FAST

Does your V8 need modern fuel injection, better airflow or an engine management system you can tune yourself? FAST stands for Fuel Air Spark Technology and makes fuel, air and ignition parts for American performance engines. Here you’ll find EFI systems, intake manifolds, throttle bodies, fuel injectors and ignition parts.

Fuel, air and spark from one supplier

FAST is an American brand that works with the three things a combustion engine lives on: fuel, air and spark. The brand is well known in the hot rod, muscle car and LS scenes, where many builders convert from a carburettor to electronic fuel injection or want more out of a modern V8. The idea is that the parts work together, so engine management, intake and injectors match each other and make it easier to get an engine that runs well.

FAST’s key products

EZ-EFI is a self-learning fuel injection system that replaces the carburettor and adjusts the mixture continuously, so the engine starts and runs smoothly without a long tuning process. For more advanced projects there is the XFI engine management system. FAST is also known for LSX and LSXR intake manifolds for GM LS engines, which improve airflow at higher revs. The range also includes throttle bodies, fuel injectors, fuel rails and ignition parts. See each product for engine fitment.

Frequently asked questions

Can I convert from a carburettor to EFI with FAST?

Yes, that is exactly what EZ-EFI is for. The system replaces the carburettor and learns the engine by itself. You will usually also need a fuel pump and return line suited to fuel injection.

What does an LSX intake manifold offer?

An LSX or LSXR manifold has larger runners and room for a bigger throttle body than many stock manifolds. It makes most sense on LS engines with a cam, cylinder heads or forced induction that can use more air.
