What's up? I am very new here and thought I could come here and see about getting some info on my car if all possible. I have done a little research myself but failed! I have searched ZZ Performance, Hypertech, STS, and Diablo Sport just to name a few. I have an 06' Monte Carlo LT with the 3.9 litre. I am trying to see if there were any performance upgrades available for my car. As far as upgrades I mean cams, heads, supercharger, chips anything. Im looking to see if the 3900 and the 3800 Series 3 are compatible also. Maybe swap the intake and supercharger from the 3800 III or just say the hell with it and get an SS Help me please!? Thanx in advance!

 

The 3900 and 3800 are in no way the same- the 3900 is along the same lines of the 3500, 3400, 3100, etc- the 3800 is a completely different engine line.

Here is a place for mods:

bumpin, are you saying the 3.4 is somewhat the same as the 3100, 3500 and 3900? there is a girl I work with who has a 2000 3.4 and she wants to sell it! it has very low miles under 40,000 and I was kinda interested in it after a few pics/posts I've seen here recently or would I be better off with a 3.8?? just wondering, also, I have a 3.9 06 and there is not much for these cars? I think, any recommendations would be great, but I have a somewhat aftermarket warrranty that kinda limits my powertrain? but I do believe I can do a CAI and get a little more exhaust/muffler note without voiding my warranty!

 

The 3.4 in that 2000 monte is called a 3400- people usually reserve the "3.4" name for the 3.4 DOHC engine from 1995 and earlier. But yes, that 3400 is very very similar to the 3100- and overall fairly similar to your 3900.

I will say the aftermarket for the 3.8 - 3800 is insane. The 60* V6's (3100, 3400, etc) don't even come close in terms of what is available in the aftermarket for a 3800- and there have been so many 3800 builds done that you can pretty much pick a power level, and we can tell you exactly what mods you'll need and what it will cost.

If I was primarily concerned with cheap go fast goodies, and I had the choice between a 3400 monte and a 3800 monte- I'd definitely go with the 3800.

Other than the two sites I posted, I can't think of any other places (granted I'm a more 3800 biased guy). I know someone is supposed to be making headers here soon- but I'm not sure what else is available. Maybe one of the 60* V6 guys can help you more. I do know the 3900's haven't been out as long, so there likely aren't as many hardcore setups as there are with the 3100's, and 3400's that have been out for many years.

You've got to be careful with warranties and the powertrain warranty and mods. If they can prove that your mods caused the failure- they won't honor the warranty. For example, if you install an aftermarket FWI with the filter way down in the fender well- drive through a deep puddle and damage the engine from hydrolock- they won't fix it. Typically though, catback exhaust mods, and a CAI box are pretty safe. If you get too much more in depth than that (especially if you get to the point of a bigger cam, or some kind of boost)- then if something breaks in the powertrain, you're gonna be on shakey ground (ie break a trans hard part, or have a crankshaft failure, etc). However- they will still honor the warranty on everything else as long as it doesn't relate to the mods you've done.

 

The new 3500/3900 were basied of the same 60 degree V6 platform that the older 3100 and 3400 were based on. That said, many things changed about the engine when they came out with the new 3500/3900 V6's...Variable Valve Timing (VVT) being one of them.

Chris, I would stay away from the 3400, unless you want to sink about $1,200 into the car eventually to replace all the gaskets. (head, intakes).

In answer to the original question, not much is available for the 3500/3900 V6. The two sites bumpin posted are pretty close to it.

I would recommend the CAI from www.coldairinductions.com for the 3500/3900, and I would also recommend doing an exhaust set up.

 

i was going to say the say the same thing but you beat me mamonte ;P

 

Thanx for the help! I guess I will have to settle for the little ponies that I have or do a motor swap. The only thing I have done is put an K&N air filter in and bought two Cherry Bomb Turbo series mufflers. I havent welded them on yet though.

 

the 3.9 makes 240 hp has around 240 ft. lb torque...i think it is only 10 hp less than a supercharged 3.8...u have a decent motor IN MY OPINION.. i plan on buying a 3.9 soon to replace my older 3.4 in my 2002 LS MONTE CARLO

 

Actually the 3.8 S/C produces the same amount of horsepower, 240, but produces a lot more torque, 280 lbs stock. The 6th generation is also 250 lbs lighter than the 7th generation, and I believe the transmission gearing between the 3.8 S/C and 3.9 N/A are slightly different, not to mention there is a limitless amount of upgrades available for the 3800, so there's a big performance gap in them.

 

That's the big thing- even the 60* guys will admit to the fact that simple bolt on's are usually way more effective on boosted engines. 300 crank horsepower on an L67 is an afternoon and a few cheap, basic bolt on's away.
