262° cams to suit 3S-GTE engines with OEM turbo or upgraded turbo sizing 48-54mm in the 400hp range. Still suitable for street driven engines, maintains good drivability. Good increase in mid-range power compared to OEM cams on turbo applications. Great with E85. Kelford Cams recommend KVS109-3S valve spring upgrade. The intake camshaft has been machined to fit the OEM Gen4 intake trigger. These cams can be used in Gen3 engines but will require the supplied grub screw to be fitted to the rear of the intake cam.
