FLI has seen many power systems over the 20+ years of business. We not only have seen these power systems but we created, tested and provided an end product to the customer after we custom map the controls on our chassis dyno. Online calculators are great for a start but there are MANY factors that have been overlooked which cannot be adjusted without the end result or experience. Each part of the power system we create goes through our own in house evolution of efficiency. Meaning, if we come across a better part or combination of parts for a better outcome, we change them. As technology increases product availability, FLI usually raises our standards. The end goal is to provide the best product for the customers needs.

FLI does not build our engines in house anymore. We understand the importance of being an expert and we do not have the time or space to be an expert in engine building. However, FLI has partnered with a few experts around the world who does hold this class on specific platforms. FLI ALWAYS chooses the parts, build quality and port sizing via flow data which is why we call it an FLI Spec product. An FLI Flagship product is the best of the best we came up with. You cannot get these products anywhere but from FLI.

We carefully choose the parts and labor combination on our Long Blocks to ensure a high level of Volumetric Efficiency to match the power package, fuel, ignition and electronics package.

Contact FLI for a COMPLETE POWER PACKAGE BUILD including wiring harnesses, fuel, ignition, exhaust and power systems.

This Nissan SR20VET Flagship long block offers high level of engineering specifically for either force induction applications. Response and high flow at higher RPM’s are key to these engines.

Prices are subject to change given the world we live in now.
