This one was an auto ..
It was also setup so that it had the "armed" switch, but the magical nos button was under the accelerator, so that when it was armed, it came on only under full throttle..
And diesel engines are usually built quite strong, so apparently quite good for use with nos..
Another car show "top gear" (I think it is on in aus) had a nos article as well.. a £500 jag racing a bunch of exotics (including a ferrari).. add a massive nos kit and it caned the lot of them!
