this is not a bolt on kit. it will require exhaust and intercooler piping fabrication. i bought it for my 97 cavalier but sold it the week i bought the kit (figures). i was going to install it on my 98 s10 but i decided the truck wasnt worth the money. this kit is new, not used.
it comes with the following:

t3/t4 hybrid .50 a/r non water cooled.
fmic (small dent at bottom from shipping. didnt damage anything)
external wastegate
blow off valve
manual boost controller
2.5" aluminum intercooler piping with straight, 45 degree bends, 90 degree, and u bends.
misc piping hoses and t-bolt clamps

600.00 for everything. will split if the price is right.
