You kinda just gotta look around. Where at are you locatated? You might be lucky enough to find a member on here closeby so you can go and buy/pick it up from them (thats what I did, thanks Russ
).
Other than that, I think therewill be a couple kits available from people on here. Might wanna look on ebay, type in banks turbo, and go from there (to ATS turbo, then hypermax turbo, thats what I always did when I was on the market for one).
Or go onto your local craigslist and look on there for one. Or go to some wrecking yards and look around.
