Over the years, customers have asked various questions pertaining to the durability of their vehicle, and whether or not additional modifications should be made in making them more durable. Below, we have listed some of the most commonly asked questions when performing a conversion, or preparing the vehicle for offroad use.



1. I placed my order yesterday, why has it not shipped yet?

Unless an expedited shipping method was chosen at time of check out, orders will take 24-48 Hours to be processed and shipped out. If the item in question is a custom build item (ex. Atlas, Saturn, Ranger) Additional time may be required.

2. Does Advance Adapters build custom (one off) Adapters?

Due to our rigorous schedule of production parts we are unable to make any custom (one off) adapters. Besides the time, it becomes exponentially expensive when taking in account all that is required producing components one at time.

3. Does Advance Adapters still make any conversion parts for Chevy Luv or Isuzu Troopers?

In short "NO"

4. Where can I get parts for my Hickey Sidewinder Winch?

The Hickey Sidewinder Winch has changed hands many times since Advance Adapters last sold it. As of right now we have no knowledge of its current owner or the supply of parts.

5. Will my stock axles hold up to the power and torque of the new engine?

For stock V6 engine conversions and most V8 conversions, the stock axles are acceptable. We have had several customers comment that, under normal use (with stock wheel and tire sizes), the stock differential assemblies work fine. The alternative to upgrading the rear differential and axle assemblies would be to install a custom made rear axle unit.

6. How strong is my stock transmission for use with the V6 & V8 engines?

Vehicles equipped with the early model 3 speed transmissions should seriously consider changing to a standard Ford or Chevy transmission. There are several adapters available and, in some cases, the cost is less than when using the original transmission. If the original transmission was the T18 or T176, it will perform excellent with the power of a new V8. The strength of your transmission should be regulated by your driving habits. If the original transmission is going to be retained, then we suggest you use caution when having the pedal to the metal.

7. How strong is the transfer case found in the Jeep vehicles?

The transfer case is sufficient to handle both V6 & V8 conversions. When the factory designs a transfer case, they have to allow for the added torque in the low range position. It is for this reason that they over design the transfer case gear box. We very seldom have a customer find the transfer case unsatisfactory in this regard.

8. Will I require a body lift?

Body lifts are very inexpensive and easy to install. They will provide additional clearance in the engine compartment area and also added clearance for the transmission tunnel area. However, most conversions can be completed without a body lift.

9. Will I need to modify my driveshafts?

It is almost impossible to answer this question due to the various engine and transmission options. Whenever possible, we will manufacture the components in a way that will prevent any modification to the driveshafts. You can usually plan on driveshaft modifications when installing V8 engines with a new automatic transmission. V8 engines retaining the stock 4 or 5 speed transmission will not normally require driveshaft modifications.

10. How long should my conversion take?

We have been surveying several of our customers over the last few years, and we have seen variations between 40 to 100 hours. The average time seems to range between 40 to 50 hours for the complete conversion.

11. I have a 1986 Camero TPI engine and I would like to install this into my Jeep vehicle. Is it possible to retain the fuel injected unit or would it be better to switch to carburetion?

It is possible to install the Tuned Port Injected 305 or 350 engine, but you must have a complete engine, including the wiring harness and the electronic control module. These will need to be installed into your vehicle along with all of the correct sending units and sensors. There are new wiring looms available to assist you in connecting the TPI engines into the Jeep vehicles. We installed a Chevy 4.3 TBI engine into a 1966 CJ5 using all of the original California smog equipment, along with a special wiring harness. We found the installation of the computer system to be excellent, and found very little difficulty performing the engine swap so that the vehicle could retain its smog legal status.

12. I live in California and if I do a V8 conversion, will it still be smog legal?

Our kits are not smog legal in the State of California. However, California law states that the engine you chose for your conversion must be the same year or newer than the year of the vehicle. Vehicles in the State of California that are 1972 and earlier are usually smog exempt. We recommend that you check your states laws on engine swaps before starting one. We do not provide a diagram or installation procedure for using the emission equipment. If you need assistance in this area, we recommend that you purchase the technical service manuals from General Motors,Ford or Chrysler, whichever pertain to your vehicle and the vehicle that the new engine came from. The manuals will give you the information that you will need to complete the installation of the equipment.

13. Will the stock radiator work with my new engine?

Depending on the size of engine that is going to be replaced will determine the feasibility of retaining the original stock radiator. If the original engine is a V6, V8 or straight 6, you should be able to retain the radiator size and simply change the inlet and outlet locations. If the previous engine was a 4 cylinder, then we highly recommend increasing the radiator capacity for use with the new V8 engine. Automatic transmission coolers can be incorporated into the stock radiator with very little difficulty.

14. Will the Jeep 4.0L engine interchange with the 258 6 cylinder?

With the introduction of the Jeep 4.0L in 1987, the engine block was slightly changed to incorporate two additional bellhousing-to-engine block mounting holes. The engine also requires a flywheel sensor that is not available on the earlier style AMC bellhousings. We manufacture a special conversion bellhousing (Part No. 712569) that will adapt the Jeep 4.0L engine Jeep vehicles 1976-86. There is also a bellhousing available for the 4.0L high output engine that will permit the use of the Chevy transmissions, such as the truck 4 speeds.
