Land Cruiser manual - Advance Adapters

Almost everyone would agree that
a Toyota Land Cruiser is a very
tough and durable vehicle - but it
won't last forever. When age,
abuse, or expensive replacement
parts reach their limits, and the
need for a new engine approaches,
that's where we can
assist you. Whatever your engine,
transmission or adapting requirements
may be, you can be assured
that Advance Adapters has
the answer for you. We offer a full
line of engine & transmission
conversion parts. We also manufacture
components for steering
upgrades, overdrives, and transmission
retrofits.
When deciding to do a conversion, the first step is to select
the type and size of engine you would require. You should
consider things such as dependability, power, economy,
speed, price range, adaptability, and availability of equipment
and parts. If you need the knowledge to perform the
ordinary to the extreme, this manual is your source for parts
and information. We have kits for new V6 & V8 engines, or
the original Toyota 6 cylinder engine. We have adapters for
use with the original 3 or 4 speed transmissions, or optional
truck-type manual or automatics. This manual deals
with several types of conversions, so you must be selective
in determining what information and parts will be applicable
for your specific conversion. Although the information
covers each phase of the installation, a separate instruction
sheet will come with your shipment illustrating how the
parts are to be assembled.
With reference to engine conversion kits, we have found
that the Chevy V8 is the most popular. We offer a complete
line of products for both the Chevy V6/V8 and Ford V8 conversions.
Depending on the year of the vehicle and the
equipment that is being used, you may or may not require
driveline modifications.
In recent years, one of the more popular conversions for the
Land Cruisers has been the use of the Ranger Torque Splitter.
The Ranger is a fully synchronized gear splitter that is used
between the bellhousing and transmission assembly.
When using the Ranger Torque Splitter, you will be able to
avoid the cost of special bellhousing adapters and the expense
of driveline modifications. Most Land Cruisers are
equipped with 4:11 axle ratios which are not the most comfortable
highway gears. When equipped with the Ranger
27% overdrive, the ratio is then reduced to a rear axle ratio
equivalent of 3.03. We offer the two speed in a multitude of
combinations. The gear box can be purchased to fit a Chevy
or Ford bellhousing on the front side, and either the Toyota
3 or 4 speed transmission on the back side. We do not
offer the Ranger to fit with the stock 6 cylinder because of
the overall length. This added length causes problems
with the fuel tank and transfer case linkage location.
INTRODUCTION
We also offer several optional
transmission-to-transfer case
adapter kits. If you find your original
3 or 4 speed transmission to
be in marginal condition, you can
select from the various GM and
Ford transmissions that can be
adapted to your original Land
Cruiser transfer case. Ford and
Chevy transmissions can offer
you several advantages such as
added strength, the elimination of
bellhousing adapter plates, and
the need for stock transmission
repairs.
In 1995, we began developing
adapters to retrofit the NV4500
transmission into the Land Cruisers. This transmission
has proven to be a very popular application. The overall
length of this 5 speed makes it ideal for V8 conversions,
since it positions the engine further forward for valve cover
and distributor cap clearance. We have also performed
this same conversion using the stock Toyota 6 cylinder engine.
This transmission offers a super low first gear ratio of
5.61, and an overdrive ratio of 27%.
Even though most of our Land Cruiser product line is designed
around V6 & V8s, our adapters will also work on the
GM 6 cylinders. The original Toyota 6 cylinder was very
similar in design to this GM engine. For those wishing to
retain a domestic 6 cylinder engine, they can easily install
this GM engine. The same adapters required for a V8 installation
would be used on this 6 cylinder, except for the
engine mounts which will need to be fabricated. Another
consideration for the GM 6 cylinder is the starter location.
When using one of our conversion bellhousings, you must
make sure that the starter bolts to the engine and not the
bellhousing since our bellhousings do not have starter
mounting provisions. When using a GM 6 cylinder with a
stock Land Cruiser 3 speed transmission, a body lift must
be installed for bellhousing clearance.
Mark's 4WD Adaptors: In 1993, we were assigned to
be the exclusive U.S. distributor for Mark's 4WD Adaptors of
Victoria, Australia. This company manufactures a Toyota
Land Cruiser product line very similar to the Advance Adapter
product line. The Land Cruisers in Australia have some
variations from the models that we have. The most notable
difference is the steering gear box, which is located on the
opposite side (our passenger side). Because of variations
such as this, we stock their products on a limited basis;
however, any of their product line can be special ordered.
Currently, the most popular items that we are importing are
their bellhousing adapters for all model Land Cruisers.
Their special bellhousing assembly, specifically for Ford
and Chevy V8 Land Cruiser conversions, bolts directly onto
the front of the original Land Cruiser bellhousing assem-
