i ran a n/a 1.5 with a VNT17 for a couple years. i never had a problem with it. always ran like a top and had plenty enough fuel to blast 30+ psi out of that turbo. had stock n/a pump and 130 bar injectors. i dont think the engine really cares what injectors it has in it. only reason i swapped to 155's was cause i got a newer set with my turbo IP.
