The rims are a brand called "Racing Dynamics" they're for BMW's.
Haven't got to dyno it cause I still gotta wire up the maf and finish the tune. Hopefully soon.

Re: My 5.3L 91 Z28 build thread (goin to be slow)
so im thinkin about goin turbo. ive done it before but never really got it tuned completely so never got to feel the full experience. plus ive never driven a turbo automatic car.
so im thinkin truck manifolds, probably a T70 turbo, intercooler,wastegate,low off valve and whatever little things i need. my exhaust guy has been waiting for me to say yes to turbo it so i know hes ready to do it just need to start gettin parts.
will probably look very close to my rx7's setup but probably a little cleaner.
