Big Valve Cylinder Heads
For over 40 years, Cosworth has been
the leader in innovative multi-valve
cylinder head design for both racing
and high performance production
cars. The Cosworth CNC Ported Big
Valve Cylinder head range is the latest
advancement. Modified from new OE
cylinder head castings, substantial gas flow
improvements and upgraded valve train
components offer superior performance for
your high performance engine.
Each original cylinder head design is
carefully evaluated and tested to establish
the improvements required to meet
the target performance level. Hours of
testing and flow bench validation are
used to determine the best advanced
port design yielding maximum usable
power and response. However, there
is more to cylinder head design than
just maximum flow. It is critical that port
velocity is maintained to ensure drivability
and valve train components are matched
to guarantee reliable performance. Once
all of these factors have been tested
and validated, the final port contour is
digitized. Using the digitized program, we
then reshape both intake and exhaust
ports using a 5 axis CNC mill producing
an accurate and consistent port shape
every time. In addition to re-shaping and
enlarging the intake and exhaust ports,
most Big Valve Cylinder heads feature

High Performance Short Block Assemblies
Cosworth high performance engine
assemblies are the perfect basis for
your high performance application. Each
version has gone through countless
hours of engineering and evaluation to
determine the best combination of parts
and build specification, ensuring maximum
reliable performance. Each Cosworth
high performance engine assembly starts
with all new select components as the
foundation of the performance build. Every
block is thoroughly inspected before the
cylinders are honed to perfection. We then
balance the rotating assembly that includes
either a new factory forged crankshaft or
Cosworth billet crank along with Cosworth
forged connecting rods, Cosworth tri-metal
bearings and Cosworth forged pistons.
The motorsport grade parts are then
professionally assembled by expert engine
builders in the Cosworth engine assembly
facility. Each high performance engine
assembly includes a complete specification
sheet listing all critical dimensions along
with a serialized plaque. For maximum
performance, combine with a Cosworth
CNC ported Big Valve Cylinder Head and
camshaft set.

then assembled with our Forged Pistons,
motorsport grade Forged H-Beam
connecting rods along with our high
performance rod and main bearings and a
new STI forged crankshaft. For maximum
performance, an optional steel billet crank
is available (CS600X). Once the cylinder
block assembly is completed, we install a
pair of our CNC machine port-bored Big
Valve Cylinder heads with our proven “S2”
camshafts complete with valve lash set to
our specifications. The cylinder heads are
secured with our high performance 11mm
steel studs and sealed with a Cosworth
high performance stopper layer steel
head gasket. Finally, we install one of our
blue-printed, high pressure oil pumps for
maximum lubrication. This proven engine
combination has been used by top teams
to win race and rally events in both North
America, Asia and Europe.

Forged Pistons
With 50 years of world class engine design
and manufacturing experience, Cosworth’s
intimate knowledge of the interaction
between the piston and other engine
components gives the us the distinct
advantage in piston design resulting in the
finest piston available.
The piston is one of the most important
components within the engine. It can be
subjected to directional change up to 285
times every second and must withstand
acceleration forces of 8,500 Gs. Cosworth
high performance forged pistons are
designed and engineered to withstand
this type of punishment and still perform.
All Cosworth pistons are manufactured
using the same methods as our Formula
One pistons and include features such as
anti-scuff skirt coating, ultra-strong pins,
polished top and patented anti-detonation
bands. Additionally, each application uses
a unique forging to minimize weight and
ensure the strongest possible piston.

Cosworth Tech: Green Pistons
Xylan is a fluoropolymer coating
designed for use on various engine
components and fasteners. Cosworth
pistons use xylan coating to provide
lubrication and control friction, wear
resistance, heat resistance, nonstick
and release properties and, at the
same time, can also protect from
corrosion. This is the same coating
we use on many of our ultra-high
performance race engines.

