The cooling system on the XR4Ti is fairly unique. If there is
another car with more individual hoses in the cooling system,
we have yet to see it. Compound this with the changes
throughout the model run and it gets even more complex. We
have a good inventory of the hoses and other cooling related
components that fit 1985-87 XR4Ti and some (where similar
or noted) for 88-1989 cars.

Cooling System (Scorpio)
In addition to our stock of cooling system components for the XR4Ti
we have added the various Scorpio related items to our inventory.
The Scorpio's cooling system is only slightly less complicated than
the XR4Ti's, it's only saving grace is the parts do not vary all that
much from year to year. Again, as with the XR4, components that
we offer are from the O.E. supplier or Ford originals.

pA Standard Wastegate Actuator Since the stock XR
wastegate is no longer available new, we supply a high quality
re manufactured unit. Internal components (diaphragm) are re-
placed and exterior is zinc plated.) M521WR
pB
Turbochargers We offer both re manufactured stock
specification and modified high performance turbos for the
XR. High quality re manufactured turbos include; new center
cartridge compressor/turbine wheel assembly with recondi-
tioned outer compressor/turbine housings, new bearings,
seals and O-rings and fasteners. Our high performance turbo
adds a few extra tweeks. A GNX compressor wheel machined
into the stock comp housing for an additional 30% airflow and
a 360 degree thrust bearing is fitted for added durability.
Turbos are fully dressed and include wastegate actuator,
base & drain gaskets and sold on a exchange "core" basis-
outright purchase will add an additional $100.00 to the cost.

High Performance Turbocharger M522TM
pC
Intercooler Kit If you are looking for a large high flow
intercooler kit this is the one to have. Intercooler core mounts
ahead of the steering rack in front of the engine facing the
ground. Air is ducted up and through the core. Plumbing is kept
short and allows for a larger core than what can usually be fitted
in the bumper/grille area. Kit is complete with intercooler core
(8" x 20" x 3.5"), mounting brackets, inlet plumbing pipes &
connectors, clamps, turbo output elbow, bypass valve and
additional hardware and instructions.
M522ICpD
Adjustable Boost Valve Kit Replace the troublesome
stock boost control solenoid with this easy to adjust under hood
boost valve. This kit uses a check valve to accurately control the
boost level which allows for faster turbo spool-up (reduced lag)
over typical adjustable "bleed-off" valves. This is a low cost modifi-
cation and should be a "must have" for all XR's.
M521BV
pE
Dual Port Wastegate Actuator These are new actua-
tors which feature an adjustable length rod (set boost & pre load)
and dual vacuum ports. The dual port feature permits use of a
remote mounted boost valve (see below), but can also be used
as a replacement for stock actuator.
M521WA2
pF
Cockpit Mounted Boost Valve Remote cockpit
mounted adjustable boost valve for use with dual port wastegate
actuators (see above). Vacuum signal is regulated by the in
car mounted valve and recirculated to the dual port actuator for
precise adjustment. M521TB
pG
Turbo Oil Feed Pipe is prone to cracking/leaking and
should always be replaced when a new turbo is fitted to assure
proper oil flow. Just look inside an old one and you will see
what we mean. M522P
pH
Turbo Inlet Hose we have a version of this (discontin-
ued by Ford) hose that links the turbo outlet pipe to the throttle
body. Ours is high specification 4-ply Silicone (blue) rated to
over 600 degrees, 190 psi burst pressure- better & cheaper
than the original ! M22H

Stainless Base Gasket replacement for between the turbo
base and exhaust manifold. L521GT

Transmission & Related Components
pHShifter- A serious short throw competition gear lever
featuring a robust large diameter shaft placed within a
spherical bearing. The all metal construction will cause
additional transmitted noise but this is a small penalty to
pay against the strength, speed and quality of the gear
change achieved. M717
pIGear Oil- Torco synthetic gear oil is designed to
withstand tremendous heat and provide extreme anti-
score protection under high torque "shock loading"
conditions. That is why most Indy car and drag race teams
rely on Torco protection. Torco SAE 75w90 gear oil is GL-
6 rated and includes limited slip additives. Great for both
transmission and differential applications. Torco synthetic
gear oil greatly improves the shift "feel" of T9 transmission,
shifting becomes light and precise, almost like a tune-up in
a bottle. Notes: transmission will require 2 quarts (2.25 to
3.34 pint capacity depending on year) and rear axle 1 quart
(1.6 pint capacity) Gear oil not for T5 transmissions (use
ATF type fluid). C2S
pJQuadrant & Pawl Kit- When the clutch pedal "ratchet
adjuster" wears out it contributes to poor pedal feel and an
annoying clicking noise. Renewing the quadrant and pawl with
this handy kit will alleviate the problem. M368
pK Rebuilt T9 Transmissions- Highest quality factory
certified remanufactured T9 transmissions with European
gear ratios (3.65:1, 1.97:1, 1.37:1, 1.00:1, 0.82:1). M700

pG Short Shift Kit- If anything can be added to enhance
the "link" between driver and transmission while rowing through
the gears on the XR4 or Scorpio 5-speed this is it. We have a
dynamite quick shift kit that fits standard T9 Hummer transmis-
sions. If you like the shifter "feel" on Hurst equipped Mustang
GT, this kit offers similar results. Customers often remark that
this shift kit is one of the best modifications that they have made
to their cars, especially considering the price and ease of
installation. Just think about how many gear changes you make
in a day, let alone a week, or year. Shouldn't every shift be quick,
light and precise? M715
