close in design the LBZ has less compression and a slightly beefer block . my LLY has been flawless so far and I drive it like I stole it ,I can tow a 10000 lb toy hauler up sunset point on the way to flagstaff in 115 degree heat and not over heat . It has been the best truck I have ever owned .

Be careful. This guy is a scam artist. He has already scamed many Hummer owners! He probably has stolen a good 100K plus. Check out the following link. His real name is posibly Blake Mastin or Blake Andrew Sundvor. Check out the following link: http://www.alldieselmotorsports.com/...hp/t-2918.html

I was asked to post this by some concerned vendors/members.
Dear Dealer Network,



It has come to my attention that we have a very unethical/immoral individual trying to represent our product. This individual has a sentencing date in Jefferson County on 4-16-07 @ 1:15 for 3 charges/counts of theft Felony 3 and Felony 4 as well as a violation of bail bond conditions. The prosecutor is Christopher T. Brousseau.



This individual has caused many problems with companies, along with friends of mine that we respect and do business with. He seems to have a history of promising the world and delivering nothing for free product. He has also misused customer credit cards.



I am strongly encouraging our dealer network and any dealers they sell to not to conduct any business with him. Please, do not sell any FASS products to him. We build a high quality piece of equipment. The perception of our quality depends upon the quality of the dealers? presentation.



The individuals name is Blake Andrew Sundvor and goes by Blake Mastin. The company he is using now is Max Psi Performance or as see on the internet as maxpsiperformance.com.





Please pass this on throughout the companies you may do business with.



Have a great day,

Funny thing is every vendor I know in the diesel performance world has had similar things to say about this guy.

In my business I see most everyone face to face. Makes a big difference.

I did mine myself. Got a forklift threw the body off, rolled the frame in my shop and went to yankin. Fairly easy. Predator and the other shops who do this are about 99% full of ****. The allison and motor fit fine. Its the wiring that will make you want to find jesus. I spent 3 weeks and mapped it all out. If you have patience alldatadiy.com and a tech 2. Not to bad. Id save my 40k or 30k and do it yourself. I have everything to do it thrown up on ebay for those of you feeling lucky and would like to keep you ahole intact.

damn, id love to see some more detailed pictures on that.

Got any more pics of this build? just Curious!

I will take some more of the dmax whenever i get all the twigs and mud from the lake out of the engine compartment.

[RCKSTR]

Did this guy dissapear off the planet? Never did post any other pics or info, emailed him a few times, no response..

[RCKSTR]

No one has any additional info on the swap? Im going to start a thread for it step by step when I start, the wiring is the only thing holding me back. If you talk to predator,mash, or any other place that does it, they say it will make you want to find jesus. If you talk to a guy that has actually done it, they say its not that bad. I dont see how they could pull off a conversion in 4 days if it is really that bad. Im posotive they are just trying to scare us so we dont try it ourselves and pay them rediculous amounts of money for them to do it.

I'm sure they could do it but I'd count on a few weeks at least.

Predator does a lot of conversions. They've even got a contract with the government to upgrade the border patrol H1's to Duramax engines from the 6.5 so they have a high turnover rate and lots of experience.

Could they do it within a week? Call up and ask, I imagine a base exchange is custom shafts [already made and in stock,] custom harness, and custom crossmembers and body lift ready to go.

[OrangeCrush]

Gonna cleanup this thread. I'm guilty as others are. Deleting all impertinent content....

Anyone have any helpful answers to the OP's original question, then respond... the rest of us will keep our opinion's to ourselves.

Sorry, I wasn't able to scan if you've commented. How much does it cost again? I would like to compare prices. Thanks!
