Swap Info Needed

[A94Civic]

My friend has a 91 mighty and we are looking to do the 4G6 turbo swap in it. He has the 4cyc 2-wheel drive fuel injected motor with a manual trans. What all do I need for his swap? I know motor. What about the ecu? what does 6 bolt and 7 bolt mean and how do I find out? any info would be great and as well as the best place to find all these parts would be awesome. Thank you folks and hope to hear from you shortly.
