Honda D16A6

I-4cyl 1.6L 16v SOHC

#

The original valve springs can handle a high valve lift, however they are very weak and cannot exceed the original rpm limit. For this reason, upgrading to Cat Cams springs is advised

#

if required, use extra shims to increase spring load

#

double spring PAC-D19864 can also be used on retainers 99351 and 99352(requires dedicated lower retainer and valve seal)

#

These camshafts do not have a fuel lobe. To use these camshafts in carburettor engines (like the D14A1), an electrical fuel pump should be used

#

FOR COMPETITION APPLICATIONS ONLY. Following details must be verified:

-

the camshafs must turn smooth in the cylinderhead, provide free travel by machining where needed

-

distance between valve seal and retainer at full lift must be 0.6mm at least

-

minimum valve spring travel of 1.0mm at full lift must be provided

-

distance between valve and piston 1.0mm (pref. 1.5mm). check 5-15° before TDC on exhaust, and after TDC on intake

#

ONLY for use in competition engines with independent engine management (throttle position sensor) or carburettors
