Planned & Possible mods:

Planned Mods:

custom forged pistons
(20R design in a 22R bore size should give ~8.5:1 with 20R head for turbo)
aftermarket programmable fuel injection/ignition system (TEC, SDS, etc)
I've already ordered some components of the MegaSquirt DIY EFI system.
T3/T04 turbo system
extensive use of thermal-barrier & lubricating-film coatings
(such as Swain Technology or Techline Coatings)
Energy Suspension poly bushings for front suspension
larger front & rear sway bars (Koni or Addco)
Toysport, Cusco or custom-made front strut-tower brace
Kaminari body kit (or a clone like Erebuni or Mitcom)
spoiler for trunk lid (most likely from a Pontiac Fiero GT)

Possible Mods:
custom EFI lower intake manifold for 20R head
bore cylinders .060" over (total 2.5 liters, non-turbo only)
LC Engineering lightweight stroker crankshaft (total 2.6 liters, non-turbo only)
port 22R head (more), unshroud valves, match combustion chamber volumes
oversized valves (45.5mm Int/37.5mm Exh)
forged pistons (up to 10:1 for normally aspirated or ~8.5:1 for turbo)
forged connecting rods (stronger & lighter weight)
89+ 22RE intake plenum & throttle-body (major pain for 83-84 EFI tho)
Ground Control front coil-overs
Toysport or Ground Control camber plates
(or maybe eccentric bushings for front suspension arms)
