macka as far as i understand it; you need the turbo to flow more air, to do this you get a bigger turbo. HOWEVER then you sacrifice driveability (note my 4000rpm spool-up). if i were you id be happy with the car as it is, it is fast! just cos shan's still faster, dont worry well work something out
wait til wednesday and see what times you post down the 1/4 before claiming a lack of power etc. more power doesnt neccessarily make a faster car and if you run a 13.5-13.6 (as you should) then id definately be happy.
then 550cc injectors, Z32 AFM, and 18psi :burnout:
