Have you thought of N/O2 kit instead, okay so you'll have to keep having the bottle refilled every now and then or everyday if you go mad with it ?

Just a thought ?.
Don't forget even with specialist insurance companies, if it's a one-off conversion that hasn't been done before the premuim could be high for the the trouble you've gone to ?!. Maybe an idea before you go and actually do a conversion, to get a quote before you get your spanners out !. Otherwise chap you maybe spending half your budget paying someone else for the prevellage of "your" fun.
Not trying to put you off the project, just thought I'd point out another angle of the project !.
We've all been there, tolled away at a project, only to have the insurance companies P155 on our chips !!.
Good luck with your project though.
P.S. there is somewhere on youtube (or used to be) a film of a Omega Lexus powered 4L V8 Turbo'd putting out 1000BHP - More fun than a Bugatti Vyron if you ask me
