In '94, yes the went to the 1.8 engine, bigger brakes blah, blah,blah. '94-'95 had the 1.8 but are still OBDI, '96-on are OBDII. The 1.8's offer a little more torque, but don't rev as high as the 1.6's. All a matter of personal preference, the aftermarket is huge for both. I love mine, flat-out the funnest car I've ever owned. Not the fastest by a long shot... But the smile per mile quotient can't be beat.

On a side note, if you buy one... Get a real roll-bar by Hard-Dog or BullFrog or whoever, just not a "style-bar" from e-Bay. Style-bar's are called a mousetrap for a reason, in a roll-over they collapse and pin your head down somewhere around your crotch.
