Garrett Turbo

MJ Marks asked:




Turbo kits are turbochargers that can be purchased in kit form for installation in your vehicle. These are pretty cool! A turbocharger is a performance part that will boost the power of an engine by a whopping 40-45%. It’s true that some cars ship with a turbo already installed as part of the stock package, but most don’t. This means if you want to get the power and efficiency that one of these bad boys will give you, then you need to find a kit that you can install yourself. Of course, you could always buy one and have someone else put it in your car or truck for you. Regardless of who puts it in, it’s nice to know that you at least have the option.

Let’s talk about some of the different parts that you can expect most turbo kits to include, and some of the details about those parts. This is not an all-inclusive list and there are obvious differences between manufacturers.

First of all is the turbocharger itself. This is the central brain of the whole thing. It’s where the magic happens. Basically, these things work by compressing air from the gases that come out of the engine after the fuel and air combust. This air is then directed back into the engine, thus allowing more power to be created by the engine on subsequent combustion cycles. Obviously, different turbo kits are going to have different size chargers. This means, in broad terms anyway, that the larger the turbocharger, the more power is potentially generated. But don’t think that larger is always necessarily better. The large turbochargers do take more time to spool up and, therefore, take a bit longer to max out. This means that you shouldn’t expect full power to be had until after a bit of lag that is often experienced during throttle-up. Not a big thing for most, but certainly something to note.

Turbo kits almost always include an exhaust manifold. This is a part that directs expelled gas away from the engine after it combusts. Since exhaust has to be routed alternatively from the normal route (through the exhaust pipes), it has to go out an exhaust manifold designed with this purpose in mind. Turbochargers use the exhaust for power so this only makes sense. Right? Right.

Another thing that turbo kits often include is what’s referred to as a wastegate and blow-off valve, respectively. These serve to regulate pressure. The wastegate makes sure that the pressure in the exhaust manifold going up to the turbocharger isn’t too high, and the blow-off valve makes sure that the pressurized air that leaves the turbocharger isn’t too high when it goes back into the engine. Pretty straight forward stuff.

Turbochargers need an oil to keep things lubed up and moving properly. Excessive heat equals bad. So, turbo kits usually have an oil supply and appropriate return lines to help keep things cool.

Finally, better turbo kits will include an intercooler. Again, heat is the enemy. An intercooler works to keep the compressed (and heated) air as cool and dense as possible so that power can be maximized.

Turbo kits open up a whole new world for people interested in performance parts. They boost the power to your vehicle by compressing air. If a little attention is paid to what is included in aftermarket kits then a high degree of satisfaction can be expected. Vroom, vroom!

I actually have a 4.2 engine but Im putting a 4.0 HO head on it, the thing is, the 4.0 head has an exhaust header not a manifold, so would it be easier to find a regular manifold or is there a way to put a Garrett T3 on to the header?

Obtaining the most out of your engine has been the goal for many people over the years. There are several types of engines: normal aspirated engines and engines that make use of turbo and compressors to obtain more power from the same cylindrical capacity.

Modern car engines are more efficient and powerful than the engines produced twenty years ago, but there is still place for improvement. For example, if you have a normal aspirated car, you can add a turbo-compressor to increase the amount of horse power the engine develops. But before you rush out to the first car parts and buy a turbo charger for your car, there are things to consider.

The most important thing you must take into consideration when thinking of adding a turbo to your car is to think is the engine’s parts will be able to sustain the extra power from the turbo.

Adding a turbo requires quite a few engine modifications, and the outcome will be more power from your initial power, but will also bring higher temperatures inside the engine and the very high revs the turbine will function.

The German BMW’s are already known for their superior handling, reliability and power, but you squeeze a few more horsepower from your BMW engine by adding a turbo charger.

Compared to other methods of obtaining more power from your engine, superchargers offer less costly and an easier to install kit (these kits make 6-8 lbs of boost and the average home mechanic can safely install a quality application in 6 hours). Superchargers will typically make an impressive horse power increase, but many suppliers do not make a tremendous amount of low RPM torque, so if you only drive your car to work across the city, a turbo will not bring you significant advantages.



There are many components that a turbo charging set contains, as it is made up of thing like the intercooler, the bypass valve, the blow off valve, a waste gate, exhaust manifold, larger injectors and many more.

The typical home mechanic will probably be unable to complete this installation and that is why you should address a large car repair or tuning shop to complete the operation. Even for an experienced mechanic, mounting a turbo kit will take several days of work.

However, due to the significant increase in power a turbo kit brings your car, the wait is worth it. But when considering turboing your BMW, you should also consider improving your car’s brakes, as a 500 horse power BMW will require a lot of braking force to bring it to a stop from the astonishing speeds it can achieve. So the braking system should also be improves when mounting the kit (elements such as larger diameter rotors, multi piston calipers, sport brake pads, stainless steel brake lines and performance brake fluid should be on your shopping list).

You should also pay special attention to the BMW’s drive train when thinking of turboing your BMW. The initial car was developed to handle only a certain amount of power and any increase in this amount of power can affect your car’s stability and ability in taking corners if you not strengthen up essential parts in the BMW’s drive train (such as the clutch).

Also the car’s cooling system should be upgraded as well when turboing your BMW, as power generates heat and the initial radiator had been developed to eliminate just a certain amount of engine heat.

So you may think that adding a turbo kit to your BMW is an easy operations, but the truth is that if you want to have a professional operation done, there are other elements beside the engine itself that have to be modified.

The key reason why automobiles were even invented was to shorten traveling times, whether by sea, land (via railroads, coaches or by foot) and by air. The cultural impact is undeniable, as the world figuratively got smaller. It didn’t take long before the automobiles became a source of competition. As such, cars became faster, stronger, safer and came with all kinds of add-ons, effectively making it into its own unique lifestyle.

But that wasn’t enough. Consumers during the 1950s felt that the automobile could do so much more. Tuners or gear heads became a known collective that specialized the performance and appearance of cars. Street racing was gaining popularity and it wasn’t long before someone saw the business potential. Thus, the aftermarket business was born.

The aftermarket provided a service that allowed consumers a cheaper replacement for existing Oringial Equipment Manufacturer (OEM) parts, and add-ons to tweak the style and performance of their vehicles. At present the aftermarket is still widely popular, even extending services to younger car makers like Saturn Corporation and its trademark S-line series of cars.

The ultimate and arguably the most sought after custom part would be turbochargers or turbos. Of all the possible upgrades, turbos improves the size-to-output efficiency of the car’s engine. Usually consisting of linked turbine and compressor, both sharing the same axis, the turbo seeps in exhuast gases through the turbine coming from the exhaust manifold. This in turn, causes the wheel of the turbine to rotate, thus driving the compressor which compresses completely enveloping air that is pushes to the air intake of the engine.

Using a Saturn car as an example, the process works by having the Saturn turbo heighten the pressure of the the air that enters the engine’s cylinder. The low pressure created by downward stroke of a piston can only draw in a certain amount of air, thus the balance of molecules of air and fuel is not set to fully optimize the engine’s power. Saturn turbos in this effect, regulates the the increase of the intake pressure to “overclock” the engine.

Saturn turbos and that of other makes are easily available in shops that specialize in tuning and customization. However, some locations may not be blessed with an active tuning community or avenues which sell them. As such, aftermarket companies have started establishing an online distribution method that delivers the parts right at the buyer’s doorstep.
