Things I would do:
Oil cooler
Lighter 15x7" wheels - you can remove 20kg of rotating mass easily
Change PAS fluid, coolant and gearbox oil for new
Do your brake ducting
Otherwise dash might only be an issue due to airbag missing and light on.
Oh and...
check engine timing (remember pulley can slip)
check plugs are tight and good
bypass the inertia switch
change fuel filter if fitted
check you are getting full throttle (seen so many that don't)
