Perhaps are largest amount of
e-mail questions and phone calls is based on the requirements to install an LS1
into a 3.4/3.8 equipped F-body. Unless you decide to wire it yourself, you
will need the entire chart below***. The swap is broken down into 2
charts. The first chart is a requirement regardless of year, meaning all
the parts are required for installation. The second chart is year
specific, meaning that you will need to specifically change those parts based on
the year of the donor engine/transmission. You will need these parts in
addition to the first chart. Generally speaking, we suggest having an
entire donor car for the swap.
Mandatory components required for the
swap
| Component |
Reason |
| Complete engine
assembly |
Every component is different.
Nothing interchanges with the motors. |
| Transmission |
The Bolt pattern is completely
different from V6 to V8 |
| Engine Cradle |
An LS1 engine cradle is formed
different to sit lower. The use of the LS1 mounts is also
required. |
| Radiator
|
The LS1 radiator uses an additional
steam line on the RH tank. Early LS1's also use a low coolant
sensor. |
| Fuel Pump Assembly |
Although the V6's and V8's operate
at the same PSI, the V8's use a higher volume. 99-02 LS1's
have the fuel regulator built into the tank. |
| Gauge Cluster |
The speed reading is different, and
the tach reading is different. Not changing the clusters will
cause the tach reading to be erratic. Oil PSI and water
temperature readings are also different. |
| Harnesses |
The engine harness & PCM are all
required changes. |
| Hoses |
The LS1's coolant
hoses are in different locations. The A/C hose is also different. |
| Throttle System |
The throttle cables need to be
changes since the LS1 cable is mounted on the RH side. 99-02 3.8
equipped cars will require the addition of a mechanical accelerator
pedal since they are electronic on the 3.8 |
| Suspension
|
LS1 coil springs are required from
the added weight. Your vehicle will sit low if you do not change
the springs, but also have poor handling since springs are rated for a
certain weight. The steering rack is also different to clear the
oil pan & alternator. |

Legend : Y = Yes (Requires Change), N
= No (Requires no change)
-
F (Cooling Fans) - LS1's
use dual cooling fans.
-
A (Airbag Sensors) - 93-95
models use a 3 sensor system, 96-02 use a single sensor system. The
connectors are physically different as well on 99-02 models.
-
D (Dash Assembly) - 97-02
uses a totally different dash VS the 93-96 Camaros. Firebird remains
interchangeable.
-
W (Wiring) - All the
wiring (Relay harness, dash harness, etc).
-
B (Brakes) - The LS1's
use a different braking system for the increase power. The braking
system includes the spindles, calipers, ABS unit and controller.
***Note -
Swaps can be performed in many methods, including and excluding many
parts. The charts above are just suggestions of the staff at Trans Am
Creations for proper trouble free installation and reliability.
