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

What do you guys think about swapping the 3.6l lfx engine and 6 speed auto trans from a 2012 impala into a 2008 ls impala with a 3.5l

I know it wouldn't be a plug and play type thing bit they couldn't have changed that much to make it that much different.

Maybe that motor being the same as the one in the new
Camaro's and Cadillacs (but front wheel drive of course) will open up the bolt on performance aftermarket? Even slight modifications but still being able to make aftermarket parts work would be great!

Then having that 6 speed instead of the shitty 4 speed trans would be nice!

If the new impalas are geared different regear my car along with it?

I really have done 0 research on this and am just posting an idea that popped into my head 5 min ago.

Im just pickin brains and bein curious. I don't plan on doing this but maybe when my car starts getting up there in the miles it would be a strong option.

I think that with the cost, it would be wiser to just buy a 2012.

Well for one buying one brand new makes no sense the only way to buy is certified used after 2 years. That's when the cars aren't way over priced and rapidly decreasing in value.

Two I still owe $10,500 on my car loan and have a little over 4 years on my loan.

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.

If you can find a wrecked 2012 impala where the front end and engine are good, you might be able to make a deal. Make sure to get PCM with engine or just drop cradle on yours and swap in cradle of new one. That would be the easy way I would think.

Haha gasoline + spray bottle = squirt squirt under the dash. But then I would run into the whole expensive insurance issue and federal prison lol

The complete motors are $2000 I don't know about the trans. ECM and tcm are probaly a couple hundred. I doubt I'm gonna get a 2012 car or front clip for under $4000

It's about money and time. If you can afford to take your car off the road as long as you need to to upgrade and afford the upgrade, then it could be worth it. Honestly, the bigger problem is finding a rear-ended/totaled 2012 Impala.

Then I'm running into the whole Dollar per hp issue. I was planning out a remote mounted turbo set up that was only gonna run me $1200 in parts and I would do all the work myself and I stop planning it because I though there would be a better hp per dollar option being I could only push 4psi boost on stock internals.

Iv also been talking to alot of w-body performance companies about a adaptor to put the 3.8l intake manifold on a 3.5 then I could run a supercharger but it would need custom internals also to push any noticeable power.

Basically I was thinking in a year when my motor was shot this would bet golden ticket to some horsepower and a large aftermarket.

Your engine is gonna be shot in a year? Itll only been 5 years. That's a carburetor lifespan right there.

Now, if you wanna talk real possibilities...a RWD and LS9 conversion can be done with a little work, time and money.
