Tomei PonCam Camshafts 258 duration 11.5mm lift – Nissan SR20DET (S14/S15)

Bring your Nissan S14 or S15’s SR20DET to life with these Tomei PonCam Camshafts (TA301B-NS08B). These cams feature a 258 duration lobe with hefty 11.5mm of lift. These are a direct drop in replacement cam for your stock OEM camshafts and can be used with OEM valve springs and retainers, you can even run these cams with no ECU modification (although we HIGHLY recommend tuning to take full advantage of the benefits these cams can offer your engine). These are some of the best drop in replacement cams on the market for increasing HP and TQ without the headache of swapping out springs and retainers.

For those looking to do a full cylinder head build be sure to contact us and speak to one of our tuners or engine builders about the best possible camshafts, valve train and head work aka port & polish for your engine build. Our engine builders are here to ensure you get the best combination of parts that will work together and get the most reliable power out of your engine build. We will need to know; What type of driving you do, What turbo/manifold will be used, what fuel and of course what budget?

The cams were maximized so that adjustable cam sprockets may not be required. The Poncams are only available in a 258 IN / 258 EX combo. If you are needing a longer duration or higher lift camshaft check out the Tomei ProCam options which can be purchased separately for intake and exhaust allowing you to create the combo that will work for you and the power band you’re after. If you have any questions be sure to contact us and speak with a tuner or engine builder!

TIP: Check out the blog for a detailed write up on the ultimate “dual guided shim” set up for your SR20. This is the best way to keep rocker arms and shims happy and in place at 9000+ RPM. This is hands down one of the best things you can do to your cylinder head unless you are planning to go the SR20VE head route.
