The length isn't a problem. The car is 173.4 inches (440.4 cm) long. My NSX is in a space that is 176 inches long.
The width of the car is 71.3 inches (181.1 cm); the widest point is at the side-view mirrors (EDIT - No it's not - see below). That leaves 63.9 cm on both sides of the car for entering and exiting. Whether that's enough depends on whether you need room on both sides of the car. If you have a passenger, he/she can exit the car before you pull into the garage, which enables you to move the car closer to the wall on the passenger side, thereby leaving more room from the wall on the driver side.
To illustrate this: If you could maneuver the car so that the passenger side-view mirror is just touching the wall, that means all 63.9 cm (25.2 inches) would be the distance between the side-view mirror and the wall on the driver's side. If the car were perfectly centered, that means only 32 cm (12.6 inches) between the side-view mirror and the wall on each side of the car.
I park my LHD NSX in the leftmost space of a three-car garage. I generally park it fairly close to the wall on the driver's side. It leaves just barely enough room for my moderately large body (5'9", 205 pounds) to enter and exit the car; it's a tight squeeze (requiring occasional minor gymnastics) and I wouldn't want to have to park it any closer. I measured the distance between my driver side-view mirror and the wall, and it's 20.5 inches (52.1 cm).
If you can park your car within 4.7 inches of the passenger side wall, you will have the same 20.5 inch clearance on the driver's side as I have. Your ability to do this may depend on any obstacles you may have protruding from that wall, as well as on the approach to that wall (i.e. the door frame for the garage door).
EDIT: After writing the above post, I double-checked the diagram on page 3-17 of the 1991 service manual, and it's clear that the width measurement does NOT include the side view mirrors. The side view mirrors protrude about 4 inches from the body panel below, and that is where the width measurement is made.
The distance from the car to the wall of my garage, measured from the body panel to the wall, is thus 24.5 inches, not 20.5 inches. That means that you would only have a chance of entering/exiting the car comfortably if you could park it within an inch of the passenger side wall.
