Hello all, Im new to the forum and I have a few questions. I have a 91 legacy motor that I am currently working on putting in a street legal dune buggy (sand rail). From what i understand the motor has about 130HP stock. I would like to boost that amount up quite a bit. What are the most cost effective ways to gain the most HP for the money? What would you guys reccomend I do first? thanks.
