Jeep CJ7 Engine Transplant


Jeep's original engine is Isuzu C240 ​​diesel version. Actually this engine 80PS, Taft did not lose power with 70PS only. If installed on the Isuzu Trooper or Luv, stern-powered cash. Apparently the ratio of transmission and / or cardan Jeep CJ-7 was not prepared for a little power. Because if we feel, teeth-1 Jeep CJ-7 is almost equivalent to the 2nd gear another car, not even a 4WD. So with the 80PS engine feels very sluggish. This is definitely one of the design. Perhaps the use of Isuzu C240 ​​engine just here alone, without adjusting the transmission ratio and / or cardan usually to 190PS 4200CC petrol version.


In fact if we look at the old TLC, both series 4X, 5X, 6X or 7X series, between the gasoline (FJ) and diesel (BJ or HJ), in addition to different transmission, cardannya ratio was different. Because diesel in the generation of power is very less compared to petrol. Furthermore mounted diesel engine is always smaller, because the vibration of the diesel engine requires a much more robust structure that would impact on the price of the vehicle. So the factory decided to focus only on the torque, which exceeds the 2500cc diesel engine 4000cc petrol engine.

Back about the Isuzu C240 ​​engine, if we look at, is generally used to forklist or other heavy equipment insanely reduction ratio. So it seems the application C240 ​​Isuzu Jeep CJ-7 on here seem to be forced to publish a diesel version without proper engineering process. Perhaps in other countries Jeep CJ-7 diesel version using the above 100PS engine, office anyway so ready even for gasoline engines 6 cylinder I-6, which is quite long. Or it could be the transmission ratio significantly increased to compensate workers who just 80PS.

In addition, engine spare parts C240 ​​is very rare. When it should replace the piston rings, but half dead nyarinya. Finally I decided to replace the engine alone. I did transplant in 1994, earlier than TLC.

Looking for a suitable engine for the Jeep CJ-7 was not easy. Because as far as I know there is no machine that is compatible with the Jeep transmission. Looking at the weight ratio of the car and cardan, the most suitable and easy as possible with the engine Daihatsu Taft GT 4x4. But it should be equally trasnmisi and  ransfer-case and cardan her. Taft GT engine and transmission cardan against Jeep CJ-7 chances even more lackluster than the original. But it was again stuck about money. Of various machines that I have observed, finally falling on TLC 13B 3400CC engine options. The direct injection engine powered 105PS and 240Nm of torque, more powerful and more fierce than the original engine and machine Taft GT.

Transmission, transfer-case and cardan still wear the original. So it is urgent to make an adapter to bring TLC 13B engine and transmini Jeep CJ-7. Although difficult, and eventually the marriage berhasillah presents a Jeep CJ-7, 3.4L diesel is quite fierce and wild terrain is more powerful than the original version, either diesel (C240 2.4L, 80PS, 200Nm) and petrol (AMC 4.2L, 190PS , 160Nm).

Furthermore I am more pleased with the Jeep. The engine my own tooling utik including its fuel my heat just before entering the nozzle as I explained in a previous post. Waww .. increasingly fierce him. I pertebal 10mm chassis cradle and place the transmission in order to strengthen my mighty for jumping. Which had been planned but not yet accomplished is to replace the rear axle with full-floating. 1975-1986 Jeep generation construction weakness is the rear axle. Rotor removable from the axle, so often when forced dol in the toughest terrain.