Piston Ring Compressor
Cosworth Cylindrical Ring Compressors
are precision machined to exact tolerance
to ensure easy piston installation on most
engines. They feature a smooth, tapered
bore along with a knurled top ring to
securely hold it in place while installing
the piston. Each tool is machined form
high grade aluminium and features a hard
anodised finish.
Cosworth Tech: Ring Sets
Cosworth Performance Ring Sets are comprised of a chrome top ring, an iron second
ring, and three-piece oil ring. Some Cosworth Performance Ring Sets offer upper
rings that are gas nitride treated for quicker break-in, lower wear, and improved
sealing. Manufacturing tolerances exceed OEM standards. Axial tolerance is +/0.0002” and radial tolerance is +/- 0.0005”.

Billet Crankshafts
Increased engine performance often
means increased engine speed and load.
Original factory crankshafts may not
be able to withstand the added stress,
resulting in catastrophic engine failure.
Additionally, many OE crankshafts rod
journals are lubricated from only one
main oil feed. Cosworth billet crankshafts
feature full-flow oiling whereby each
rod journal is lubricated from two main
sources. This provides superior lubrication
during sustained high rpm use preventing
rod bearing failure. Cosworth Subaru
crankshafts are manufactured entirely from
high grade steel in a light-weight, high
strength design with a unique Isotropic
Super Finish (ISF®).

Cosworth Tech: Isotropic Super Finish (ISF®)
The ISF® process is a chemically
accelerated vibratory mass finishing
process. Any time two metal parts come
into contact with each other, the resulting
friction causes heat build up. These high
temperatures cause wear and over time
reduce efficiency and eventually create
the need for replacement. By creating
a smooth and shiny finish, the ISF®

process improves the life and efficiency
of moving metal parts. Increased life
translates into lower operating costs as
well as better performance. In extreme
environments, such as automobile or
motorcycle racing, every component
must work in harmony at 100% capacity.
Races are won and lost by fractions of a
second, so it all comes down to getting
Allows a freer movement of parts with
less surface resistance

the most power output possible. With the
ISF® process, the energy normally lost
to friction is now available in the form of
increased power output. Once friction
is reduced, the engine will run cooler
allowing for longer durability of parts and
fewer failures.

Cosworth Tech - Subaru Cams
Our Subaru AVCS cams are available for both North American and Japanese/European
applications. While cam profiles are the same, cam angle triggers are significantly
different. AVCS camshafts for North American applications use a series of three slots
to activate the cam angle sensor. Japanese/European applications rely on four raised
triggers to activate the sensor. If in doubt, check your original cams before ordering.

Size 1 is what we used to call “STD”
Size 2 is what we used to call “RACE”
Size 0 provides .025mm or .001” less oil
clearance than our size 1 bearing
Size 2 provides .025mm or .001” more
oil clearance than our size 1 bearing
Bearing half shells can be mixed and match
to provide the incremental changes in oil
clearance However it is imperative that
bearing clearances are measured before
selecting the appropriate bearing size.

TGV Delete Kit - PN 20015678
The Cosworth Tumble Generating Valve
(TGV) Delete Kit is designed to maximize
airflow to your engine by eliminating the
obstructions inherent to the OEM TGV
intake ports. The TGV deletes are made
of a fibre reinforced polymer to insulate
the cylinder head from the intake tract,
providing your engine with a cooler,
denser charge of air. To further increase
performance, the Cosworth TGV deletes
are port matched to our CNC cylinder
heads and intake manifold. This product
is a direct fit for the 07+ Subaru STi due
to the top feed injector design and due
to a revision to the upper bolt pattern of
the TGV, specifically moving the centre
two M6 holes. With our manifold and
top feed injectors, the TGV delete kit will
work without issue on most WRX/STi
applications

Brake Pads
The racing performance pedigree that
is so much part of Cosworth’s heritage,
is clearly demonstrated in this exciting
addition of brake pads to our Aftermarket
Performance Parts range.
With two grades of friction material, the
StreetMaster and TrackMaster ranges
deliver exceptional levels of stopping power
specifically tailored for fast road and track
applications respectively.
Manufactured in the United Kingdom,
Cosworth brake pads feature a 1.5mm
granulated interlayer which not only serves
to act as a shock absorber, helping to
reduce stress on the rotor surface but
triples bonding strength so diminishing
edge lifting.
To reduce the “bedding-in” or “seatingin” time - this is the time it takes for the
pad and disc to adapt to each other - all
Cosworth brake pads are heat seared.
This process heats the friction material
to in excess of 600°C “toasting” the
surface greatly enhancing the performance
the first time that the driver applies the
brakes. Scorching pads also significantly
reduces initial fading. Fading increases the
necessary force and pressure required to
maintain the deceleration of the vehicle.
Cosworth’s brake pads range offer
exceptional performance with no
compromise.

