Swapping Engine for you truck or jeep

Swaping engine for your 4*4 truck is not that easy as it sounds.

For some trucks or jeeps it is quite easy just like taking an enine out and putting a new one just like that without even changing the motor mount e.g army's most nimble jeep , but for some trucks or jeep it takes alot of welding, cutting, motor-mount changes and other things to modify because the engine doesnt not mount on the motor mounts.

Before you pull a stunt like this consider these few things.

1.Engine:

First of all make sure the type of engine you want is avialable and the cost of the engine not only to buy it but also to mantain it since there are few cars whose spare parts are hard to find e.g Nissan parts are easily avaliable in midle east but not in Asia. Check for such its motor-mounts, transmission, oil filter, air filter and for diesel engine always check for fuel filter and adpaters.

2. Cooling:

You must select an engine which usually does not heat up and the engine shoudnt be too big that there would be no space for radiator. Remember oen thing larger engines produce more heat so you would need a larger radaiotor>

Tip:

The front are of the radiator is more important than the core thickness. The larger the surface are more air it will draw thus making water more cool. A proper wide tube fan and aluminium radiator is a good option. Remember one thing a properly designed fan can reduce temperature excess of 20 degrees F.

Mechanical or Electrical Fan:

Electrical fans are more efficient but they draw alot of electricity from your battery resulting in decrease amps. For that your have to buy a bigger battery to your vehicle.

3. Emission.

Make sure it the engine is in good condition, because a smoky engine means the rings of the engine are worn out. do check that your seller has not decreased the flow of your fuel to engine just reduce smoke in order to fool you.

4. Skill Labour:

I think before swapping an engine the most important thing to check is that the do u know a good mechanic who can do the job.

5. Driveshaft, Transmission, Axles and T-Cases(only for 4x4):

Make sure the the engine you select is according to your drive shaft, many people swap big huge engines for power and in the end of the day they have a weak drive shaft and the bull, the inner rubber and other parts get weak because of over powered engine. If you want a bigger engine you may have to change the driveshaft which isn't easily available so get an engine according to the threshold of your shaft or get ready to repair it all the time.

Same goes for axles and transmission if you put an American V-8 beast in Japanese Toyota jeeps or trucks you will end up with slippery gears since your gear would loose their teeth. This happened with a fried of mine who installed 3800cc engine in his Nissan truck which was originally 2800cc. Always buy the right Transmission and whenever you buy an engine get the transmission of the same company. Specially if you are buying diesel engine for a car who had a petrol engine. Try to get the engine and transmission as a pair.

T-cases are usually tough since they are made of cast iron so u can take a risk on that, but if you are putting huge engine your need to upgrade your T-case since it could break the break or chain depending on the type of T-case.

Tip: When ever you select an engine keep in mind how much engine output you want, vehicle weight and tire size.
