Hulk Pm Or Email Me Your Number Again If You Do Not Mind

 

Hey Macet ,

Pm is sent !!

 

I am learning alot about how different this motor is from the 3.3L. For anyone else who chooses this motor. I have made friends with a guy on 4btswaps forum , he is a forum vendor over there, very knowledgeable and actually has the wiring harnesses I need to get this thing running as well as an inexpensive potentiometer that reuses my existing accelerator pedal ; his name is Lee Reiff ( great guy and very helpful ) !! reiffdiesel.com !!

I have really been struggling trying to get the accessories tracked down until I met a guy named Tom Hanley at Iowa Cummins ( very patient and unbelievably helpful ) who tracked down all the part #s needed for A/C and Power Steering ( I will post over next couple weeks all the parts I use ). He accomplished in 2 hours what 3 other dealers had not done in 6 weeks !! He informed me that I have to mount the engine higher in the frame and work around the Center Sump Oil Pan ( because trying to install a rear sump pan is an unbelievable P.I.T.A. that would incur some block modifications related to engine balancing ) !!

 

Can each of ya'll who have a running vehicle with the conversion tell me what RPM is the engine @ when you are at 55 or 65 in relation to your top gear! It appears I will be around 2100 @ 65 mph with my present gear and tire combo !! And I was trying to figure an approximate fuel economy; although I would be happy with 22 mpg, that is what my 07 Grand Cherokee gets with the Mercedes 3.0L Diesel !!

Also, did I understand somewhere in the last 900 some posts that someone has connections at Cummins to get a discount on factory parts ??? If so, PM me or email me harlow.hutchinson@***.net , $150 for exhaust elbow and clamp seemed kinda high and if you can hook me up with a cheaper price , I would appreciate it !!

 

I'm just under 1600 rpm at 55 mph and ~1850 at 65.

 

Thanks TDI,

anyone else ???? 3.3 sonoma, macet are yours similar ???

I received the stuff from Lee Reiff @ reiffdiesel.com set me up with a potentiometer , and the wiring harnesses I needed to move to the next step !! He also got me a 2 ft tall by 2 ft wide wiring diagram BLOW-UP ; so I don't go blind trying to read it !! The harnesses came off a 03 to 07 Dodge 5.9 Cummins and is a 50 pin !! This 50 pin harness coming out of the computer DOES NOT have to be Can-Bus, which will greatly simplify things !!

The wiring diagram from Cummins says it is for the QSB4.5L , QSB6.7L, QSC8.3L and QSL 9 and that they share the same CM850 ECM ; so , I doubt it will work on a QSB3.3L. Finding out what ECM is used will be the key to hooking to it !!

95z28a4, Lee may be able to assist you with your QSB harnesses also; just maybe !! Good Luck !!!

 

1500@55
1780@65
2050@75

 

i have a good spreadsheet i made for gear selections and speeds and such. i can email it to anyone that asks.

 

WOW, 3.3sonoma !! aren't you getting like 40 mpg ?? My hopes of 22 to 25 mpg may be attainable with room to spare !! If I stay around 65 mph !

My estimate of RPM is based off 4.10 gears and 35 inch tires and overdrive 0.79% should be approx 2100 rpm @ 65 mph !

Thank you !

 

Hey kriesel , I never turn down info so , please send your spread sheet to harlow.hutchinson@***.net !!

and thanks !

I called Lee at www.reiffdiesel.com today. He didn't have any partial harnesses he could sell me. The CM2150 ECM uses a 60 pin plug. He did tell me about an aftermarket crimper that can be used in place of the $275 Deutsch crimper. The crimper is a ProsKit CP-463 and costs ~$45. I ordered one tonight from http://www.proskit.com/cgi-bin/proskit/CP-463.html .

I modified the turbo oil drain / oil fill spout for frame rail clearance instead of purchasing the $120 Cummins piece. I cut off the fill cap and welded on a tubing cap I purchased on eBay for $4. Pictures are on my flickr site in my signature.

I also fabricated a block heater adapter for the same block heater Macet used for his YJ. Concept is the same as Macet's, but components are a little different. Pictures with descriptions are on my flickr site.

I am presently working with a guy in Texas on a hydroboost mounting plate / spacer to make the 2005 Suburban hydroboost a bolt-in to the ZJ. I trial fitted the prototype this evening. I'll have pictures and more information when I get the finished product.

After looking at the axle on my 1994 ZJ, I decided that it would be MUCH easier to have a completely assembled axle to take measurements from while fitting the brackets on the XJ Dana 44. So, I purchased a complete 1996 disc brake equipped ZJ Dana 35 from a local U-pullit salvage yard. I'll be cutting the brackets from this axle and welding them to my XJ Dana 44. The axle assembly was cheap. I figure that I can get my money back by selling the disc brakes and axle shafts on eBay.

The ZJ that I pulled the axle from had an OEM gas tank skid. My ZJ doesn't have one, so I purchased it for a whole $5.

I have decided that the nearly new 2006 Dodge Cummins intercooler that I have isn't going to fit in the Jeep without major modifications to both the intercooler AND the Jeep. My original plan was to cut the bottom 7 rows from the core and weld close the bottom of the tanks. Unfortunately, the intercooler is too wide to fit between the ZJ frame rails and so thick that I won't have room for an AC condenser. If you know anyone who needs one of these intercoolers, I'll sell it for what I have in it - $150 + shipping. After more research and emails and measuring I purchased a 1999-2004 Isuzu NPR intercooler. The intercooler is significantly smaller than the Dodge Cummins intercooler, but should still be more than large enough for the QSB3.3T. I think I'll have to modify the inlet and outlet tubes, but I have a welder friend who can weld alloys in his sleep. Relocating the inlet / outlet tube(s) shouldn't be a problem.


The dimensions of the Isuzu NPR intercooler are:

Width at widest point (from inlet to outlet) – 29”
Width at 9" from bottom - 25.5" (lower part of intercooler that must fit between frame rails)
Height (from top to bottom mounts) – 17”
Depth (incuding inlet/outlet tubes) – 4.5”
Inlet and Outlet tube diameters - 2.75”
Core thickness - 1.5"
Core width - 20"
Core height - 14"
Tank thickness - 1.75"
Distance between tubes - 23.75"
.

 

95z ,

I am glad my research was able to get you in touch with someone who was able to save you some money on your project !!

Sounds like you are making some great progress !

I ended up finding a 2005 Dodge Sprinter van intercooler on ebay for $91 .... it was a little too wide , but only 2 inches thick so, I trimmed the inner fender of the wrangler and made an adapter bracket to mount it to the radiator bolt holes using the Intercoolers existing mounting provisions!! I will eventually make some pieces to cover the holes and protect the intercooler from flying debris ! I'll add pictures of it mounted to the front clip to my flickr account if you would like to take a look !!



Due to the oil pan and the front axle proximity , I may end up with a hood scoop similar to TDIwyse. I am not adding more lift to my JEEP and will mount the engine as high on the frame rails as possible !!

 

Got the email thanks , that is a very useful spread sheet !! And it seems my " estimated guess " was within 50 rpm !! I hope it works out in reality the same way , 25 MPG could be attainable !
