You must have the Meth injection to run the Roe. I guess you could engineer and have someone build an intercooler to work, but the Roe is engineered and designed to have meth injection...it is only a few hundred dollars and is not complex. The methanol is just windshield washer fluid...methanol is what keeps it from freezing in the winter. It goes in your windshield washer reservoir, hell what you have in there now will probably work. It is a pump, that is activated by the VEC III and the methanol is injected in the throttle body via a small hose to a nossel (sp?). The only other piece is the pump, it mounts on the fender wall next to the fuse box. Oh, there is also a LED that is put in the cab to let you know when the meth is being injected, and a test button that goes on the fender to the right of the battery.
You mush have it. If not, under boost.....
BOOM!
