First of all, SR20 injectors will fit on a (and its GA16, not CA16). I believe most if not all nissan injectors will interchange.
The SR20 engine IMO and im sure others as well, is one of the best engines to work and modify. In all honesty, please dont contribute when it is apparent that you dont know jack about the GA16DE engine. Supercharger?? they dont make one for our engine. But this is not the issue please dont go
I just think we should get the I/H/E, crank pulley, JWT cams, JWT ECU (to optimize the cams), port and polish, the help of fluids like water wetter (it does work), then add the 240sx MAF, the bigger throttle body, and injectors.
One thing i was thinking about. A 2.25" exhaust system is optimal on the Sr20 engine which puts out about 120-125 HP at the crank stock. Now im thinking, if my GA16 is putting out those same numbers (theoretically), shouldnt I be able to gain some horsepower??
