Hi all. Anyone know how difficult this swap is? What is the general opinion of these auto transmissions? Do they really suck gas and power compared to the 4sp?

Also, was wondering if there was an accepted hierarchy of bolt on stuff that will increase the power in a 1.9 auto rig? Some of the things I was thinking about was header and freeflow
exhaust, MDS type ignition, KN filter stuff, does this stuff make a big difference? Any other tricks?

Thanks
Mark...
