Keep us posted. Since you have a fuel pressure guage you might just plug the existing pump back in and see if things improve. Right now your cummins pump is trying to drag fuel thru a pump that's not pumping (read: "big-assed restriction"). So long as the pressure stays below the VE's leak threshold, and above the starvepoint, you're going to be OK

I guarantee if you ask around, someone in florida has a set of timing tools to set the timing. it only takes about an hour in they take their time so someone shouldnt charge you much to set the timing on it.

Hey man first off GREAT JOB!!! Second, if you remove the factory in tank fuel pump have you thought of using a FASS System? Then you'll never have fuel issues....:tu:
|
Got a squeeking pully driving me nuts but here is the vid!!

Very nice there is a ton of room height wise (I know OBS Fords are tight that way).There was much talk about the clutch not holding the power but how about the frame desighned for 400 lbs of TQ now having over 800.Especialy with the angles having that much lift.Thats not a concern of yours?

As far as the clutch impressed so far just a bit grippy |
Great Job man. that is such a clean install. you are very tallented for sure.

That thing looks factory (HINT HINT NISSAN) You did an excellent job:tu::c: If you need someone to put it through its paces and find out what it will do, just let me know:rocking: Since I live in the mountains I can really test it for you:w2:

NO ONE here in Pensacola, Fl does the timing on the Cummins except pin timing. So I guess I will have to suck it up and spend the money unless someone on here lives nearby and has the tools.

ok guys,
I drove the truck yesterday and it ran fine except when you punch it you sitting still it puffs a little white smoke and pops a little. First thing that comes to mind is slipped timing, but the fuel pressure is 15 PSI at idol and if you bring it up slow it goes to 23-25. If you stab it it goes from 15 down to 10 then slowly back up. I have not wired the pump in the fuel tank yet could this be the problem, starving it for fuel? Thanks fof the help in advance! |

the fuel pressure is too low. the P-7100 pump likes 30-45PSI especially with larger injectors. get an Airdog AD150 and it comes with 1/2" lines and you won't look back. I might just take you up on the offer for timing! I have the fuel pressure idling between 12-15 PSI but when you go through the gears it pegs out the 35psi. guage. It still pops a little when I get on it hard, I really think it's the timing. |
that still may be a little low at idle, mine will have 40-45psi once i get my junk back together.
if it is popping at a higher RPM it very well may be timing. did you install the governor springs yet? 3KGSK will wake up a stock truck and 4KGSK helps with added fueling mods as it allows fueling over the entire usable rpm band even if you only turn 3200 it will fuel until you let off at 3200. the 3K fuels until around 2700 and the 4K will fuel to about 3600 or so depending on the spring preload. remember that anything over 3200 or so WILL require atleast 60# valve springs, and with timing, injectors and a nice new turbo i'd look at the bare min. studs but o-ring the head to have a little bit of insurance..... |

depending on the motor you are in the 12-14* range IF the gears were put on in the correct position. using a dial indicator is the only way to know exactly where the timing is.

IIRC someone on here purchased that kit and the gauge was measuring in inches. all the instructions and charts for setting timing uses millimeters..... just saying.... post up in the price quote forum here and see what some of the sponsors here can do for you with the timing kit.

Ive been thinking about the same conversion for a while, im glad somebody finally did it! What did you do as far as motor mounts?

awesome! does it sit down quite a bit between the frame rails? it looks like it sits quite a bit lower than the vk56 and i know the cummins is by far a taller motor than the stock motor.

ya i didnt plan on running the stock ifs. i was planning on a dana 60 like yours with a dana 80 single wheel conversion.

thats good thinking, im not going to have that much lift. i guess the 3" body lift for sure so i can fit the motor but i would prob only go 2 more inches in the front and thats about it. i plan on hauling a gooseneck so i cant go very high. how long did this whole project take you?

wow! did you work on it full time?

in terms of gauges and stuff? cuz a 12v doesnt require much wiring. i was thinking possibly a 24v. what are your thoughts on that? would it be too much of a pain in the a$$?

Ok guys here are a few pics of the truck now. I fitted the Dodge Cluster in the dash, and took a few exterior pics.

Nice!!!!

Nice!! was it pretty much just cutting and splicing wires or was it more complicated than that?

I cant see me wasting my time with a foreign truck like that, personally I wish they would have all never been built :argh:, although yours did turn out very bad ass
|
I've never seen a TITAN like yours:tu::tu::yeah:
|
Now I feel like a slacker doin the ford conversion like most guys, very nice job. I like the gauge setup, looks like it's always been there. I wouldn't let the clutch worry you, I drive a 1850 ftLB pete and the clutch discs look just like yours, except there's two of them. The first time I changed a clutch on a big truck I could't believe they hold up, and I've had them last over 800k!

that is bad! i work for nissan's heavy equipment devision and get an awesome deal on new trucks, makes me think :humm:
