try stage 1 first as as stage 2 requires alot of money tbh
you'll need a good TBE could cost up to 1k
good induction kit up to 350
uprated brakes up to 500
uprated hpfp up to 800
uprated clutch + cover+ new dmf up to 1k
your looking at over 4k easy
Stage 2 requires a downpipe only...
2+ requires the HPFP and induction.
Brakes i recommend if your standard!
Clutch not sure on as im rocking dsg.
