R-33 Camshaft Selection

[Sil8ty]

I know this has been possibly covered a few times now.. BUT...

I am in the midst of putting together a turbo setup for my mates R-33 GTS-t Skyline.. Here is what i am doing..

- HKS 3037s Kit

- S/Steel Head Gasket 1.6mm

- 750cc Injectors

- SARD Adj Reg

- Power FC

- Vernier Cam gears

- Forged Pistons

Now i am stuck for what camshafts i should run.. Should i run the HKS 256 camshafts or go a bit bigger?? Or a combination of 256in / 264ex

The heads for now will remain std valvetrain.. Let me know your thoughts.. Goal is around the 350kW @ wheels or there abouts..
