90 vs pre 89 T's

[Michael J Myers <mimyers@prairie.NoDak.edu>]

I was just curious as to whether there would be a difference in hp 
between the single knock sensor 5 cyl turbo engines boosted to 1.9 bar 
and the dual knock sensor engine boosted to 1.9 bar.  I don't need exact 
numbers, just are they close.  Also, if an 89 came with an airbag, it 
also has the dual knock sensor?
