1600SX?
Dont want to be a killjoy on this one but I wouldnt start with a 1600sx! You will need to uprate almost everything from suspension, brakes, exhaust, gearbox etc etc.
The conversion on the turbo alone is going to cost £2,500 and I would then add at least another £2k for everything else. Is £4,500 worth spending on a 5 year old 1600sx Bravo? I would have thought selling the 1600 and buying a HGT would probably keep some of the cost down as the suspension, brakes, 'box etc etc are already some way to what would be required.
I am not having a pop at 1600SX' before anyone leaps at me just questioning the starting point.
Cheers
