Engine Upgrades for Your Vehicle

Mapping - remapping via aftermarket ECUs and piggyback ECUs are great upgrades on the B series.

Fast road cams are one of the most significant mechanical upgrades, but they must be fitted by someone who knows what they're doing, and they're not always easy to come by. However, you might be able to find a local outfit to regrind a standard camshaft.

Note that many of these mods will NOT ADD POWER ON THEIR OWN in most circumstances, although they can aid boost power after other mods by removing the restriction.

Turbocharger and supercharger upgrades - forced induction is the most efficient way to increase air supply, allowing you to burn more fuel and produce more power. It is one of the most expensive modifications, but it delivers the best results.

Porting and flowing the head's goals are to get air flowing into the engine while removing flow limitations and turbulence.

Intake manifolds, Sports exhaust header/manifold, Fast road camshaft, Panel air filters, Remaps are common stage 1 changes.

Stage 2 modifications commonly include: a sports catalyst and performance exhaust, a ported and polished head, fuel pump enhancements, a fast road cam, and high flow fuel injectors.

Engine balancing and blueprinting, adding or upgrading forced induction (turbo/supercharger), competition cam, internal engine modifications (pistons/head/valves), dual charging conversions are common stage 3 changes.
B series turbo upgrades and turbo conversion kits add substantial power to your project.
