Our EXPREME exhaust manifold is now
available for SR20 owners who want a performance
upgraded from the genuine exhaust manifold. With our
product you can retain the genuine setup and no special
modifications are needed to fit the standard turbo. With
the SR20DET the exhaust manifold was designed to be
close from the exhaust port to the turbine. With the
comparison test of our isometric prototype & the factory
genuine manifold which also utilizes the same layout, it
shows that ours has succeeded in delivering an overall
improved performance in both torque and power increase
in areas like in the higher RPM range in which you were
not able to utilize before. With our extensive testing
we have reached the conclusion that the normal design is
superior as a total overall efficiency. So to develop an
exhaust manifold similar with the design and setup as
the factory manifold we were finally able to produce a
product worthy to bear our name as a product that has
the potential to deliver an overall increase in
performance.

Acquiring the preeminent turbine response, by
utilizing a short piping layout. |

2. Excessive
anti-pressure rise is prevented even at high RPMs. Ideal
exhaust efficiency is obtained. |

TOMEI EXPREMEs exhaust manifold
for the SR20 is designed with a partition plate
inside the 1st & 4th turbine side ports as the
2nd & 3rd are divided for the exhaust ports. The
sequential ignition firing order of the SR20
(1-3-4-2) can cause exhaust interference. The
exhaust is discharged from both left and right
of the partition plate and can cause to happen
where the pipes all merge together. Now TOMEI
has found the best possible exhaust flow.

3. Support Bracket |
 |
The support bracket is included, so
there is no need to worry about the products
strength. |
|
| |
|
4. EXPREME Thermo
Bandage. |
 |
Heatproof for temperatures of up
to 1100℃and dissipating 90% or more of heat
effectively. Helps you extract more power from
your engine by reducing the oil temperature and
also the engine bays temperature which can
affect the air intake temperature as well.

5. Japans Vehicle
Road Inspection System. |
|
This is compatible with the (R)
PS13 EAI mechanism and blow-by separator. The
EXPREME Bandage is also included in the kit to
comply with the Japanese street legal road
regulations for the vehicle inspection.

Our outlet pipe (dump pipe) was
made larger for assured exhaust ratio
improvement, the instability and deterioration
of supercharging pressure decreases the response
of power from the secondary exhaust pressure
which can cause a substantial decrease.
