So stage 2 upgrade costs rough pricing (I used some old data but it's ball park) on an LCR

here are 3 interesting options..........
Overall cost is circa £2k
Option1 - Stage 2 - Overall 270 ish bhp
Revo Stage 1 (+ Stage 2 upgrade) - Approx £636 inc VAT
Milltek exhaust with 100 cell race catalyst & DP or / and maybe FMIC - Approx £1200 inc VAT
Forge DV 007P - Approx £80 inc VAT
Dynatwist induction kit (with air intake hose located in nearside wing above intercooler) - Approx £180 inc VAT
Forge TIP - About £100 inc VAT
What else could £2k get you apart from 2 weeks in Barbados
Option 2 - Stage 1+ Overall 260ish bhp
Revo Stage 1 - Approx £580 inc VAT
Coilovers (good quality not crap) £700 inc VAT
ARB's £350 inc VAT & Del
Fitting £250 approx
Forge DV 007P - Approx £80 inc VAT
Option 3 - Stage 1++ Overall 260ish bhp
Revo Stage 1 - Approx £580 inc VAT
Quaife ATB - fitted £1200 (approx)
Forge DV 007P - Approx £80 inc VAT
Rear ARB fitted say £250 in VAT
Any of the three solutions is en-route to Big turbo so each is just as valid in that context.
On the road though I'd bet the second 2 are faster in the real world
