JMP / JPM ? has a TWIN kit and new revised single kit (it is now in the engine bay not under mounted) for a good entry price as well. Nothing to be skeptical about, this kit is developed by SSMS and tuned in conjunction with MPT. Both reliable and reputable companies. What is scary to most people is they are unsure of the "plug and play" nature of TURBO kits available to us in the 3.7L crowd. Pro Charger is such a well known name, been doing it forever, promises true plug and play (which its not), and so its easy to swallow, but I tell you its lot more expensive than the turbo route (from what I have seen with others build costs). Honestly, I was saving for the Pro Charger, I was going to replicate the D1SC build here in this thread, but for 2k it was too hard to pass up. I am not even able to install this on the Stang for another year. I am going to be overseas still, BUT I am preparing.Wow! I missed out on that deal. You got a great deal. Hope it all works out for you. I am still a little skeptical on the twin SSMS turbos kit as this might be the only one out there. Good luck to you. My goal will be for the 400 hp numbers too! What ever route I choose in the future.
