* Type A
Designed to best suit the stock & N1 turbos for optimum performance balance of low to mid range torque.
The Exhaust cams duration was reduced to maintain best idling.
* Type B
By extending the duration timing compared to the Type A Poncams, both response and peak power was raised and these camshafts best compliment the mid to large size turbo charged applications.

* TYPE R(for Stock Cat. Equiped Cars)?
The Type R camshafts were designed due to popular demand from end users who are looking at upgrading the performance potential of their GTR while staying within the limits of recent street legal requirements. Recent laws on emissions and exhaust noise was made stricter in Japan so to have a quieter car by running smaller exhaust systems raises the exhaust back pressure which greatly reduces the response and hinder performance. Our engineers then designed these Type R camshafts to suit the needs of those who need to keep such setup and benefit with performance gains.
| KEY DESIGN CONCEPTS |
| * |
To improve performance gains on cars running catalytic converters |
| * |
To maximise the stock turbos performance potential. |
| * |
To reduce the exhaust back pressure |
| ? |
Improves overall throttle response and torque |
| ? |
To protect the stock turbos performance limits and minimise turbo failure. |

| TYPE A |
405 ps |
| TYPE B |
406.33 ps |
| TYPE R |

The peak power output is less than the Type A & Type B camshafts but the response is better with the Type R camshafts. |
