AIT turbo kit on TD42

[YNOT]

But Tony if he has the setup in the first pic he'd be nuts to take it out surely?? If you do mate i got first dibs!!!

He'd be near on better off looking to fit a second battery in the back if he has to? I have seen a guy turn the battery around on the right side and fit 2 next to each other front to back there, tight squeeze but all good.

Yes and no. You'd be hard pressed to find a better flowing high capacity air filter assembly than the big Donaldsons, but the ZD30 airboxes flow more than enough for most regular turbo set ups, the Patroldocta air box is somewhere in the middle of those two.
Andrew has to weigh up his options, including your suggestion of fitting 2 batteries on the R/H inner gaurd, and decide which option will best suit his needs. To fit 2 batteries on the R/H inner gaurd I would suggest reinforcing the gaurd, they have been known to crack under the weight of just one battery.
