Ba Falcon 3V V8 Converting To Xr6 Turbo Engine Please Help

[genuine honest person]

2 years ago I bought a v3 v8 xt one tonne ute with 47000 klm on the clock .bought it to fit a supercharger to it ,but not long after owning it found out engine was stuffed.so after lots of reading decided to go for a turbo instead .I have just bought a ba xr 6 turbo wreck with 108000 klm on the clock ,about 12 month 35000 klm ago elite have done some work to it .nizpro cooler,nizpro air box nizpro valve springs.walbro 500 fuel pump bigger injectors .plus a tune .it makes 327 rwkw and 760 nm it ran a 12.355 at willowbank .it has a 4 speed box .now I have a lot of work ahead of me to fit all this to my ute can anyone tell me what I got to look out for thanks .I have got a 3.9 ratio diff with a true track locker what size stall to suit this set up ?peak torke is at 2700 rpm so a 2600 rpm -2700 rpm stall would be best ?
