Can anybody tell me if you can turbo-charge a regular 2004 660? What dealers in the Worcester, MA area? Any idea of cost $$$?? What kind of increased performance can I expect? Has anyone else had this done and what has your experience been?

Thanks in advance.

Yes. Anything is possible. There is a bolt on kit from Sweden that brings up the HP to 85 without much modifications . Only problem is its $2400 US. Cheaper just to live with it or trade it in and spend the extra $2400 on the Turbo model (which is rated at 110 HP). Or better yet--save more money and buy a Z1 Jag when they come out with the trubo model in 2008 (rumored). A stock Z1 Jan runs 120 HP and $11,000. You should be able to find lightly used 2004 and 2005 Turbo T660s (STs or Trail or Touring models).

I chose to keep it as is since its a 2-up and I take family (read kids) on rides. Keeps me safe. For speed I have a 2007 F7 Firecat and a 1998 Thundercat. Both which can beat the T660 turbo on acceleration and top speed.
