3 days and counting....
 

Thanks all... I'm excited now. It's taken so long that I literally just gave up on a date so I wouldn't be disappointed.

I did tell him I didn't care how long it took as long as it was right... there were no exceptions to that rule.

Guess I should be more explicit next time....lol.

I figure with a 3000 mile test drive, it should be ready to go.... any issues surely would show up by then.

Re: Duramax conversion update....
 

I guess its been so long I forgot the details of the build but what year truck did the Dmax you used come from? Does it utilize stock intake and somewhat of a stock exhaust? (from the dmax truck, not stock h2) Or is there some sort of custom exhaust setup on it?

I can't wait to see photos and hear it! Way to take a rare and unique truck and make it even more rare and unique :excited:

I think most of us on this forum would cry after watching that video :giggling:

Re: Duramax conversion update....
 

I bought a 2007.5 Duramax LBZ engine and allision trans with 44K miles on it. (it's as close as I could find to what was on my H2...high 40's)

I spent 3K on a built allison trans so I could add the PPE tune. The tune I chose is the middle of the road... an add'l 225HP and 360FTLBS of torque.

I didn't do the power increase as much for power as much as gas mileage. As you know, the more you lean out a diesel, the better and more efficient it runs. I've read of guys getting 20-26 mpg tuning their setup. If I can break 20, I'll be thrilled to death.

I bought a cold air intake and left the exhaust stock off the 2500. I didn't want some obnoxious huge exhaust blowing black smoke everywhere.

One more day...
 

Got a phone call from Travis today earlier and then tonight as he was approaching Nashville.

Should easy be here tomorrow.

So far, no issues except a plastic trim came off the back of the bed (around the rear sliding glass)

I see no reason why I'm not driving it this weekend.

Let's see some Mini pics in the meantime!!!

Re: Duramax conversion update....
 

I bought some Recaro JCW seats from England. I installed harnesses in them.



So after I installed the seats, I had some seats made for the rear.

Re: Duramax conversion update....
 

LOL, I will today

I got it back late and it was dark. I didn't go to bed last night till about 3am and here at 7am, I'm going to the shop to work on the truck.

Here's a few things I have to do.

Charge AC

Alignment

Install new air horns.

Put tonneau cover back on.

Take pics.

That's basically it. I cleared some codes (the larger tires with the 2500 ECM made the ABS lights go on) by installing the PPE tune.

I'll post more later.

You're a patient man!

Re: Duramax conversion update....
 

Sorry guys, I didn't go to bed till almost 3am and I was at the shop at 7am to start working on the truck.

I started with pulling the old air train horn and install a new one. I got everything mounted but didn't have time to wire it up.

I fixed a few trim pieces that either came off or the two-sided tape wasn't holding.

I still have a few things to do like adjust the frt bumper. (being in the bodyshop business, that's the only thing that bugs me)

Other than that, I charged the AC and washed the truck.


I programmed the PPE tuner to only the third level (though I have 5-6'ish) which added like 160HP/240TQ and reprogrammed the tire size/gear ratio.

Even after I did, I kept getting a ABS error. Travis never did any programming on it so I waited until I got the truck back to do it myself.

As told by Travis, chances are I'd still have the light on because for some reason the ECM doesn't like to work with 4.56 gears (don't understand, don't get it)

So after several tries, I got the bright idea to set the tuner for the stock 4.10s with the stock 33" tall tire.

It worked.


I drove around all day and this is what my average was.



A little tweaking and getting familiar with everything, I'll get it set up soon enough.



By the way, it's really wierd to punch the gas rolling 15-20mph and hearing the tires start to spin.

I'll post pics tomorrow.
