Regarding the engine and 4WD
Talking about the engine, which is most prevalent in automotive gasoline and diesel motor fuel. The diesel engine has the advantage in terms of torque (torque) due to the compression is relatively higher. Moreover combustion systems that rely on pressure, making diesel engines more efficient than gasoline to be ignited by the spark plug. It is therefore not strange today diesel engines is far superior to gasoline, both in terms of power and torque. With technology common rail direct injection (CDI) based on the availability of near-constant pressure, a small diesel engine capable of matching the performance of a bigger petrol engine. At Toyota Land Cruiser (TLC) series 200, 4.5L V8 CDI diesel version twin-turbo power equivalent to a 5.7L V8 VVTi petrol version. While the torque CDI diesel 700nm, much higher than the VVTi petrol separohnya only.
Jeep too. The latest Jeep, Wrangler JK, and J8 gasoline and diesel. Benisn engine is Chrysler's Jeep JK 3.6L V6 Pentastar equivalent in performance to the diesel version, CDI 2.8L turbo. But the superior torque diesel. Therefore specific to the military, J8 models only the diesel version.
For rough terrain, more torque than horsepower required, given the many steep climbs and muddy ground subsidence that car may not be driven to achieve maximum horsepower. What is needed is a capable menggentak torque at low RPM. Therefore more suitable for diesel 4WD vehicles. Let alone these days which is no less horsepower diesel with gasoline. Down in the 1990s was where they were defeated horsepower diesel, 4WD diesel does not require too great. Are important enough torque. TLC should FJ4x gasoline with 2F engine capacity of 4.3L I-6. While the diesel version, BJ4x, enough engine 2.9L I-4 1B or 3B 3.4L I-4. In off-road terrain, the only 3B 100PS engine feels even more powerful than the 160PS 2F because torque 3B 2F nearly 2-fold.
Engine transplant experience for 4WD SUV
Well I happen to ever happen to another hobby 4WD and not much money. So would not want modified old 4WD. Understandably, the new 4WD is generally more expensive than regular cars. I was forced to buy a Jeep CJ-7 series (Laredo) and the 1983 Toyota Land Cruiser (TLC) series 56 (Commando) in 1980. Both diesel and the very old. Because his condition was very poor, so I replace both with a newer diesel. The transplant was officially declared in the reg.
TLC is relatively easy because almost every model and every series there is the diesel version. Even supposedly TLC default is diesel. 3B engine (100PS power and 240Nm of torque) I replace with 14B (115PS power and 270Nm of torque) and there's no problem because all compatible. The 14B engine is not used Toyota Dyna truck, but indeed for TLC equipped with vacuum compressor and power steer and air conditioning compressor fastener standards. So it is not complicated to make and install accessories that size must be precise. I did it in 1998 and till now running smoothly. For off-road and long-distance trip out of town is pretty good as padded. Strength quite okay for a car that old. To run on the highway because only 4-speed forward, certainly not comfortable above 110 km / h, although still capable of up to 130 km / hour. But for offroad, TLC transmission is very prepared for it. Much better than the Jeep. With tires 33 "just do not lose torque though still positioned 4H, 4L position is equal Jeep.
Jeep is fairly ridiculous. The 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 transfer-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.
