where can you find a add on turbocharger for a farm tractor?

Dealers parts dept for oem parts. Aftermarket turbos--don't know.

i have a cx 70 with a perkins 268 engine .the larger ones with turbo's are a perkins 244.my dealer is unsure if the parts off a 244 will fit the 268.i would hate to order them if they do not fit.

I believe M&W made turbo add on kits for John Deere 4020's around 35-40 years ago. As a turbo adds a lot of stress to an existing engine, make sure yours is in top shape. Besides mechanical stress, excess heat will also be another issue. You might need to turn the water pump faster, and or add a larger radiator.

...and change injectors and pump timing. Adding a hairdryer don't always add more power...without other modifications.

Aren't turbocharged engines ported differently for the increased airflow?

You can find everything you need on E-bay if you know what you want/need and at a very reasonable price! Adding a turbo does add stress & additional heat load but done properly and being reasonable with the power increase and operation you should have no reliability issues.
Diesels are very robust and typically overbuilt and can handle additional power easily.
New injectors are not necessary nor is it essential to adjust the timing; but timing will help in taking advantage of the additional fuel & air.
Most injection pumps have external adjustments for increasing the fuel (HP) and top engine speed.
Adding a turbo does not require head mods to accommodate the increased air flow.
Typically there are many differences in an engine that is turbocharged from the factory but that does not mean you cannot do it with good reliable results.
The important thing is to be reasonable in the hp increase and monitor engine coolant temperature and exhaust gas temperature..

No. The manifold is different and there may be internal strengthining ribs in the block or webbing in the head to absorb the increased pressure but no, the intake and exhaust ports are the same most of the time.

Most people don't comprehend what turbocharging or supercharging (in a gasoline engine) actually does.

It's like this....

In a naturally aspirated engine (diesel or gas), the piston, on it's down stroke (with the intake valve(s) open), draws in fresh air (in the case of a gasoline engine, air and fuel mixed). The intake valve(s) shut and the piston ascends, compressing the fresh air or fuel air mix in a gas engine. The main difference between the diesel and a gas engine is that the compression stroke, compresses the air to a point at which it becomes so hot that when the injector injects a mist of diesel fuel, it spontaneously ignites, driving the piston back down again and producing power. In a gas engine, the 'mixture' isn't compressed as much and a spark plug ignites the mixture, again driving the piston down and producine power.

The addition of a turbocharger or a supercharger (on a gasoline engine) does absolutely nothing other than pre compress the intake charge, effectively increasing it's volume and rasing the base compression ratio, which is why turbocharged/supercharged engines are usually strengthened internally, to take the added stress of the raised base compression ratio, increased by turbocharging/supercharging.

The reason your exhaust temperature is higher is because the charge is heated by compression of the turbine wheel in the turbocharger.supercharger so the inital charge is hotter before it gets compressed by the piston.

That;s why it's imperative to adjust not only the injector timing to compensate for the hotter intake charge but to assure that the engine can take the added stress.

That's also why it's advantageous to cool the charge air prior to it being introduced to the combustion chamber. That's what air to air or coolant to air coolers do on modern diesel engines.

in anutshell, that's what happens.

...Sort of like filling a ballon to full and then adding some more. If it isn't strong enough, it breaks........

BANG

If you want to get more power out of your engine, why not just do things like cleaning the injectors, porting the manifolds, bigger air filter, those sort of things, although the increase wont be as much as adding a turbo, it will be less likely to destroy the engine.
