There are no current forced induction kits available for the Altima SE-R There are rumors that some companies are working on a kit for the L31 chasis, but no confirmation that I have ever seen. A built from scratch custom kit is currently your only option. Speed Force Racing offered a kit at one point, but I don't think it is still available.
