The Ultimate SR20
From TOMEI POWERED
(The Engine Specialists)
Expreme Thermo Bandage
Bolt Smooth Paste
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
preeminent turbine response
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.
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
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
The EAI correspondence
type TOMEI turbine outlet pipe (Sold separately) can be easily
installed with the use of our exhaust manifold.
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.
EAI compatible model is now available!
