Kelford H182-SD CAMSHAFTS NISSAN RB20DE/DET & RB25DE/DET 278° & 272°/278°

This camshaft is another world first for Kelford Cams. 272/278 These RB cams feature the same 'split' intake lobe design that we have been using on Subaru cams for some years now.
"Split' lobes means one of the intake lobes has more duration than the other. This promotes swirl and superior combustion. The result is less total ignition requirenent, more boost capability and better performance.
The H182-SD specification suits RB25 head on RB30 bottom end. Street / strip applications with large single or twin turbo. 700++hp
