I have seen the Whipples around still listed on the net, but no Jackson kits. They all say 2000-2002, though. So not sure why they say they won't work, not like that would stop me from trying though.
I was thinking about one, but am OK for now as I have stick shift, and I want to keep my lifetime powertrain warranty. Not sure it'd be a good idea anyways, though. There's enough torquesteer as is now. I think it'd torque steer like crazy with FI.
