Well I finally got the bal#s to shower down on it the other day and needless to say it has a LOT more power than the Titan motor! I was in in third gear when I hit it and ended up with a sheared 1410 u joint, twisted D-shaft and 2 busted springs on the driver side! I since replaced the springs, added two for a total of 5. Made my 2" x .250 wall DOM Traction Bars with 1 1/4" Creeper joints, Thicker Dshaft with Yukon 4340 Joints and a set of goodyear bags. Since then no problems exept the tranny sounds like its going to come apart. The frame is doing great with the new found power. I am still needing to regear from the 3.73 to 4.56 and then a dyno!

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.....

I have the 3K gov springs, New BW S300 Turbo, 370 Non-Marine injectors, 4" downpipe to a 5" exhaust. And I pin timmed it, but I am 99% sure it slipped a little or I didn't get it right on the money!

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.

I had to replace the front timing cover so I put the gears back, I did make sure to line the o in between the oo on the crank and camshaft. As for the pump, it was close! I'll get up with you when I get back in town in a few weeks. I found a guage set online for $149 through pure diesel power. It's not snap-on but looks to be good quality.

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.

I'm glad you told me that! I didn't realize it was measuring in inches. With everything elso going on while timing I really dont need to be figuring out a conversion factor as well!

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?
