Sorry to post another thread about this topic but I am struggling to find the answer to this question. I am currently swapping a 1.3 into my pre face k11 that has a NATS ecu with the red chip if I remember correctly. The breaker I got the engine from said that I might have to swap the 1.0 fuel rail or to the 1.3 to get it to run. The 1.3 is in the car now and cranks over but doesn't fire. The battery was flat however when jump starting it failed to fire still. Has anyone heard of having to swap the fuel rail in the conversion before?