The Cosworth BBK calipers are 6 piston,
with differential bores to eliminate “pad
taper”. The trailing pistons have a larger
bore than the leading ones to compensate
for mechanical end load & to even out the
wear on the pads. All our performance
brake calipers use conventional seals
in conjunction with a dirt seal and are
finished with an eye-catching high gloss
black PTFE based paint coating which is
impervious to normal brake fluids & high
brake temperatures.
The 2-piece discs features Cosworth
technology embedded within the pair of 48
vaned discs together with lightweight high
grade aluminium mounting bells designed
to deliver enhanced airflow than the original
brakes. The discs have been developed to
produce optimum braking bite, as well as
thermal stability and durability.
The upgrade kits also contain a set of
high performance brake pads, mounting
brackets individually designed for each
application, brake hoses, a complete set
of fixings and two bottles of AP Racing
Formula DOT 5.1 brake and clutch fluid.

Oil Control
Subaru Dry Sump - 20004463
The Cosworth Dry Sump Setup Kit for the
Subaru EJ series engine is a must for race
and performance applications. Dry sump
oiling systems offer an unparalleled level of
safety and reliability compared to factory
wet sump systems. Complete crankcase
oil scavenging reduces excessive and
residual oil that can cause blow-by and
power loss. A dry sump also offers more
consistent oil pressure to the engine,
improved scavenging, and increased
ring seal due to greater pan vacuum.
The Cosworth Dry Sump System for the
Subaru EJ20/EJ25 replaces the original
oil sump with a machined from solid, low
profile alloy pan with twin scavenge ports,
internal baffling and o-ring sealing. A two
stage scavenge pump driven by a HTD
belt, mounted to a heavy duty bracket
evacuates the oil from the engine.

High performance engines reject a
substantial amount of heat through the
oil system. Maintaining oil pressure and
control along with an increase in actual
volume will help dissipate heat and stabilise
oil temperatures. Cosworth oil control
components are engineered to combat
several problem areas experienced in high
performance engines.
Mitsubishi 4G63 Crankscraper
The Cosworth 4G63 Crankscraper is
engineered to reduce parasitic drag on the
crankshaft caused by oil accumulation that
surrounds the crankshaft during rotation.
This oil buildup causes additional drag and
can reduce power output. Additionally,
overall oil control is improved by keeping
oil in the sump. Especially useful in high
rpm and race applications. Mounts to main
bearing girdle. Designed from 2.6 mm
(12gauge) steel plate and includes required
mounting hardware.

Nissan Oil Control Baffle
The Cosworth Oil Control Baffle for the
Nissan VQ35 has been engineered to stop
oil from surging away from the oil pick
up during hard driving conditions. The
unique Cosworth one-way control valves
allow oil to flow towards the pickup but
restrict oil from migrating to the back of
the sump during aggressive manoeuvres
to help maintain constant oil pressure.
Manufactured from stainless steel.
Model Year 2003-2004 require fit kit PN
20008632 for proper installation.
Subaru Oil Pan Baffle
Oil control can be a problem with high
performance and high revving Subaru
engines. High crankcase pressure along
with the horizontal engine platform restricts
rapid oil return from the cylinder heads to
the oil pan. Pressure builds in the heads
and crankcase causing massive blow by
and power loss. The Cosworth Subaru
Oil Pan Baffle has been engineered with
diverters to control oil returning from the
cylinder heads to the pan directing it away
from the crankshaft. Additionally, oneway valves prevent oil from re-entering the
upper crankcase chamber thereby limiting
blow by and preventing oil starvation during
hard driving. Manufactured from stainless
steel and installs easily between the block
and oil pan on both EJ20/EJ25 series
engines. Use with our High Volume Oil Pan
for maximum oil control.

