3.6l Lfx swap into 2008 impala ls with a 3.5. - Page 3

**kingnutin** · 07-19-2012, 05:08 PM

I have 2 3.5 motors well over 180k, and 4 others damn close to it, believe me, whatever you do to your engine is probably no worse than security officers do on patrol every night, not to mention the amount of time spent idling would realistically put that figure much higher. All I'm saying is, the motor isn't going to wear out, they just keep going. Its the rest of the car that breaks.

Looking forward to this TT V6 though, its about time GM joined the rest of the world!

Ejbiers · 07-19-2012, 05:37 PM

I'm already seeing all different kinds of oil seapage around and on the bottom of my motor. I mean most are probaly a simple bad gasket letting oils seap but it's only at 80,120miles. It's not a high compression high performance bored out stroked out motor. I shouldn't be seeing that. That just goes to show the quality parts put into this motor. Not to mention my water pump (I think) whining like a supercharger. This 3.5l motor is a joke an everyone thrashes them. They are a cheap throw away engine for a cheap throw away base model economy car.

outonthetiles · 07-22-2012, 12:52 PM

I'm all for this swap!

He didn't ask if he should do it, he just asked if it can be done. I don't see why it couldn't be done.

It would be the easiest to find a donor vehicle, as you'll most likely need the wiring harness, axles, motor mounts, ecm, tcm, downpipe, and possibly even the subframe in addition to the engine/trans.

I would imagine it's not that hard of a swap. Since it is a factory option in these cars, no custom adaptors or brackets would need to be fabricated.

Ejbiers · 07-22-2012, 03:00 PM

Yeah, i gave up on this thread awhile ago. It turned into flying vacuums and telling me how long my engine was going to last (as if someone who has no idea how i maintain it and how i treat it knows better than me). Advice is appreciated but not when its not requested and had nothing to do with the subject on hand.

For those of you who do care about the thread subject...

This looks to be a smart swap as of now and with time this will only prove itself. This motor being so new everything is very hush about it. But this motor will be taking on a huge role.

GM is looking to make this motor the new golden child V6 and is heavy into development with it. They are trying to duplicate what they had with the 3.4l and 3.8l. They are trying to accomplish this with the 3.0l taking the 3.4's place and the 3.6l taking the 3.8l place. This could also be said with the 3.5l/3.9l but they weren't as popular as the 3.4/3.8 and are being phased out after just 5 years.

This LFX 3.6l motor is said to be able to push 350hp with just a premium fuel tune all motor. That is without the twin turbo setup that is said to be in the works over at gm as a factory option reported in the 425hp range. You could also get a bolt on supercharger setup that includes everything down to the ecu and push 440hp on premium fuel and same mpg for $5700.

I also love the idea of a integrated exhaust manifold. Very nice for the absolute ease of turbocharging and motor swapping. Lower emissions, narrower engine size and noise reduction. With the catalytic converter closer to the engine exhaust point, the emissions reduction process begins sooner, resulting in lower emissions. The new cylinder heads decrease the overall width of the engine by 4.6 inches (117 mm) for significantly more packaging space in the engine bay making underhood work easier. Due to less surface area, the new design contributes to a 1 decibel reduction in engine noise at idle.(some of that from a article found on the internet60DegreeV6.com - 3.6L DI Heads w/Integrated Exhaust Manifolds)

The new composite intake manifold from the factory also gets me excited. Composite intakes can be a lot stronger and resist heat a lot better than any metal. That is perfect for making the most of your forced induction, keeping the intake air cooler and keeping your intake intact under positive pressure.
Just take a look at the composite lax intake for the ls1/ls6 that fast just came out with. Even has a way to vent intake pressure should a backfire happen or you push too much boost.

outonthetiles · 07-22-2012, 03:12 PM

Yeah, the 3.6 is a very interesting engine. Have you done any research on actually swapping it yet?

Ejbiers · 07-22-2012, 05:30 PM

I have done a lot more research on the motor than the actually swap since is the motor is crap then the swap is a no go but...

I havent gotten a chance to look around a 2012 in person yet but i do know nothing has changed on the body or structure of the car. Maybe couple small things beefed up but that isn't a big deal in the big picture. The 2012 even has two holes for the engine torque strut mounts for the 3.5l/3.9l even though the new 3.6l only uses the left one.

The exhaust has a tight horseshoe in it but i would probably be getting rid of that anyway in favor of a less restrictive down pipe setup.

The throttle body is angled a little bit it doesn't come straight out and its further back toward the firewall but not a big deal.

All in all if you get
complete motor
trans
all the mounts
computer
maybe a couple of wiring harnesses for misc parts that have different connections on this motor (MAF,Electronic throttle body, ect.
Maybe 2012 transaxel
With that you have a great start. Motor swaps aren't for the weekend warriors anyway so for most of us that seems to be pretty solid. I am pretty sure they rushed this 3.6l into production in the impala and didn't change too much to do it. They didn't have time to redesign anything to the point it would be possible with minor modification but i believe its gonna be bolt up. Bolt on 3.6 mounts in the same place the 3.5 mounts went, they are just going to be different mounts MAYBE.

Some wiring might have changed. If it did its gonna be as simple as splicing on the right connectors or lengthening some wires. Maybe even buying a whole new wiring harness to take a easier route. Maybe you could have someone program a 3.5l ecm to the 3.6l data if all the connectors and wires are different. I doubt it being the 3.6 is a DOHC but you get my flow there are a ton of options.

Like i said before i think in the long run, this would be worth it. When the N/A V6 to N/A V6 swap gives you the possibility of 440HP of bolt on performance on stock internals with a automatic six speed and 30mpg. Maybe even do some HiPer Strut changes on it from the Buick LaCrosse to handle all that HP.

