Does the LLY and LBZ have the same turbo?
Yes, the LBZ does make more power with the same tune level than a LLY…… unless you get a better breathing LBZ intake neck installed on a “true” LLY then they’re pretty much identical.
Are Duramax turbos interchangeable?
lly, lbz, and lmm turbos are all interchangeable. Just use the vane position sensor that goes with the model of truck so the plugs match.
What size turbo is in a 2005 Duramax?
One benefit for horsepower junkies is that the LLY made use of the largest turbo ever offered on any Duramax engine. Not only was its 62mm, 11-blade compressor wheel inducer the biggest, but the height of its exhaust vanes were the tallest at 15mm (vs. 11.2mm on the LML engine available from ’11-’16).
What is the difference between LLY and LBZ Duramax?
The ’06 LLY is much quieter than the ’05. The ’06 LLY and LBZ have the same turbo (ask McRat, he put one on his ’05 LLY). It has the reduced compression, meaning that it has the LBZ pistons. If the LBZ piston has an increased wristpin diameter, then it stands to reason that the ’06 LLY also has the LBZ rods.
Does LLY have variable vane turbo?
The 2004.5-2005 LLY was the first model Duramax to be equipped with a Variable Vane Turbo (VVT). VVT technology provides quicker spool-up, better EGT control, and better overall boost control. This is also commonly referred to as a VGT or Variable Geometry Turbo.
Is the lly a good motor?
The LLY has the largest turbo in it out of any other 6.6L Duramax variants. Outside of it being the largest turbo, it had the largest compressor wheel and the tallest exhaust vanes. The end result is having an extremely efficient and high-flowing turbocharger.
What size turbo does a 6.6 Duramax have?
The LLY (internally called the 8GF1) (engine code “2”) is a 6.6 L; 403.9 cu in (6,619 cc) turbocharged engine which debuted in mid-2004 and continued until the end of 2005. It is a 32-valve design with high-pressure common-rail direct injection and aluminum cylinder heads.
Is the Duramax LLY a good motor?
The 2nd generation Duramax is known as the LLY. Similar to the LB7, the LLY Duramax is reliable, powerful, and lacks most of the emissions found on modern day diesel trucks like the L5P. LLY Duramax trucks don’t suffer from the same injector failure problems that LB7 trucks frequently had.
Why is LBZ better than lly?
Torque increased as well, going from 605 pound-feet with the LLY to 650 with the LBZ. The LBZ employed a thicker engine block casting, meatier connecting rods, and a higher pressure common-rail fuel system. This gave it more power and reliability versus any other Duramax to that point.
