WRT to modding the K03S TIP: I wonder how much pressure that would able to accommodate...I simply bought a new TT/S3 TIP...I have everything for the setup and will install in the next two weeks...I decided to future-proof and purchased 630cc injectors + walbro inline + walbro intank to go along with new lines, turbo, OEM manifold (that was ceramic-coated), EBC, turbo outlet pipe, Forge Wastegate Actuator...A couple other tips and tricks will be added to this setup...
Good luck and keep us posted buddy...
