Newbie could use some help on (sort of) an SD20 swap - removing AC and power steering

OK, not really a Datsun, but I have 510 friends and after reading content on this site I am thinking I found the right group of inspired people to provide some coaching.

 

Basically I am putting a Silvia S14 SR20DE into this car (1967 Triumph TR4a) and will face a number of the same issue many of you have when doing a similar swap into a Roadster or 510. Quick back story;

This is my 1967 Triumph TR4a  that sat unloved in Seal Beach in Orange County for 22 years before I pulled it out of a garage.. The darn thing just ate it's under 100 mile professionally rebuilt engine and I am more than slightly fed up with it. It is going to run me around $4,000 to get it rebuilt AGAIN and I realized that for not wildly different money I could install a SR20-family engine and have a better, more modern, better support engine attached to a proper 5 speed that would be both more powerful and lighter. As you can tell from the picture she is a driver, and my intention is to use her for long distance touring events in/around SoCal.

 

OK - so back to the question at hand. My SR20DE has A/C and power steering drives that I don't need and rather than inviting a solution to removing those I seems like people here will have solved that issue far better than I would. Is there a go-to solution on removing those bits and simplifying the belt set up for just the water pump and alternator?

 

Thanks in advance for the help!

First, thank you for the response. Very helpful and much appreciated.

 

So it looks like I can leave the water pump and alternator as connected and just remove the power steering and AC belt / ancillaries then. Other than appearance / being tidy is there any reason to swap out the pulley for a single row?
