    Hi. How much boost this valves can handle??
    • 0 of 1 people found the following answer helpful

      A:  The valve springs and retainers are not related by how much "boost" they can handle. If it helps this kit is capable of 9500+ RPMS

  • Q: High rev  Robbo127895 years ago

    I'm currently in the process of designing a very high revving boxer. I have yet to be able to find a valve train set-up capable of handling a 12k redline. I will be running a very destroked ej257 block and I'm curious as to whether or not these would be capable of handling that or if you had or know of anything that can
    • 0 of 0 people found the following answer helpful

      A:  We would need more information on the head setup to give you an answer to this question. Given the desired 12k RPM limit we would need to know the acceleration and jerk of the lobe profile that you select. The weight of the valves you will be using along with the thickness of the valve tappet and boost pressure.

  • Q: Shim and bucket  Sasuke836 years ago

    Does those retainers cope with shim under the bucket? I don't see any bore for that on top of the retainer. I am afraid of falling.
    • 1 of 1 people found the following answer helpful

      A:  These are designed to work with factory buckets on the vehicles listed in the confirmed application listing. We have never seen issues with the buckets spitting out the factory shims when used with these springs on the applications that they are intended for.

      A:  these nor our 5743 kit is designed to use the Subaru shim-under bucket style, only the Subaru shimless style bucket. We will be releasing the shim-under bucket design in early April for both our Subaru EJ spring kits.
