ADJUSTABLE CAM GEARS . . . |
|
|
Adjustable cam gears are
the only way to change cam timing on a 20R or 22R series Toyota
motor and be accurate. Both single (Part# 19-1055) and
double (Part# 19-1052) adjustable camshaft gears are
available from LC Engineering.
Adjustable gears are generally used to correct camshaft timing after
the head has been milled or when the block is decked. Cam gears are
an effective way to “Dial In” a camshaft by advancing the cam for
low-end power or retarding the cam for top-end power. |

Adjustable cam gears can be used with mechanical fuel pumps by machining
the concentric fuel pump drive to clear the 3 separate 10mm bolts on the
adjustable cam gear. This is made easier by reversing the bolts in the cam
gear. Please call for specific information before attempting this. |
