forged pistons went away in 93. 89 suspensions aren't as good, but 89-92 have the same motor. 88CA cars are also the same.meangreen92 said:The '89 is the first 49 state Mass Air car. It also has forged pistons. Ford quit using the forgings sometime around/during the '92 model year. '89s also don't have airbags, which are something many of us would rather not have anyway.
I would worry about a bunch of crap other than air (i.e. water, debris) being rammed into the air filter. I guess it depends where your ram air intake is located. I would probably only run the under-the-front-bumper ram air system on the track. (This is opinion).
I've got a "fenderwell" cold air kit on mine, and it works real well. The filter doesn't seem to get fouled/dirty at all. I noticed a power increase right away. Although, the dirtier the existing air filter, the more drastic the power increase.
