Features & Product Details

High quality designed springs are required to transfer the exact movement of the camshaft to the valves at high engine speeds on high performance engines. The TOMEI products are always engineered with precision in mind to suit the user’s needs. So with this in mind careful choices in material selection have been made with surface coating and other technologies. Then the pre-production products are put through an extensive testing program for checking durability, quality and performance. They spend time and money to help you save your valuable time and money.

By combining several steps of spring rates into the one spring the vibration frequency becomes amazingly high. This greatly minimizes resonance and the chances of surging.

Oil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and they evolved it even further. Combined with a new optimized design, not only did they make it tougher, they also succeeded in suppressing valve jumps or bounce even when raising the engines speeds RPM limit.

QUESTIONS & ANSWERS

  • Q: high rpm  Chubaru242 years ago

    I'm doing an engine build on an Ej20, and looking to go for a high rpm build. Are these equivalent to the cosworth high rpm springs or would I get more from the cosworth's?
    • 0 of 0 people found the following answer helpful

      A:  With stock retainers, you would be able to rev these to 8K RPM. If you do a complete head build, you could rev these over 9k as long as the rest of the power train can hold up to it.

  • Q: 8k safe ? Stock retainer   Corysti6 years ago

    Dose that mean the stock retainers should be able to hold them down to a 8k rev? Thanks for the help
  • Q: Retainers?  05FXT04STi6 years ago

    Since these don't include upgraded retainers, is it possibly to use OEM retainers and still be able to rev the motor (ej257) to 8k safely?
    • 0 of 0 people found the following answer helpful

      A:  Yes these would be able to be used with stock retainers or any other aftermarket retainers as long as they are OEM dimensions. Rev wise, these should be able to keep up with no problem to 8K, just make sure the rest of your powertrain can.
