Can I easily add the 'rocket boosters' to any car?

I love driving the Evo rally car because I can just hit the 'T' key, and now all other vehicles are boring and slow.

Is it difficult to add these mod to other vehicles?

doesnt work anymore. dunno why...I tried using the code he provided, making them myself, and copying an old version that is working and in 0.8.3 they no longer work....I read somewhere they were broken for now? Or was that the NED, that breaks the thrusters? Anyone?

 

hmm, well I dont have NED, and when I try to add thrusters to the covet, nothing happens with G or H......wondering why, as it used to be copy-paste code to the end of the covet body jbeam and bam, you got thrusters...

 

herre is my code....the nodes defined in the thrusters are correct to the beams they should be attached to. this appears to be correct...wonder whats up? this is the same code exactly that works on my old-school install (I use the old school versions sometimes lol)
