Competition cams are engineered to provide maximum power at the high end of the RPM range, which most everyday commutes do not allow!ĭifferent EA390 engines react better than others to less aggressive cam durations. When driving in heavy traffic, a Race camshaft will never be a joy to live with since the bottom end power will be highly lumpy. On a regularly driven automobile, strive to adapt your power band to your normal driving style. Cams with durations ranging from 264 to 272 seem to be the most popular options on this block. Motorsport camshafts boost the higher rpm power range, but the vehicle does not idle smoothly and low end power almost always suffers as a consequence. Changing the cam profile on an engine changes the intake and exhaust durations, which may have a significant impact on torque and power production.įast road camshafts often boost torque across the rev range you may lose some low-end power, but your higher-rpm power will be greater.ĭespite having a V layout engine, the EA390 utilised a DOHC design due to the near closeness of the cylinders in each bank. Just because a component is popular among EA390 owners doesn't imply it's worth having, therefore we'll concentrate our attention and tuning suggestions on the parts and upgrades that will offer your EA390 the most value for money in terms of power gain.Ĭam improvements may result in significant increases.

PORTING KIT USNG MODS MODS
Typical stage 3 mods often include: Internal engine upgrades (head flowing porting/bigger valves), Adding or Upgrading forced induction (turbo/supercharger), Crank and Piston upgrades to alter compression, Engine balancing & blueprinting, Twin charging conversions, Competition cam. Typical stage 2 mods often include: high flow fuel injectors, Sports catalyst & performance exhaust, fuel pump upgrades, Fast road cam, Ported and polished head, induction kit. Typical stage 1 mods often include: Fast road camshaft, Intake manifolds, Panel air filters, Remaps/piggy back ECU, drilled & smoothed airbox, Sports exhaust header/manifold. Porting and flowing the head's aims are to get air flowing into the engine while reducing flow limitations and turbulence.It is one of the most expensive modifications, but it delivers the finest results. Upgrades to turbochargers and superchargers – forced induction is the most efficient way to increase air supply, enabling you to burn more gasoline while producing more power.Intake and Exhaust - Keep in mind that these changes will NOT ADD POWER ON THEIR OWN in most circumstances, but they may aid boost power after other mods by eliminating the limitation.However, you may be able to find a local outfit to regrind a standard camshaft. Fast road cams are one of the most important mechanical adjustments, but they must be fitted by someone who knows what they're doing, and they're not always easy to locate.Mapping - remapping offers the largest cost reductions, however aftermarket ECUs and piggyback ECUs are also options.Be sure to subscribe and support our new channel.īest Engine Modifications for Your 3.6 VR6 Please watch our video which covers the 5 principles of tuning your car.
