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 2 straight, 2 45 degree bends, and 2 90 degree bends.
misc piping hoses and t-bolt clamps

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