what's the difference between a 240Z and 260Z?

Question

Accepted Answer

Great question — the 240Z and 260Z are siblings in the iconic S30 Z-car family, but there are some meaningful differences:

## The Big Picture: Engine & Power

**240Z (1969–1973):**
- 2.4L inline-6 (L24) with ~150 hp
- Carbureted, simple and reliable
- 0-60 in about 8 seconds, top speed ~125 mph

**260Z (1974, US market):**
- 2.6L inline-6 (L26) — stroke increased from 73.7mm to 79mm
- **Early 1974 US models:** Only 140 hp (emissions choked power despite more displacement!)
- **Late 1974 (74.5) US models:** 165 hp (properly tuned at last)

So yes, the extra 200cc brought more torque, but US emissions regulations actually made early 260Zs *slower* than 240Zs. The "74.5" cars restored proper power.

## What's New on the 260Z

Nissan added a few extras to keep things fresh:
- **2+2 variant** — longer wheelbase with (cramped) rear seats
- **Automatic option** — 3-speed auto for non-purists
- **Stronger chassis** — thicker frame rails and firewall for better rigidity
- **Bigger bumpers** — US-mandated 5 mph bumpers
- **Updated interior** — better climate control layout

## The Collectibility Factor

Here's the kicker: **260Zs are rare**. While Datsun sold over 160,000 240Zs in the US across 4+ years, the 260Z only lasted for the 1974 model year (plus that mid-year "74.5" refresh). Many enthusiasts actually prefer the 260Z for builds since the stiffer chassis handles more power better.

The 260Z you're looking at is a cool find — original, burgundy, and with that classic air-cooled inline-six rumble. What's drawing you to this era of Z-car?
