HKS GT2835 PRO S KIT or HKS GT3037 PRO S KIT!
hks 2835pros - full boost under 3300rpm - 350hp @ 16psi.....
what more could you want? more power? then add some boost, and some cams and aim for around the 400hp figure with 18-20psi
BUT if you want more power go the 3037 pro s kit, seems pointless if u ask me .... i find 350 more than enough good enough to run a mid 12 or lower if u know wat ur doing behide the wheel
ohh and as for fuel eco, 400/450km out of the tank even running full boost every day...
