I wouldnt say they where the best Hiflow turbo out Toytuning and fensport hiflow turbos are one of the best! The tongs hiflow only has a larger compressor wheel everything elss is just the same as a stock ct9 With the toytuning and fensport ct9's you get a larger compressor wheel cutback exhaust turbin wheel 360degree thrust bearing etc But even so its a good find and still worth around the £350 mark