Subaru EJ20/25 High Volume Oil Pan 20001238
Sustained high RPM or prolonged high
speed driving will result in elevated oil
temperatures. Additional oil volume along
with improved oil control will reduce
damaging oil temperatures. The Cosworth
EJ20/EJ25 High Volume Oil Pan is
fabricated from both custom and original
components resulting in an additional 2qts
oil capacity when compared to standard
oil pan. Each kit includes powder coated
oil pan, mounting hardware, oil pickup and
spacer. Will not work with some equal
length exhaust manifolds.
Subaru EJ20/25 Oil pump - High Volume, High Pressure - 20001185
Increasing oil volume will help to prevent

Additionally, sustained high RPM use may
cause oil starvation at the rod and main
bearings. The Cosworth High Volume
Subaru EJ20/EJ25 series oil pump
utilizes a completely new inner and outer
12mm rotor to increase volume by 20%.
Suggested applications include drag, track
day and race use. Each kit includes all
required mounting hardware and seals.

Thermal Composite Gaskets
The Cosworth Thermal Guard Composite
Intake Gasket is designed to aid in the
reduction of inlet air temperature by
isolating the intake manifold from the heat
generated by the engine’s cylinder head.
By reducing the temperature of the inlet
manifold the temperature of the intake air
charge is also reduced. The density of
cooler air is greater than that of warm air.
A denser intake air charge contains more
oxygen which results in the potential for
increased power and torque.
Each Cosworth Thermal Guard Composite
Intake Gasket is precision manufactured
from an engineering grade composite
phenolic material that resists deformation
common with plastic gaskets. As an
added feature Cosworth Thermal Guard
Composite Intake Gaskets are reusable
and include a tube of “Hylomar Universal
Blue Racing Formula” sealant. The use of
OE inlet manifold gaskets is not required
with the Cosworth Thermal Guard
Composite Intake Gasket.

Cosworth Rhino Skin - Thermal Heat Protection
Cosworth Rhino Skin is a simple yet
highly effective way of restraining heat
from penetrating and destroying thermally
sensitive areas of the engine bay - a
re-occurring challenge for fast road and
motorsport vehicles.

Cosworth Rhino Skin has been initially
developed as thermal protection for two
key areas: turbochargers and exhaust
manifolds where temperatures typically
exceed 900°C/1650°F, making the need
for predictable, rugged and reliable thermal
armour a real one.
CRS008
Honda K20A EP3 exhaust manifold heat shield
Cosworth Rhino skins are designed for
street performance to hardcore motorsport
applications. Branded in Cosworth
image, each skin has a Teflon style
surface effectively repelling grease and
dirt they are capable of withstanding upto
1250°C/1800°F continuously.
Wrapping the exhaust header with Rhino
Skin maintains hotter exhaust gases,
decreases the density, and allows the
exhaust gas to accelerate from the system
quicker. Thus, greater exhaust scavenging
is produced lowering intake temperatures
and in-turn contributing to an increase in
power.
Benefits to power are also demonstrated in
vehicles like the Subaru Impreza where the
intercooler sits on top of the engine, rather
than down at the front by the radiator. The
“Up-Pipe” that brings hot exhaust gases to
power the turbo and the “Down-Pipe” that
takes them away, are both located directly
beneath the intercooler - clearly generating
significant radiant heat, particularly when
the car is stationary.
To overcome this, a solution successfully
developed and employed on the Cosworth
Impreza CS400, was the Rhino Skin
application – using the Rhino Skin to
prevent the exhaust transferring heat to the
intercooler, keeping the charge cool and
improving the car’s performance and also
increasing the engine’s responsiveness.
From the turbo perspective, the benefit
of the shield is that it stops the turbo
cooling down too quickly, preventing rapid
temperature change which can cause
turbine damage.
