I suspect that it should fit right on but I know the drive shafts are thinner than the 1.3 or 1.4 but if you changing the sun gears in the diff to have the fatter drive shaft. The only other thing that may not fit is the gearbox input shaft but I suspect that they would be the same size
It's OBD 1 you can get adapters to the new OBD 2 but if you are going to tune the car then the best thing you can do is put a programmeable ECU in so you are free to mess with it and should be the standerd OBD 2
I know you can get some nice high lift cams but I was wondering if the 1.6 cam's from the almera would fit the micra engine. I have also been wondering about the mgf manifold as it's alot cheaper than anything that's designed for the k11 micras. Any help is appreciated thanks
