I purchased a SEFI 13B to build up as a haul ***, things i thought of to make it fast include :

High flow injectors
Cold air intake
Stand alone fuel system
MSD ingition
alumium radiator and elec. fan
3mm apex seals
bridge port
2.5" dual exhaust
header
NOS (???)
Neon under body lighting (just kidding!)

And on the handling end of things :

Rack and pinion to replace an aging manual steering(thinking of using a Camry or Surpa rack)
new struts, shocks, and bushings
4 way disc brakes
15" tires and rims
new sway bar(s) and bushings
LSD

any ideas you may have that would have to help me pursue the goal of a fast car (10 sec. or better) would be greatly appreicated.

 

Many stand alone EFI's such as Haltech will not work with an MSD.

Port matched intake manifold, light weight flywheel

good luck
