"The NSR stage 1 cam was designed to add power to your vehicle while maintaining the use of factory valve springs and pushrods. This cam was designed for ease of tuning and drivability, along with a smooth, factory type idle. As with all BTR offerings, you can be sure you're getting the utmost reliability as a result of thorough testing on our in house engine dyno and Spintron."
Cam Specs: 208/209 .492/.492 107+0
NSR cams are designed to be compatible with factory springs, however, you MUST ensure that the original springs are not worn and are capable of supplying adequate OEM spring pressures.
These cams use a 3-bolt timing gear pattern.
