If you have a 3F/3FE equipped Land Cruiser and
are looking to maximize it’s performance. If you have taken the effort to
build a 2FE Hybrid engine, or you’re simply a “motor head” and want your 3F
to perform to it’s ultimate potential, here is where to start. Our Tuned,
Ceramic coated, equal length headers are one of the most effective
modifications you can make. Our headers will maximize the performance and
efficiency of any 3F engine. This is one of the very rare modifications you
can perform on your 3F engine that will deliver
improved performance and efficiency at every rpm, and every throttle
position.

Our flanges are blanchard ground to a thickness of .5925” to match the OEM
intake manifold. The fact that our flanges are over ˝” thick steel negates
any of the typical problems associated with headers that use thin flanges
that are prone to warping and leaking. By using a flange that is flat on the
gasket contact surface, we are able to use an OEM type manifold gasket with
these headers.
Our primary tubes are 1-3/8” ID. The reason we chose these dimensions is the
basic design of the 3FE engine. These engines are designed to produce low to
mid range torque, and our headers are designed to maximize this type of
torque curve. From the immediate application of throttle at idle, all the
way to the limit of the rpm band our headers improve performance and
efficiency. Our design delivers the ideal length primary tubes, while
keeping collectors and connecting pipes high in relation to the chassis.
Although our headers will fit any 3F/3FE engine, regardless of the body
configuration it is in, we designed our headers to fit within the confines
of the 62 series engine compartment. Our connecting pipes available in bare
steel or ceramic coated steel, connect directly to your OEM FJ62 catalytic
convertors in their OEM location , and will remount your O2 sensors in their
stock location, using stock gaskets. Your EGR pipe will also directly
reconnect to our headers. Basically all your emission equipment can
stay connected if you so desire. We also offer weld on connecting flanges
for those that want to run these headers on other body style vehicles or
want to custom build their own exhaust.
Ceramic coating for heat retention. Although ceramic coating tends to
improve the looks of our headers the technical purpose is to help keep the
exhaust heat in the exhaust system, not radiating into the engine
compartment. Headers by the nature if their design have more surface area
than the cast iron manifolds they replace. More surface area equals greater
heat transfer potential. Ceramic coating slows this transfer and helps keep
the heat in the exhaust system, which improves catalytic convertor
efficiency.
3F/3FE headers are sold as a kit that includes a new manifold gasket, and
hardware for the lower connector flanges. Our connecting pipe kits include
either bare steel or ceramic coated pipes, seal ring gaskets for the pipes
to OEM Catalytic convertors, new oxygen sensor gaskets, and bolts for the
pipes to the cats. Please note manifold gasket is for fuel injected 3FE
engines. Manifold gasket for carbureted 3F engines available separately.
We now offer our 3F/3FE Headers in bare steel.
