TUNING SERVICE

This tuning service is available at Tomei HQ. The cylinder head must be sent in for the upgrade.

The cylinder head is baked up to 200 degrees celcius, which then allows the guides to be installed easily.

The valve guides are then frozen in Liquid Nitrogen to – 200 degrees celcius for an easier and safer installation. When the cylinder head cools down & the valve guides warm up, they will then bed well together, giving the sealing required.
