hi guys I would have this doubt on the processing of a 1.3 90hp mounted on a astra gtc.
the 90 hp uses a variable geometry turbine, the upgrade then, in theory, would be, or to increase my turbine ori., or adapt to another as, for example, that of the 1.6 mjet 120 hp... right?
the injectors and pump, you can always adopt those of the 120 hp?
I pose these questions to those who may have or have done on this engine to go beyond just the mapping.
surely the original clutch replaced with a reinforced( even why? gi? with a map thrust ? their reliable), and, especially, in maintaining reliability? of the engine without incurring a failure or another.
thanks a lot in advance.
