If you had the choice of totally rebuilding our engines with forged units, ported heads, new everything basically... would you buy a used KL or KLZE? I can get a used KL for $200... thinking everything will be replaced with forged units and race port the heads with performance injectors... basically the works... will there be any gains in the end if I had used a KLZE and did the same thing? I'm thinking not... the computer is the question and when adding the turbo or sc it will be reprogrammed anyway. Am I right or Wrong?... What do you think Mike94pgt?
