Mitsubishi have a Turbocharged gdi engine, and im thinking about doing it to mine, the problems i see tho is the gdi injectors, the ecu and the gdi engines compression ratio. the gdi injectors i believe can only run up to 58psi without the car going into emergancy mode which obviously then brings me onto the ecu which would cause this....Does any one know if its possible to get larger injectors for the 1.8 GDI, i have a found a gdi turbo ecu by magnetti marreli which can drive the injectors and run the engine under quite large levels of boost, and lastley the compression ratio is somthing like 12.5 : 1 this would have to be lowered dramaticly, and restrict the car to run probly 7psi maximum boost.. the 4g93 turbo kit would do the trick up to obviously the injectors (aswell as fuel pump, pressure regualtor etc) so iwas wondering if anyone has attempted this or even looked into it.

I have not seem any GDI turbocharged. It is not a fact. the 4G92 and 4G93 (1.6 and 1.8) The 1.8 and 1.6 were turbocharged , but not GDI. reason is because GDI's have high compression than NA models and higher cylinder heat.

the lancer cedia is a gdi turbo?...
ive had a google search its only just came out on a few models

That sorry to say is headed thatw ay but , GDI's are high compression. The alternate engine of the turbo is a GDI, not the turbo. The turbo has sum characteristics with that of the GDI as in common rail but do not share the in port injection as a GDI. A GDI in this form was thought of but was deemed to be a waste as for the internal cylinder temps , and lower compression for turbo applications, thus the nozzle would have to be dramatically altered
