I know this is not the usual vehicle that is modified on toymods, but can anyone help with this. I have just completed an engine and gearbox mod on my YH71 HiAce ,the engine is a 4.1 ltr falcon with 3 spd auto. The problem is the toyota diff ratio is to low at 4.3:1, that converts to 28kph per 1000rpm. Does anyone know of a higher ratio gearset that will fit this diff or of a diff that will fit the HiAce. This is a low budget conversion ,so far the conversion has cost about $500 . I had thought of cutting down the falcon diff ,2.77:1 lsd & disc brakes, but I got a quote for shortening and resplining the axles of $110 each axle. The budget can't make it. Thanks for any help.
