6 ENGINE CONVERSION CONSIDERATIONS
ENGINE CONVERSION
General Information
Once the selection of your engine has been made, there are now a number of items that you must consider. The information listed
in this section will cover most of your conversion considerations.
MOTOR MOUNTS:
Your next requirement will be to purchase the proper engine mounts. The motor
mounts we offer are for the Chevy V6/V8 and Ford V8. The V6/V8 mounts are a
complete frame-to-block mounting system that uses a dual rubber donut design
fastened together with a hardened bolt. This combination offers a positive
means of securing the engine for the most severe offroad conditions.
Our universal motor mounts can be adjusted to accommodate the
best possible engine location. Our universal Chevy and Ford side
mounts are your best choice for Land Cruisers. The universal mounts
are designed to be welded into position. When you position your engine (with the weld-in
mounts), you must take into consideration such things as oil pan, steering box, and firewall
clearances. Our Chevy V6/V8 mounts include new scab plates that should be welded to the
inner frame rails. This will allow a better weld for the engine support bracket to the frame.
On Ford V8 universal mounts and LS1 mounts, the frame enclosures can be ordered under
P/N 713124-PLT.
Our engine mounts are provided with multiple hole locations for assembly between the block mount and
frame support bracket. The holes on the engine mount will not always line up perfectly over the "L"
support bracket. When your engine is lined up in the desired location, it may be necessary to elongate
one of the holes on the engine mount.

ENGINE LOCATION:
Depending on your engine selection and transmission type, you will find that the Toyota Land Cruiser chassis has ample room.
We have established some guidelines for the most popular conversions, but due to the various combinations we suggest that you
consider all of the options before final drivetrain location is established. Keep in mind that the original driveshaft length can be
maintained - provided the transfer case is kept in the original location. Many times customers will sacrifice engine location to eliminate
driveshaft modifications. We highly recommend that you position the engine in a location similar to the measurements to follow.
Driveline modifications are cheaper in the long run than improper engine placement.
The correct engine location on a FJ40 is easily determined by measuring from the rear edge of the shock tower. The placement
of the “L” bracket will vary because there are several drivetrain combinations. An ideal location for the “L” bracket is between 8” to
12” from the rear of the stock tower to the center of the “L” bracket. When placing the engine between the frame rails, it should be
offset 1/2” to 1” (depending on which transmission is being used) toward the driver’s side to allow for proper front driveshaft clearance.
When positioning the engine, the height of the “L” bracket should be either flush and/or up to 1/2” above the frame rail. This varies
due to the lateral location of the “L” brackets. Ideally, the engine should have a 3 to 5 degree tilt towards the rear once the engine
and transmission are installed. NOTE: These are only guidelines to assist you. Not all engine conversions are the same.
