HP Engine Kits Power You Up!
Because each motor and HP Engine Kit is different, we can't give you an exact HP figure. However, for N/A engines we usually see an increase of about 40 HP (min.) depending on bores and compressions chosen, and for turbo's & superchargers the total power will be in the boost. (By adding cams, headers, pulleys, exhaust systems, air intakes, etc. the amount of HP will significantly increase as the total HP is the sum of ALL the performance parts added to the motor)

Bolt-On Products w/HP Engine Kits vs. OEM Engine Parts:
Add-ons (such as cams, headers, pulleys, air intakes, etc), are sometimes fast and cheap to install, but in most cases will not meet expectations for increased HP. Typically the reason for this is that OEM compressions and bores do not supplement them. Add-ons love higher compressions and bores in N/A engines which is exactly what our HP Engine Kits give them.
