For example, we have a 2008 Hyundai Accent. In Turkey, it is called "Accent Era".
Is it possible to install twin borgwarner turbochargers from two trucks and a supercharger from a Shelby GT500?
The 1.4 engine produces 96 horsepower. With the installation of the truck turbochargers and Shelby GT500 superchargers, can they increase engine horsepower and affect engine performance?
I suspect a 96bhp 1.4 engine would struggle to provide enough power to spin up a supercharger and two turbochargers. I also suspect that the charging units you have chosen would not be well matched to your engine.
Might I suggest obtaining something like an IHI from a Lancia Y10 Turbo, a G40 G-ladder from a VW Polo 1.3 G40 or a Garret from an MG Metro Turbo. Any of these units would be far better suited to your engine.
Installing a turbocharger or supercharger involves reducing the engines compression ratio. This can be achieved in a number of ways but probably the easiest is to get a lazer cut metal sandwitch plate and install it either side of two head gaskets. Alongside doing this you'll need to fabricate a custom bracket and pulley if you're going to supercharger route or custom exhaust manifold if going the turbo route. Whichever route you go, you'll need to add some induction pipework to deliver the boosted air to the inlet manifold. You'll need to have the ECU ignition and injection MAP reprogrammed to suit, this is best done on a rolling road. You may also need an oil feed to the charging unit as many of them require lubrication.
If it is your intention to install both a supercharger and a turbocharger you'd encounter significant engineering challenges as you'd be effectively "twin charging" the car. This requires some serious hardware. I am only aware of three cars that use a supercharger and turbocharger, the Nissan Micra ice racer, the Lancia Delta S4 Group B rally car and the Mk5 Volkswagen Golf GT 1.4 TSI. The Golf is probably the closest vehicle to yours, being a road car with the same engine displacement. This car makes around 140bhp so it does represent a good gain (around 40%) in power.
I would suggest that, unless you have access to a good engineering facility, this is probably not the most cost effective idea.
A few thoughts on why this is not as great an idea as it sounds:
the increased risk of detonation needs to be addressed if the engine is to survive for a meaningful amount of time. This could be achieved by reducing compression ratio (which requires engine modification), richening up the air-fuel mixture (which is bad for emissions) or intake charge cooling (which adds more complexity)
even if detonation is addressed there is only so much boost that a stock bottom end can take (pistons, connecting rods, rod bearings). To bolt on a twin-turbo'd + supercharged would mean that the bottom end needs reengineering if the full potential of such a setup is to be utilized
There is no such thing as free energy. And there is a point of diminishing returns. Running a supercharger off the crank will incur a certain loss of power. More boost = more parasitic losses, and it isn't linear. Turbos don't suffer from this issue as much, but physics is physics. Don't expect miraculous power gains just because the engine bay houses a turbo or two
Most of the fuel management system will need to be retuned or replaced. This will include the engine tune, air flow sensor(s), fuel pump and fuel injectors
Space constraints will limit what you can fit in the engine bay. If it doesn't fit, you'll have to figure out a way to make it fit because mechanical power doesn't get transmitted over wifi.
Lots of custom fabrication will be necessary to mount the additional hardware. This usually involves welding, making custom brackets, relocating stuff to keep things within the confines of the engine bay
Lots of money will be required to finance the above. Bucket loads of money.
Turbo or supercharging this car is a waste of time and money. The transmission(s) used with this car will likely not handle much more power than it already puts out.
