ENGINE BREATHER SYSTEM (R300 AND
R400 WET SUMP ONLY)
1 The engine breather is connected via
rubber hoses to a separate catch tank located
on the RH upper engine bay side rail.
2 Secure the breather catch tank to the RH
upper engine bay side rail (square tube) above
the steering rack.
3 Fit the right angle rubbers to the
protruding breather outlets, located side by side,
on the cam cover of the engine.
WARNING
Use appropriate eye protection whilst
carrying out drilling operations.
4 Route the rubber hose to the breather
catch tank. Drill two 13 mm holes in the side of
the catch tank approximately 20 mm from the
top. Insert the rubber tubing from the breather
outlets to a depth of 50 mm.
5 Drill five 5 mm holes in the black plastic
lid, this prevents build up of gas in the catch
tank, and fit the lid to the catch tank.
6 Secure the right angle rubbers to the
breather outlets using cable ties.
NOTE
The breather systems for a dry sump car is
different to that described above.
COMPETITION EXHAUST SYSTEM
7 Unlike the standard K-Series manifold, the
competition exhaust system utilises individual
primary pipes.
8 Protect the paint work around the exhaust
aperture in the body skin using masking tape.
Fit the gasket to the engine ensuring that any
masking tape covering the exhaust ports is
removed. Place each primary through the
exhaust aperture and fasten loosely into
position.
9 Slide the collector/catalyst over the
primaries and ensure that the securing tabs are
aligned. Secure using bolt (fastener pack
ZEX02, Item (2)). Plain washers (7). Spring
washers (8) and plain nuts (4). Do not tighten.
10 Fit the Lambda probe into the threaded
boss in the catalyst. Ensure that the blanking
plug fitted into the boss in number four primary
is secure. Secure the Lambda probe wiring with
cable ties ensuring it cannot contact the
exhaust.
11 Undo the large clips and feed them
through the guides on the inside of the small
aluminium catalyst guard. Fit the guard to the
catalyst body and relink the hose clips. Tighten
the hose clips to secure the guard.
12 Fit the exhaust mounting bracket.
Section 9, Para 52 refers.
13 Position the exhaust clamp over the
exhaust pipe and slide the silencer assembly
over the collector/catalyst exhaust pipe. This
may be a tight fit but twisting the silencer will
help. Attach the rear of the silencer to the body
mounting using nut (3) and spring washer (6).
Tighten all fastenings working from front to back.
14 Fit the guard to the silencer as detailed in
Para 11 using hose clips provided.
DRY SUMP SYSTEM
15 The dry sump system retains the original
internal pump as a pressure pump with an
externally mounted scavenge pump located on
the RH side of the engine in a cast aluminium
cradle. The bell-housing also incorporates the
oil tank for the system.
Fitment of dry sump equipment to belltank-
housing
16 The belltank-housing is a complicated
casting. Although the casting has been
pressure washed by the manufacturer, there is a
possibility that some sand may remain in the oil
tank, it is vital, therefore that the inside is
checked and any sand residue is dislodged and
removed using a small stiff brush.
