I haven't just changed the turbo and i did look at the GT20/25 conversion but the turbo which i got built for me i have been told its better than that and with no Lag its just IHI 5 housing with different parts 360 ball bearings and some other parts i dont quite understand lol, Also iv got a Larger Front mounted Intercooler, Induction Kit is the Sanspeed one but Customised to draw the cold in from where the old intercoolers were, Exhaust staying the same but Decat, Uprated Drive Shaft, Uprated Clutch And the old Boost gauge taken out and Changed for a different one but in the same housing, As for bigger injectors iv told i dont need them and Same for Map sensors But its already been map by angel on the old set up and is going into AMD for two days when i get it back sometime next week to be set up again seeing as they have the rolling road and offered the best price

and iv been told all that will make me 250 bhp and then in the summer if i still got the car i was looking at forged pistons and Nos kit just for some more fun
