Nissan Factory Camshaft Specifications

The link below will take you to my list of Nissan OEM camshaft specifications. I decided to publish something regarding them for education purposes only after doing some research on the different camshaft duration and lift as a comparison to aftermarket configurations. There’s a cloud of misconception regarding FWD and RWD SR20 camshafts. With the exception of the SR20VE camshafts, the camshafts are interchangeable.

  1. P11 Primera SR20DE

In 240/9.4mm

Ex 232/8.5mm

  1. P11 Primera SR20VE

In 220/8.4mm > 264/10.7mm

Ex 244/6.6mm > 268/10.34mm

  1. P12 Primera SR20VE

In 228/10.10mm > 278/12.0mm

Ex 244/8.4mm > 280/11.15mm

  1. RNN14 Pulsar GTiR SR20DET

In 248/10.0mm

Ex 248/10.0mm

  1. B13 Sentra SE/SE-R SR20DE1 990-1994

In 248/10.0mm

Ex 246/10.0mm

  1. B14 Sentra SE/200SX SE-R SR20DE 1995-1999

In 248/10.0mm

Ex 246/10.0mm

  1. S13 Silvia/180SX SR20DET

In 240/9.2mm

Ex 240/9.2mm

  1. S14 Silvia SR20DET

In 248/10.0mm; 240/9.2mm

Ex 240/9.2mm

  1. S15 Silvia SR20DET

In 248/10.0mm; 240/9.2mm

Ex 240/9.2mm

A pretty neat factoid exists regarding the FWD P10 Primera and B13/B14 Sentra SE-R/200SX SE-R  intake camshaft with its 248 lobe and 10.0mm lift. The PS13 Silvia/RPS13 180SX series uses a 240 lobe and 9.2mm lift. You can use the P10/B13 intake camshaft in the RWD PS13/RPS13 for a mild bump up profile over stock without any modifications needed. The RWD SR20DE exhaust camshaft has a 246 duration and 9.2mm lift compared to the DET’s 240 duration and 9.2mm lift. If you’re on a budget or do not want to go with aftermarket camshafts, then this is the way to go.

I’m still researching the little-talked-about SR20DE Roller Rocker series engine and other offshoots of the SR family, and I will update this page as I find more information.

The link below expands into Nissan other Nissan products like the Skyline series and 300ZX/350Z.
