Lamspeed Racing C630 Nickel Bronze Valve Seats - Mitsubishi Evo 1-9 4G63
Details:
Valve seat requirements may change depending on the application the engine is used for. For most, the OEM seats are fine. For the serious racers with over 1000hp whether it be for drag racing, circuit racing or just a street car with ridiculous power.
From our research and development with our own engines and many race teams, we have come to the conclusion that a valve seat must do the following:
- It must cool the valve
- Support and seal the valve when it closes
- And most importantly act as a shock dampener to help cushion the valve when it closes at high RPM.
This is where we have come to design our own C630 nickel bronze valve seats to accomplish the above.
These are to suit the 4G63 cylinder head from the Mitsubishi Evolution 1-9. These need to be fitted and machined by a competent machinist.
