MAINTAINING YOUR OLD FORD
aluminium, the new housing costs £96. Budget for
around £6 for an oil filter.
EXHAUST MANIFOLD
Developed to fit into their Zero kit car, and
incorporating the threads for a lambda sensor,
this 301 stainless-steel exhaust manifold costs
£199.20 and may be suitable for some engine
transplants. Check with GBS before ordering.
WATER PUMP PULLEY
A 20% larger water pump pulley is available
from GBS, which is machined from 6082 T6-
grade aluminium that’s not only lighter than a
standard steel pulley, it also promises to be better
balanced. GBS have identified that at high engine
revs, the water pump pulley is spun at such a
speed that it can cause fluid cavitation to occur
at the pump impeller, which results in a reduced
flow of coolant, excessive vibration (resulting in
premature seal/bearing failure), and damage to
the water pump’s impeller blades and its housing.
By fitting this larger pulley, it slows down the
rotation of the water pump and thus helps to
reduce the risk of the aforementioned problems.
Available in black, orange or silver and priced at
£65.48.
GEARBOX OPTIONS
Mazda’s M53F five-speed manual gearbox
can be fitted onto the 2.5 Duratec without any
adaptor plates or modifications. This was fitted to
the Mazda MX-5 (NC or Mk3 model). Budget for
around £300 for a second-hand gearbox, or GBS
sell new ones for £1,250.
ENGINE SUMP
The standard Duratec sump is deep and may
reduce ground clearance on an engine installation.
GBS manufacture a shallower sump, which is
manufactured from aluminium and includes
internal baffles to help reduce the risk of oil
starvation. They are also working on a range of
sumps to fit different applications including the
Mk1 and Mk2 Escort. Their current shallow sumps
require a shortened oil pickup pipe to be fitted, the
balance shafts removed and an oil blanking bung
to be fitted.
AUXILIARY DRIVEBELT IDLER
A better-looking five-groove aluminium idler
pulley for the auxiliary drivebelt helps to brighten
up the front of the engine. Priced at £47 and
available in silver, black or orange.
ALTERNATOR PULLEY
An aluminium five-groove pulley for the
alternator, which is available in silver, black or
orange and costs £36. Requires the alternator’s
old pulley to be removed with special tools
available from Halfords, Sealey, Laser and Euro
Car Parts for around £20 or more. n
