LB7: The Rebuild, Ch.2 -- Building slowly
- Thread starter TheBac
- Start date
Congrats! I still think that smiley face is the funniest thing I have seen in a long time. I wonder how many duramaxes have that in them? Probably just yours. At least you know your truck wasn't built on a Monday! 
freeway @ 72mph, 2250rpm, oil pressure is ~65lbs, coolant temp normal (192 on gauge?) egt ranges from 600* to 750*, excellent acceleration up to 90mph (I had to test it), OAT 85*.
hot idle oil pressure is ~28lbs, egt right around 220*, idle smoothed out too.
Motor mounts add a bit of vibration only when initially accellerating from a stop and just as the truck shuts off. Otherwise you'd never notice.
Those 30% injects sure add a bit of power....its like driving an LBZ now.

Figured Id update some things:
1) 7500 miles on the motor, no new sounds or problems. I think that odd noise I was hearing was a combination of injector knock and the exhaust flowing thru the manifolds/uppipes.
2) Oil pressure is still 80-90lbs at cold start, 60 @ 2000rpm, and 25-30psi at hot idle. Me like.
3) Fuel mileage is down to about 16mpg overall. I attribute that to the injectors and me not knowing how to write a tune that optimizes them.
4) Found my receipts, and the grand total for the build, including injectors/uppipes/manifolds, all machining and fluids was $5025.29. Kept myself on budget.
5) Last but not least, the motor obviously ran better at the track. I look forward to the 2011 race season. Got a wastegate to install and some other tweaks to do.

Nope. I like my stock turbo. Next addition will be Trent's S475/stock twin setup or something similar.
Probably will need a new CP3 after this year, too. Stocker is getting tired.
Saving funds for 2012 as we speak.

Keep going.
More like $2500. I figure a totally stock rebuild would have cost me about $2100, and thats with the refreshed heads.
Yea I posted then thought about the studs, motor mounts, ect. . I'm hoping when the time comes I won't break the bank considering I already have studs, injectors, ect, ect.

Oh hell....forgot about the motormounts. Gotta go add that into the total. Shoot.
No studs..I went with bolts. The only extras I did were the injectors, uppipes/manifolds, cutting the pistons and balancing the crank.

Thats great Tom, I must have been living under a rock I never knew you were back kickin already. Congrats
Tom I'm glad someone can stay with the budget they want to. LOL. Hope to run into you while I'm up in the mitten in the next week.
X2 i havent seen this thread since it started, Seems like you had good luck with your build. This thread is definatly a good read and will come in usefull :thumb:
