I've been kind of quiet for the most part when it's come to my Duramax build. Figured I'd finally start a build thread on it. Back in October I had just finished installing new injectors and resealing the injector cups after one blew out from Truckfest. Was out test driving/hot rodding it and lost compression in the #8 cylinder. So here's my build so far: - De-lipped and reusing my stock LB7 pistons (if I don't need a bore)
- Carrillo connecting rods
- Socal camshaft and valve springs
- Balanced rotating assembly with Socal balancer
- ARP main and head studs
- LBZ injection pump in the valley twined with my factory LB7 pump
- Comp turbo CT6-94106 94mm 1.23a/r triple ceramic ball bearing turbo feeding a Comp turbo CT43-7279 72mm 1.15a/r, also ball bearing
- Exergy Injection 100% injectors
If the block does need to be bored then I will probably be going with Finger's cast oval chamber pistons and drop my compression down to maybe 15.5. I've personally done my own tuning on this truck but don't trust myself enough now when this much money and time is involved. So who is tuning it is still a toss up but not high priority now anyhow. My goal is to daily drive 700hp, be able to crank it up on the dyno, make some exhibition runs at the sled pulls, and still be able to haul my camper/goosneck with little to no smoke. Really have no goal for quarter mile times as this elevation sucks to race in period lol. Here it was installing the new injectors and the fresh powdercoating:   Then the teardown, again...  My S366 kit and water-meth kit removed (FOR SALE)  Parts, tools, and drinks piling up:    The turbos. Going to powdercoat them blue to match    |

I don't think he's gotten much done yet. I text him the other day about it in fact. He's been busy I think with SJ's

Work has been dead at the dealership lately so I've been real busy with side jobs to pick up the slack. Hoping to have the engine and heads shipped off to the machine shop here in the next few days and then possibly send out my injectors to Exergy and get them honed out finally. Last few steps before I can start re-assembling. Goal is May 17th!

So an update. Finally making progress as the dealership picked up and some huge side jobs paid off. A buddy has the heads and block at his machine shop. Turns out I slightly bent both intake valves on the #8 cylinder, which was causing my 200psi compression reading. Not sure how they got bent as the pistons showed no damage, but either way at least I have some explanation for my tear down. Ordering up valve springs this week, and sending my injectors off. Still on a toss up whether to do 60% or 100% over's. And I think I've decided against a camshaft right now as well. Need that money for other things.

For the size of your turbos, I would go 100 overs especially with the pro tuning you'll have and so many trucks now days successfully DDing big sticks. Everyone lately seems to lean towards bigger for the $. Then again, they may not last as long as I can attest to lol. |

I'll more than likely go with 100%. I know I'll regret it if I don't. Made more progress these past two days. Cylinder heads are done, just waiting for my Socal valve springs to show up. Engine block is done and sounds like it checked out great. Piston-to-cylinder wall clearance is around 6 thousands with my stock pistons so I think I'll be ok. Crank should be done today and Mountain High Performance has my pistons right now machining the combustion lip off of them. It's finally becoming a reality! If things keep up at this pace I should be able to start assembling next weekend! Sent a few things off to the powdercoaters today to get rid of the green:  |

Geeze I have been slacking on my own build thread! Have made some good progress since my last post. All my engine parts are back from the machine shop, started building my motor only to run into a fitment issue with my piston oiling rings. I'm running about 5 thousands clearance in the cylinders so my buddy that did all the machine work recommended to buy a 20 over ring kit and he would file them down to get the ring gap to exact specs. He completely spaced out that the oiling rings cannot be filed. So as of today I'm just waiting for another ring kit to show up. Once those get here it's game on! I just need one good weekend and it'll be back in the truck!
Well shit tried to post pictures but photobucket doesn't seem to want to work with me.
