s13/s14 cams

can i run s13 cams in a s14 ? and what are the differences

The s13 intake cam is slightly more agressive, i am pretty sure S13 cam’s will work in S14’s

The exhaust is the same and will work 100% the intake should work fine as well

what do you mean its more aggressive

it means its better.

now buy my cams!!!

Aggressive as in the duration being longer (more time for air to enter the cylinder) and valve moving dropping down a little farther (again allows more air to enter the cylinder).

The S14 Blacktop has a Advertised Duration of 248°/248° for intake/exhaust. The S13 Redtop has a Advertised Duration of 256°/248° for intake/exhaust. The duration will be slightly longer and thus allows more air in and should result in a slight power increase (dont expect 20 hp from it…)
