    Mine had the following :-

    Courtenay Stage 2 re-map
    Courtenay Lower Front Mounted Intercooler
    Courtenay Pre-cat Pipe
    Milltek Cat back Exhaust System
    VXR Turbo
    De-Restricted Air box with K&N Panel filter

    It is worth noting that 260bhp is acheivable with the standard turbo, I only fitted the VXR turbo as the Astra/Zafira VXR and Courtenay stage 2 map run pretty much the same boost levels, so I figured the VXR turbo on mine would not really be working that hard.

    The standard turbo at 260bhp is working flat out.

    The next stage would have been to fit VXR injectors (A must over 270bhp) and Courtenays new stage 4 map, this would acheive an easy 290-295bhp and 330+lb/ft.

    MPG if driven hard was worse of course, but my wife who's car it was did'nt drive hard and the mpg was a little better.

    Regarding the power difference, it was like night and day, all the way throught the rev range the car was brutal compared to standard.

    Matt out of curiosity did you have the actuator changed? I was told by a garage up here the actuator doesnt need to be changed when swapping between the Gsi and VXR turbo's..

    I kept the standard VXR actuator, but I was only running a stage 2 map. Some say you need the uprated actuator for 280+BHP but I am not so sure.
