I'm fixing my fuel problem via a TEC II that I just bought. Rudy's right too, a in-line fuel pump with larger injectors will work too. Maybe a fuel pressure regulator on top of that. I'll probably do a fuel pump down the line.
In order to fit the Tib throttlebody you will have to get custom fabrication done to the flange of the Intake manifold.
Here's the math:
Aluminum welded around edge of flange
re-faced
new bolts tapped in
+ smooth out the welds to clean it up
