Randomly someone walked up to my lastnight at a local car meet telling me they had some parts for sale... I walked away with a S14 LSD w/ complete housing for $70 and a Z32 MAF with pigtail for $60

I installed the LSD today and I love it! It's like having a real rear wheel drive car haha. Not sure what I'm gonna do with the MAF yet. What are the advantages of it? I don't really plan to make big horsepower anytime soon.
