I am not sure where to look on the web, but I know that the new Roush V6's have an option for a Vortech with a 6 or 9 # system. Probably an A-trim. Kenny Belle makes a Possitive Displacement system, which is really fun for around town fun!! But it is only a 6# system, good for roughly 75-100 hp.(very overrated)Check them out at
www.kennybelle.com
I have heard of people using an S-trim, but not sure of the validity. Look for them at
www.vortechengineering.com .
Not sure if that is the right address or not. Just do a search on google or something. Good luck!
