Cordia GSR Turbo Performance Modifications |
The Mitsubishi Cordia Turbo is quite a capable
car in stock trim but with minor modifications the Cordia Turbo
can be a real traffic light frightener. The most common
performance modifications preformed to a Cordia Turbo is an
exhaust system upgrade, air filter upgrade and an increase in
boost. |
|
All stock Cordia Turbos can benefit from a little
more boost but firstly a larger exhaust system needs to be fitted
to ensure smooth power delivery throughout the rev range after
boost is increased. Any straight through exhaust system equal to
or larger than 2 1/4 inch is necessary. The muffler must be a
straight through type or else the benefit of the larger exhaust
pipe will be minimal. For the AC model, a high flow catalytic
converter needs to be fitted, preferably of the same size as the
exhaust pipe. Then boost can be safely increased to about 10 psi.
The cost of a full 2 1/4 inch exhaust system should set you back
about $350AUD to $450AUD plus the catalytic converter if
necessary. Any reputable turbo specialist can increase boost with
the installation of a bleed valve for the cost of about $120AUD. |

Once these modifications are done, power for the
AC model should increase from about 61kw to 76-86kw at the wheels
with the exhaust and 10psi boost. The AA and AB models should
increase from about 66kw to 83-93kw at the wheels. Also bear in
mind that dynos can differ greatly from place to place and are not
a good source for comparing cars. The main difference between the
models is mainly due to the catalytic converter, lower octane
unleaded fuel and smaller turbo on the AC model. |

If power is still not enough for you an
intercooler needs to be installed. In some cases the air
conditioning system needs to be removed so the intercooler and
piping can be easily mounted forward of the air conditioning
condenser at the front of the car although this may only apply to
larger intercoolers. A brand new custom intercooler setup will
cost about $1200AUD to $3000AUD depending on size so the best
option is to go for a second hand one. The Nissan 200SX, RX7 or
Toyota Supra intercoolers are usually good options as they fit
quite well without too much hassle. Depending on the experience of
the fitter it should cost you around $500AUD to $1000AUD for both
the mounting and piping. |

After the installation of the
intercooler, boost can then be safely increased to about 14 or
15psi. Boost can be increased further but the injectors and fuel
pump need to be replaced and some engine components may also need
upgrading. If you are planning on going this far the most cost
effective option would be to go for the Mitsubishi VR4 4G63BT
1997cc DOHC 4-cyl turbo motor. This will give you an instant 148kw
(Australian Spec) at the flywheel plus the extra torque of the 2
litre motor. The cost of the engine and fitting will cost you
about $3500AUD to $4500AUD. With a good exhaust, intercooler, blow
off valve and increase in boost 200kw to 220kw is easily
achievable at the flywheel. All this for around $5500AUD. The
Cordia Turbo will then become a real beast. You could even
possibly blow away Lancer GSRs and WRXs. Not bad for a mid 1980s
car. |
