Teehee, not only is this the diesel section, it's an old post.
Having said that, it's sad that I've made little progress since then, mostly due to finance, lack of facilities and general circumstance but also due to deteriorating health restricting my mobility. I feel I've got one last chance this year so the car's booked in for it's MOT soon and if it passes, I'll make the effort.
HG, diesels do have timing but it's regulated by the fuel injection point. Like a petrol engine, tuning usually involves adding timing though I'm not sure of the wisdom of doing so with nitrous. By the way, you might want to consider buying Trev's book, it's worth it's weight in platinum just for the facts alone.
From the information I've gathered over the years, I think the limiting factor will be clutch and traction as rapidblue mentions and being front wheel drive, perhaps very limiting. As a result Brett, I decided to save up and buy a minimax to get the most out of my kit. Plus I do have a contingency plan should the drivetrain prove totally inefficient.
Fuel quantity shouldn't be a concern as these cars are severly detuned and the injection pump returns far more fuel back to the tank than is fed to the injectors. Even if it were, I can swap pump parts from other larger pumps for more flow. Being a diesel, I also have the luxury of being able to use many alternative fuels such as propane and alcohol, not to mention the fact it can run on vegetable oil, heating oil, even engine oil
Talk about spoilt for choice.
Teddybare, I've said it many times and I'll say it again - diesel's are the future performance engines. They're decades behind petrol engines in R&D and if a heavy old pickup can do this...

Although this video wrongly claims sub 9 sec's it does look like a sub 10.
