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.

It´s better to buy a more powerful unit, than to modify the existing unit. As said before, a turbo will exert more stress on the engine parts, and that brings up some issues. The diesel engine, is build strong, so it is not that easy to break one by adding a turbo. But, you must know that, if you're mounting a turbo, you will have increased wear and tear on the engine, clutch and transmission.

Also, it would be advised to modify injection timing and so on, because, a turbocharged engine develops it's peak power and torque at a different rpm than a non-turbocharged engine.

It can be done, but the cost to do it properly, and to have substantial gain in HP and better fuel efficiency, it will cost quite a bit.

IMO, I think you're better off with the tractor as it is.

A Real Turbo diesel will have jets fitted to the bottom of the block to spray oil into special ports on the bottom of the pistons.To help with heat..as In Mercedes engine designs, I have noticed these in a few gas turbo engine. But if you have an engine in good condition and monitor like described above, you would have one to brag on.You should use a wastegate of some type to prevent overpressure..

Am i correct that Perkins names its engines after the cubic inch displacement ?? if so, the 268 would be 4.4 liter, which is enough to put out 80 to 85hp without a turbo. In fact Perkins sold these engines also in that configuration off the factory. Just turn the fuel pump up a bit, and forget about the turbo.

just turning up the fuel will also cause high EGT's. by adding the turbo you are increasing the air charge to burn the additional fuel. a turbo with mild boost will make more power and run cooler than just turning up the fuel.

 

[jonyyuma]

Some 4 cylinders jump up 40 hp with the turbo..higher with an aftercooler for the air breather.

 

[cowski]

a c70 is 60 pto horsepower and a cx105 is 85 pto horsepower.these tractors are basically the same except for the engines,even the injector pumps and radiators are the same.i can probably turn the pump up 15% without turning it into a fuel hog.i would like a little more power.any ideas?

I know that the guys who own non turbo Toyota diesel powered landcruisers are continually turbocharging the various models. They add turbos from new manufacture or they add ones they get from junkyard Chrysler models I can't name off the top of my head.

Here's a place in Australia that seems to have a going business in doing tractor and other concersions: Ray Hall Turbocharging - Custom diesel turbocharger installations

Usually the amount of boost is variable one way or another, and using low levels can increase power and fuel milage without doing damage to a non-turbo ready engine. If it's overdone a turbo can break most any engine.

Some engines will take a bolt on turbo just fine just have to do your homework on the engine in question and dont overdo it. We had a brand new ford 6610 in 1983 which went porous at 1900 hrs (2 years old) so when the new motor went in we ran it to 1000 hrs dropped a turbo on it and turned the pump up to dyno 92hp at the pto and sold it a few years ago with 7200hrs with no trouble .

Seemed a far more common thing to do in those days . Favourite models like Ford 7810/8210/7840...Fiat 100/90 and winner 100...JD3050..IH 956...There were probably more 7840 turbo's around at one point than natural ones .

The CX70 has the Perkins 1004.42 which is a low emission version of the 1004 series. There are Turbo 1004.42 and 1004.40T models referenced by Google in the European market. Just wanted to share that if it helps you find what you're looking for.

I'm considering adding a turbo to my 903.27 as they too were offered in that configuration from the factory. Mine is 48/45hp and the 903.27T as found on the CX60 is 64/56.5hp tested. That's not so much of a boost that I would get nervous about damaging anything. I want a turbo for the noise reduction, mainly.

Not quite sure mate.
