For convienience and when the fccuk forum is offline I have copied data and links across.
TUNING STAGES 20VT - [courtesy of Hanny @ fccuk forum]Original Text Stage 0 - Health Check - 220BHP
a)Get a proper engine health check including fuelling, and engine performance as well as compression test each cylinder
b)Get car fully serviced, inc coolant changes etc
c)Base-line dyno figures
Stage 1 - Basic Preparation & modifications - 230-235BHP
a)Boost gauge
b)Boost control (PRV, PBV or electronic boost controller)
c)Induction modifications (eg. drilled airbox, intake cone etc)
d)Dump valve upgrade (stop turbo stalling
e)Crankcase breather filter (stop contamination of inlet tract)
f)Water wetter (increase reduction in water temperatures)
Stage 2 - Turbo ancillaries - 240-250BHP
a) 2.5", 2.75" or 3" exhaust (less backpressure)
b) Decat or sports cat (less backpressure)
c) Uprated side mount intercooler (lower charge temperature)
d)* Water injection (lower charge temp, more advance)
Stage 3 - Chipping - 250-270BHP
a) G-Tec chip (more power) or a Unichip
b) Uprated fuel regulator (more fuel pressure)
c)* Hybrid turbo - i.e. standard casing
Stage 4 - Improving ancillaries - 260-280BHP
a) uprated clutch
b) uprated fuel pump (More fuel)
c) lightened balanced flywheel
d) FMIC and/or chargecooler
Stage 5 - Uprated turbo - 280-300BHP
a) Uprated turbo (eg. the ball bearing range Barbz is doing)
b)* Cams
Stage 6 - Advanced tuning - 300-350BHP
a)custom mapping eg. Motec (tailor ECU to modifications)
b)Uprated fuel injectors
c)* Nitrous
d) Intercooler hard pipe kit
e) intake hard pipe kit
* would denote these are things you might want to consider but may not be worthwhile
You might also have stages for non-engine stuff that should be done with the corresponding tuning level, such as
Stage 0 - Health Check
a) Check wear on all suspension parts
Stage 1 - Basic Handling
a) Strut brace
Stage 2 - Stopping power
a) Uprated front discs and pads
b) Braided brake hoses
c) Bleed brakes and put new fluid in
Stage 3 - Suspension
a)* Lowered
b) Uprated dampers
c) Uprated bumpstops
Stage 4 - Advanced Handling
a) Uprated anti-roll bar
b)*Camber adjustment (if no negative camber provided by dampers)
Stage 5 - Dynamics
a)* lighter wheels
b) wider tyres (225 profile)
c)* 5mm hubcentric spacers (wider track for standard alloys only)
Stage 6 - Advanced suspension
a) coilover suspension
b) polyurethane dampers
