There are bolt ons and then there is real tuning .

For a budget of $10k you could probably just be able to get a stage 1 supercharger kit

But to keep it atmo this is what I would do :


Chip tuned to specific cams
porting exhaust manifold and downpipe to cat connector
replacement of first muffler with resonator , removal of crimp section and replacement of suitcase muffler
CAI into stock airbox
Removal of throttle body heating
Haldex ecu upgrade
set of v3 KW coilovers

That should give you a fairly potent Bora that should beat even a chipped R32!
