What are the turbo specs? It's hard to give an opinion with only 20% of the info. There's a lot more to a turbo than the inducer size.

The 69 will make approx 600whp on 15psi. At least those "GT45's" have good sized turbine wheels. Id go with the cheaper 69. Id guess it will make enough to push the limits of the shortblock.

Go with the 80mm otherwise youll run out of steam before 6000 rpm

Stock bottom end - do you want to bend a rod or fail a bearing?

One is going to make you more torque limited one more power limited

@A-Low...thanks for the response. I would be interested in your results as well as I am currently in a long and slow drawn out 5.3 turbo build myself but have not chosen a cam or turbo. Have very similar specs as yours in front of a T56 and looking for a similar power goal. Have been eye balling the GT45 76mm and 80mm as well as the BW S472.

80 just sounds cooler
