Just bought a 2008 Joyner Sand Spider, my family and myself very much enjoy it.
I have read quite a bit about the Weber carb upgrade and the turbo upgrade and would like to install one or the other, I can find information about the Weber carb and pricing for it but nothing on the turbo kit upgrade.
Could someone post a link or vendor information as to where I can read up on the turbo kits available for the Joyner SS 650???
I also have a 2008 and was debating the same thing about two months ago. I read every forum related to the carb and turbo kit here; called both Fast Freddies (Weber carb kit) and Unleashed Motorsports (Turbo). I ended up flying down to AZ to visit Unleashed where I met Scott (the owner) and test rode a 650SS with the turbo installed. I ended up purchasing the turbo kit from Scott at Unleashed Motorsports and installed it just before heading to Disneyland with the kids. I have not had any time to test it out yet other than a few runs up and down the street. You can contact Unleashed Motorsports here http://www.unleashedmotorsports.net Scott is also on this Forum every once in a while. They are great help on the phone for installation questions. I will be taking the buggy out over the next few weeks so if you want I can let you know what I found stock vs. turbo.
Install was fairly simple. They will provide you with a good installation instruction manual that provides the steps in order with pictures. Overall it took me about 6 hours to install but I did the oil return different than what the manual states (I pulled the CV to drop the oil pan and welded a nut on it). If you followed the instructions it would probably take about 4-5 hours. Unfortunatly I still have not had it out yet other than up and down the street; planning on taking it out this weekend though. I will let you know.
