Came across what I think is a decent deal on a used Vortech model 1986-1993 Entry Level Mustang 5.0L V-3 SCi Standard (5-6 PSI) Complete System, Satin Part Number: 4FA218-010L Guy says it has about 20k miles on it. No end play or anything wrong with it. Head unit not serviced but he swears it runs fine. Says it was on his DD and only reason he pulled it off was to go to a bigger setup. He says it comes with everything but the air filter, air filter housing, and the pulley above the alternator. Now, the main thing that concerns me is the fact that he is in another state and it is a used supercharger. The guy could be telling the truth, but who knows. Once I buy it, it is my problem. The other issues are it has the cheapo plastic discharge tube, no bypass (doesn't come with the kit) and no inlet housing. ( Choices are either $150 for the stock Vortech air filter setup or $250 for a power pipe). If I go to the power pipe, I will need to get a blow through MAF and fenderwell filter. The other thing is he is not sure if the FMU has the 12:1 disk calibrated for 19lbers. Lastly the guy has zero feedback. What I would ideally want is a kit with a polished head unit, polished discharge, with a bypass, and a power pipe (or at least the Vortech air filter). I can polish up the head unit, but i'm looking at another 4-500 for the discharge tube, bypass, and power pipe. Plus no BTM or MSD with boost retard (again Vortech says not needed with this kit but I've always run one with a blown motor). Here is what he told me about the unit. So, what do you guys think. It's been over a decade since I bought a supercharger. If the price were about $1200 or so and then another $700 for the add ons I want- discharge, bypass, power pipe and MSD, its about $1900. It's a nice deal IMO until you start adding on the extras and items not included. I've seen complete S trims for $1500. If i knew the guy I would feel a lot better about the risk.
