Does a Chevy supercharged 3.8 l fit in 3.8l montecarlo?

The short answer is yes, with some modifications. The 3.8L supercharger from the Grand Prix or Buick Regal will bolt right up to a 3.8L Monte Carlo engine, but you will need to make some modifications to the intake and fuel system. You will also need to upgrade the fuel pump, injectors, and spark plugs, and you will likely need to get a custom tune for your car.

It is also worth noting that while the supercharger will fit, it may not be the best option for your car. The 3.8L engine was not designed for a supercharger, and adding one can put a lot of stress on the engine. If you are looking for a way to add more power to your Monte Carlo, you may be better off looking for a different engine swap or a turbocharger.

Here are some of the specific modifications you will need to make to install the supercharger:

* Install the supercharger mounting brackets. The supercharger will need to be bolted to the engine block, and you will need to use the supplied mounting brackets to do this.

* Modify the intake manifold. You will need to modify the intake manifold to allow for the supercharger to be installed. This may involve cutting or welding the intake, and you may need to use a spacer or adapter plate.

* Install the charge pipes. You will need to install charge pipes to connect the supercharger to the throttle body. These pipes can be made from aluminum tubing, and you can use clamps or couplers to connect them.

* Install the fuel pump, injectors, and spark plugs. You will need to upgrade the fuel pump, injectors, and spark plugs to support the increased fuel and air flow that the supercharger will create.

* Get a custom tune for your car. The supercharger will require a custom tune in order to run properly. This tune will adjust the fuel and ignition timing to match the increased air flow.

Once you have made all of these modifications, you will be able to enjoy the increased power that the supercharger will provide.
