Bad Azz LZ9 -3.9 Engine: )
[/align][/align][align=center]GM High Value Engine [/align][align=center]Member Cain45, per your request : )
[:-]
Manufacturer:
General Motors
Production:
2006–3LT & LTZ
Predecessor:
GM 60-Degree V6 engine
Class:
60° OHV V6

Engine:
3.5L (3498cc)
3.5L (3510cc)
3.9L (3880cc)

The High Value engine family from General Motors is a group of Cam in Block or "Pushrod" V6 engines. They use the same 60° vee bank as the 60° V6 family they are based on, but the new 99mm bore required expanding the bore spacing by 1.5mm. These engines are the first cam in block engines to implement Variable Valve Timing, and won the 2006 Breakthrough Award from Popular Mechanics for this innovation.

242 @ 6000 rpm (Impala & 2006Monte Carlo only)

Torque:
235 lb-ft @ 3000 (G6 Convertible)
240 lb-ft @ 4600 (G6, Malibu SS)
240 lb-ft @ 4800 (SV6, Uplander, Relay, Terraza)
242 lb-ft @ 4800 (Impala, Monte Carlo)

Features: Dual Variable Valve Timing
Roller Rocker Arms
E85 Ethanol Capable (LGD only)
It produces 242 hp at 6000 rpm with torque tuned to 242 lb-ft at 4400 rpm. The new LZ9 3900 features Variable Valve Timing, a new feature on a pushrod engine, roller rocker arms and has a variable length intake manifold. It is expected to produce 242hp (179kW) and 241ft·lb (332Nm) torque, with a wide torque curve.

I wonder when, and if, there will ever be 'mods' for this engine?

 

 

Space,

Thanks for taking time out to find all this information.

My '06 3.9 LTZ thanks you as do I. [sm=exactly.gif]

 

Thanks for the info. I thought about trading it a while back then reconsidered. I've put a lot of money in accessories on it and they are rare. So I decided to keep it probably for at least 3-4 years maybe longer. I really enjoy driving it. Tried to wash it tonight but with windchills under 0 it just froze onto the car. I got to wash the salt off though. I can't wait for spring when I can get out and detail it again.

 

from the looks of it he 3.9 is going to take the place of GM's 3800 as the standard do-it-all engine for the new cars! that means plenty of companies will be making parts with such a hughe crowd out there. if DHP the company who makes my programer, gets support for that engine, it will be a real powerhouse!

-Headers
-Full exhaust
-FWI
-180 Tstat, colder plugs, adjusted spark timing
-Ported TB and Intake manifold
and it will be crazy! esp in a 2door G6!

unless GM desides to strap a blower to it, it will take some good tuning to get a SC working on that car...same goes with a turbo. you have to get past the VVT. but if you can tune the VVT thru the computer....then yeah it will make crazy power!

but for now he L67 (3800 SC) is the king of the FWD GM cars

 

King yes, but VERY dated engine too.

 

 

Oh yea they last that's for sure....considering they've been around for over 30 years now!

[/align][align=center][/align][align=center][/align][align=center]GM 3.9-Liter V6
General Motors keeps finding ways to advance pushrod camshaft engines. The company's latest move is to adapt variable valve timing--common in overhead camshaft designs to maximize performance at both lower and higher speeds--to an engine with a single camshaft mounted in the block. GM's 242-hp 3.9-liter V6, introduced in the 2006 ChevroletMonte Carlo, is the first such two-valve system. It soon will have Displacement on Demand, improving fuel efficiency by disabling half the cylinders when they're not needed. gm.com WoW, a 3 cylinder : ) Go slow, save fuel, don't have any fun...Vroom ===== [/align]
