a clubman is not a modified car it is a constructed car (ie: from scratch)
also has a full chassis
that link apears to have been moved but you should be able to find it easy enough
dont see why you would need to remove the vin # ,there is still only one of them

dont think airbags are actaully, think i heard something like that at some point in time....but then i could have just as easily not heard it

my mate didnt have to do that i think, because its so few cars they dont bother eg his has no airbags. arnt they standard these days ?

dont you then need it to comply to all the new car regs? crumple zones and what not?

if i cant get mine liced i might say its a fully home made car like my mates clubman ( just grind off the vin number)
i have done heaps of body mods

to get SR20DET engineered it has to be classed as a comercial vehicle, and your engineer needs to be confident in your abillities and in your car.by no means impossible.

that link dont work / does go anywhere helpfull

ive done mine, if i dont include doing things twice and stuff like that, for around $3000
thats
CA18de+t, r31 diff, fully adjustable front end, r33 skyline brakes front and rear
thats doing everything myself, apart from getting an axle cut down for the diff and the tailshaft shortened
but you dont really need as much as what ive got, i only did most of it coz it was cheap to do

a close friend just got his 680kg clubman liced with a sr20det ALL BY THE BOOK
maddat has his fully complied
then theres 4 more i know that are liced
im not a big reader dazza1200 but i allways find there a loop hole eg theres the old its a commercial vehicle loop hole
ps ill have a read tonight ( boring dpi stuff)

i would think they are either not legal or someone has done some dodgy paperwork
check out national code of practice below
you want ncop3 la engines
read it and tell me i'm wrong
