Engine Weight

The 7M-GE and 7M-GTE sections list the weight as 119.5kg (440lb), so is it 119.5kg/262.9lb or 200kg/440lb? 203.132.82.185 09:26, 23 January 2007 (UTC)[reply]

5M-GE Information

Knock Sensor was not included until the 1985 model. Wiki shows it was included with the 84 model which is untrue. —Preceding unsigned comment added by 97.113.2.237 (talk) 22:53, 13 April 2009 (UTC)[reply]

We are using calendar years, not model years. The article says 1984-1985.5 (the .5 meaning May), which corresponds to what an American (but no one else) would call the '85 model year. Stepho-wrs (talk) 00:01, 14 April 2009 (UTC)[reply]

3M torque output

The quoted specific torque for the 2000GT's 3M is 117 Nm/L, which would be extraordinary for a modern naturally aspirated high performance road car engine (for example the Ferrari 458 Italia's engine produces 120 Nm/L), let alone a 45 year old design.

Furthermore, that much torque at the quoted engine speed (4,800 RPM) would produce 117 kW, which exceeds the engine's quoted peak power, and is therefore clearly incorrect. 121.45.199.29 (talk) 10:39, 8 January 2010 (UTC)[reply]

Yep, that was wrong. I have corrected it to the advertised figure of 18.0 kgm (177Nm = 88Nm/L). Stepho (talk) 22:01, 8 January 2010 (UTC)[reply]
