I've always wanted a 60s-70s era muscle car or truck, but I think what I might do is drive the ranger as my DD for now and then eventually mod it out into a muscle truck (once money permits). I know its ranger and its not designed to go fast and I am well aware of the 302/351/4.6L swap options but I was thinking turbo or supercharging for a little more oomph. I decided on supercharger as the best option so I would keep my 4L (probably rebuild it in time) and just add this supercharger: http://www.explorerexpress.com/xcharger-0410-ranger-sohc-wtuner-projected-price-4700-p-768.html I just need to know a few things: 1- Is this kit legit? I have read a few good reviews, but more the merrier 2-Is this just a bolt on kit (I wont have to alter my engine, tranny, diff, cooling system too much to take the extra power and heat from the supercharger 3-any idea how much more power i can achieve just from this kit (I know specific figures are hard but any idea on the HP and torque figures? Again, I dont think an engine swap would be the best option, I wouldnt want a monthly project that's too complex and requires modding, a donor truck and a lot of time.
