30 HP Difference between 84/85 n 85.5/86

[2.3T Fan]

I want to know why there is a 30 HP difference between the
84/85 n 85.5/86 SVOs.. What changed besides the Exhaust??

Im lookin at a 85 SVO n I jus wanted to know y the HP is 30
Less (84/85 = 175 but 85.5/86 = 205).. STOCK SVOs r set at
15 PSI right?? When did the SVOs get the Firm Ride Control??

Thank You,

They also changed to a larger air meter, slightly larger cam, and a more aggressive timing map in the ECU. All of these helped to increase hp.

I'm not aware of any SVO's have ride control, only 87-88 TC's. All SVO's have adjustable Koni shocks/struts though.

The 85.5/86s got the smaller .48 turbo housing to make it spool quicker and a different cam for more top end.
