KTCos,

Yes, Light Blues are the next step up from 803's (dark greens).........The light blues are also known as Motorsport 400's......very good spray pattern, and these Light Blues are often overlooked (peeps prefer to go for greys instead)......They are good for 400 BHP + a bit more with the corected fuel pressure.

Ask IMA (Phil) about cost, but dont forget you will need a chip to suit, and a good rolling road or live map session to get the set-up spot on!

On 26 LBS/PSI of boost my old Saph 4x4 with the Paul Bailey built engine made 406 BHP/396 ft/lbs torque on Interprpo rollers........I would say that the light blues are a perfect match for the T34B turbo..........But the correct set up - especially fueling is absolutelly essential