Oh man it gets me excited thinking about the old impala putting up numbers like that.

outonthetiles · 07-22-2012, 05:51 PM

Yeah, I would assume that you will need the entire harness, I would bet that it has different sensors, and in different places.

And definetly go with the 6 speed if you do this swap.

Keep us updated if you continue with your research..

Ejbiers · 07-22-2012, 07:16 PM

To respond to some talking about a ls4 swap. I'm on multiple threads tearing apart that motor and set up so I'll just keep it short and sweet.

It would cost just as much money to swap a ls4 in here as it would the 3.6l. That is why everyone comes on here and says a swap isn't worth it an it will Never happen. They aren't used to a real solution to the underpowered 8th gen impalas.

That being said why would anyone swap in a heavy underpowered joke of a v8 into a fwd car. There is barely a aftermarket for the ls4 anyway and the little bit that is there is expensive parts for little horse power. As one member said to me, this guy has a full bolt on car and he is making a little over 400hp. Well that's great for him but I know you aren't getting the same MPG, I'm sure your torque steer with that huge v8 tightly squeezed in there is nasty and I'm sure your trans rebuild when it broke when it was stock was expensive and I'm sure it was even more expensive when you decided to beef it up for that much hp ( a whopping little over 400hp that is)

Oh an I'm sure your thrilled about all that time and money spent on a 4 speed automatic and 400hp.

I will deffinitly keep up with the research and keep updating this thread. Hopefully it will be informative for me down the road and also anyone else thinking about a 8th gen with some power. If I did decide to take any real world action on this I wouldn't be doing it for another year at least. Even if my motor does go I would be forced to repair and rebuild since money is gonna be tight for awhile. (life just isn't fair sometimes).

But if anyone does want to go through with this I'd be more than happy to help with whatever I can. Even the swap itself if your in the pa/Nj area. I'd love to make a real impala out of these 8th gens. It wouldn't be a RWD ls6 but it would be the best reality thing we can do.

MrBR · 07-22-2012, 08:55 PM

If the 6 cylinder had more of V8 roar and I wasn't ashamed of having a V6 I'd consider putting it in my 1964 Impala, I'd probably love the gas mileage

**donmateo** · 07-22-2012, 09:31 PM

Put a 6.2L truck V8 in. Those sounds sick

MixedImpala04 · 07-23-2012, 01:12 AM

Just go get a GTO or a camaro and be happy. Or a G8. And there is a ton on aftermarket for the LS4. Your not looking in the right place.

csawyer · 07-23-2012, 05:37 AM

I think it's a really cool idea, but I just don't see it being done for the $5700 you quoted. Being the cynic I am, there's just got to be something about it that would make it more difficult than you'd think and cost a couple G's more than that. My bigger question is what is it about the 8th gen body that you like so much that you'd go to all this trouble for a daily driver? I like the look of my car, but there are only a million of them on the road. If you had money to burn and wanted to make a one-off that would only be driven for fun, I'd say by all means, go for it. The possibilities are awesome and I would say it could definitely be done, it just seems like a lot to go through for someone who actually drives his car the way you do. Using your own logic against you, you'll go through all that for a motor that will be much better, but you'll still wear it out in 5-6 years? Since you're looking for a swap with some power and longevity potential, why not go for a diesel? I'm just saying...

Three I'm 19 and no way I will get financed on a car that new without 50% down even with my connections. ( my score is great but history is only a year old

Four insurance for a brand new
Or even 2 years old on a upgraded and faster car will be through the roof.

Five I have alot invested in after market parts and don't have my stock ones to swap back on. Body, interior, electrical, ect. No room and too much money just sittin around.

Six I have done alot of jap and german motor swaps some very rigged and some very nice and they are never way to difficult or way over costly ($3000 max).

Basically the answer isn't always buy a new car. While it is alot easier to swap cars. It's just making the best of what you have. The rest of my car is pretty good for having 80,000miles on it and it doesn't make sense to get another car just for a motor. Esspecially when you owe more than its worth.

Thats why I don't buy a g8 or a srt8 charger or 300. I also don't want a two door. And insurance is sky high on those cars for a 19year old. Another car isn't an option it's about making the best of what I have period.

Say this new motor does go in 4 years. I would have no problem ripping it apart and rebuilding it on a weekend for a grand or so. This motor would be worth it and I wouldn't wanna kick myself for dumping money into a piece of shit 3.5l that is already being discontinued or rebuildiń this garbage 4 speed slush boxes in these cars. It would be worth it to put the time and money into it when I have a 30mpg supercharged v6 with 440hp or even a twin turbo setup. That would be a setup worth fixing and rebuilding and keeping for many years to come.

Honestly when my loan is up I'll be going and getting a Chrysler 300 srt8 or a g8 gxp. I'm a four door guy. I have always had coupes (toyota supra, grand national, camaro, monte Carlo, Lincoln mark viii) and I just like a 4 door car that is fast. Why the hell is that such a issue with Chevy. I really hope by the time I'm in the market for a new car that they have a rwd or AWD 4 door with either a v8 or a boosted v6 making at least 415hp. If they do I might be a Chevy customer again.

Buy one of those new caprice police cars later and put impala badges on it.

Ejbiers · 07-23-2012, 12:09 PM

And there is not a ton of aftermarket for the ls4. There are some stupid parts and swaps you can do for little hp gains and big money. Then you still have a 4 speed trans that you paid $3000 to be built up to handle 400hp.

Im done talking about that motor. This is a 3.6 lfx swap thread not a what motor should I swap thread. The ls4 has nothing to do with the original thread.
