Engine Swap Checker: Which LA Code Do I Need?

Planning an engine swap, turbo or engine modification? Enter the factory and new engine details to see which LA code applies, whether you’re within the 20% power rule, and whether the engine size suits the car.

The vehicle

What you’re doing

Heaviest sedan version with the biggest factory engine, no options. Used for the capacity limit on passenger cars.

Most powerful factory engine for this model

New or modified engine

Rotary? Enter the total capacity (a 13B is 1,308 cc) and set “Rotary engine?” to Yes. It’s doubled automatically, as Table LA1 requires.

Guide only, based on VSB14 Section LA (codes LA1 to LA4, Table LA1). Emissions (LT3) and noise (LT4) testing may also be needed, and brakes may need upgrading if power goes beyond the factory options.
