I've got a 93 1.3 aav spi genesis which is currently fitted with a 1.8 golf throttle body (with the 1.3 injector)and GT cam. Its a nippy thing and is better than standard, but I used to have a 1990 1.3 NZ engine with the MPI setup on it, and even in standard form I seem to recall the NZ feeling pokier. Reading about, the MPI setup off a NZ coupled with a GT cam seems to provide good results, but woult there be any benefit over my current setup? I kept the NZ engine with all its MPI setup, coil, ecu, and ecu loom and intended to swap the inlet manifold etc across. Looking at the loo
There are three types of multipoint injection engine, the G40 is quite easy to spot. This guide is to help you spot a NZ from a GT This is a GT engine (some light modding) This is a NZ engine The NZ is a multipoint version of the AAV engine which was later developed into the GT (3F). • The NZ has the same camshaft as the AAV and was meant to produce the same 55BHP but because of the improved air and fuelling some NZ produce 60+ • The NZ throttle body has a throttle open sensor not a position sensor like the GT • The NZ has the same gearbox as the AAV • The NZ has
abd engine that previously ran fine on carb fitted all 3f mpi bits except the cam starts from cold and sounds normal , quickly starts to sound rough with a unhappy idle , with the blue sender undone it runs worse ive attempted to set up the timing but unsure if the rough idle effects it..above idle it sounds better and drives semi okay when hot it will not restart - after one hour it starts again tried 2x temp senders , new coil , ecu and (correct)dizzy works on my mates gt ,car has no o2 sensor at present, fuel pumps are running when it refuse
