If you are convinced that the standard factory Evoluzione (Sep '91 and beyond) isn't good enough....What can be done ?
- Phase 1 : Airfilter, chip change for i.e. higher boost settings of those of standard turbo, quickshift for gearbox, removal of mid-exhaust-box;(245-265 Bhp)
- Phase 2 : hybrid-turbo or exhaust manifold for better cylinder filling, headgasket (steal rings) in situations of turbo swap, other fuel-injectors or different fuel pressure pump, chip (again); (up to 300/310 Bhp);
