Hint #2: exhaust systems for the ’01-’04 LB7 will fit all ’01-’10 Duramax trucks, minus a few subtle tweaks.
#Alternate locations to mount a fass 150 duramax upgrade
Most LBZ owners opt to upgrade to a full 4-inch or 5-inch exhaust system at the same time the 3-inch downpipe goes in, which provides further EGT reduction. Hint #1: the downpipe fitment is the same on all ’04.5-’10 engines (LLY, LBZ and LMM, respectively).

And just like the LLY, a tuned LBZ’s exhaust gas temperature can drop as much as 150 degrees F by installing one. Utilizing the same turbo platform as the LLY (the aforementioned Garrett GT3788VA), the same 3-inch aftermarket downpipe is used. Larger Downpipe & Aftermarket Exhaust System This means elevated exhaust gas temperature (EGT) and a harsh working environment for the turbine side of the Garrett turbo. The oval-shaped, bottlenecked downpipe is fine for stock power levels, but it limits exhaust flow out of the turbo significantly once the engine is tuned. Not unlike the LLY, the LBZ Duramax left the factory with a highly restrictive downpipe hanging off the back of the Garrett GT3788VA variable geometry turbocharger (VGT). For a quality aftermarket Allison build, he turned to LinCo Diesel Performance, which offers a Stage 2 street and tow Allison for a budget-minded $3,699 and that’s rated for 650rwhp.

The truck, an ’06 Chevrolet Silverado 2500 HD, was making 460rwhp and 850 lb-ft of torque (and the driver was definitely enjoying himself), but the damage had already begun. The burnt C3’s pictured above came out of a stock six-speed, which had only been exposed to additional horsepower for 11,000 miles. So what does all of the above mean? You guessed it, you still have to pull the Allison, tear it down and rebuild it with better parts if you want to have your cake and eat it, too. Built Allison = The Only Way to Enjoy Added Horsepower While this is a step in the right direction, most aggressive tuning files add more than 200 hp to the equation. Whereas you can send roughly 90 hp over stock through the five-speed Allison, long-term, the six-speed version can handle 120 hp over the factory rating, long-term. Though the six-speed rendition of the Allison 1000 transmission (which debuted alongside the LBZ in 2006) is stronger than the five-speed used in conjunction with the LLY and LB7, it still has its limits in factory form. As you move into the 530rwhp range, you’ll discover that the LBZ’s performance potential is virtually identical to the LLY’s, which also means the stock turbo, injectors and CP3 will all have to be upgraded in order to take things to the next level.

Then it’s time to add a lift pump and ditch the restrictive factory Y-bridge-the difference here could be 20 to 40 hp, plus better drivability and reliability for that expensive injection system. After that, the familiar problem of addressing the squished turbo downpipe should be addressed with a larger diameter alternative. Like the LB7 and LLY that came before it, you have to prep the Alli to handle big power ECM calibrations.

The LBZ also benefits from added meat in the main bearing areas of the block, stronger rods and a more robust (six-speed) Allison transmission.īut even though the six-speed Allison is tougher than the five-speed unit it replaced, it’s still not strong enough to handle that 500rwhp tune in your arsenal. To this day, aftermarket CP3 pumps for Duramax applications are based on LBZ units. For instance, the LBZ Duramax offered in ’06 and ’07 employed a common-rail fuel injection system very similar to the one used on the LLY, but the LBZ debuted a higher pressure version (26,000 psi vs.

The slight differences from year to year (or RPO code to RPO code) stem from GM’s attempt to better its V8 diesel on the OEM level-with most changes making each new and improved Duramax even more potent than the one before it. While ’01-’10 Duramax engines share a lot of things in common and experience many of the same hurdles in making horsepower, these power plants are all a tad different in their own ways.
