Staged Upgrades

[bradc]

Most other car related sites have a list of staged upgrades, we don't! I've put this list together today, note that this is it's first draft and not a set of rules. I want to see what others have to say. Also not too sure if things like springs and wheels should or shouldn't be included, let me know what you want! It isn't going to focus much on maintaining the car, everyone who is modifying their car should have nothing but Fully Synthetic (capitalised intentionally) 0w30 oil that is less than 5000km old at all times, a functioning O2 sensor, clean driveline oils, etc.

1st Stage:

Cat-back exhaust system
Decat (if legal in your country)
Manual Boost Controller, Boost Gauge (optional)
Replace Spark Plugs and check Leads

2nd Stage:

K&N or Ralliart Panel Filter
Downpipes
Upgraded Intercooler
Replace Stock Blow Off Valve

3rd Stage:

17-18" wheels, aim for around 8" wide and 35-40mm offset. Allow for Brembo clearance if you are considering them
EBC Red pads (or similar) for fast road driving or Carbotech's for track use
Replacement Springs or full Coil Over system

4th Stage:

Hard Piping kit - possibly combine with Cold Air Box and Battery to boot
Fuel Pump such as Walbro or similar
Rear upper strut brace (Legnum's Only)

5th Stage:

Fuel Controller, Piggy Back or Full ECU
Fuel Pressure Regulator
Removal of MAF and change to MAP with compatible ECU's

6th Stage:

Turbo Upgrade
Forged Internals
Larger Fuel Injectors
(no need for further explanation, most people should be smart enough to do their own research at this stage)
