I put together my kit for under $1200 and yes it is all the stuff you see on ebay that supposedly cracks but it doesn't because you hear that BS from other idiots that don't use them so they say it cracks. Take it from someone who actually has the stuff and uses it every single day, not from some bozo who will scare you away from using XS power products. I use XS everything. I have a 1995 GSR with

T3/T04e 57 trim .63 a/r turbine .50 a/r compressor
Stainless steel tig welded equal length turbo manifold
custom made 2.5" d.p w/ flex section
tial style 35mm wastegate
tuner toys oil line kit
SRE intercooler piping
greddy type-s style BOV
OBX fmu 8:1
uberdata basemap
255lph fuel pump
custom FMIC 25x9x2.5"
purosil turbo coupling w/ stainless clamps
Tig welded oil pan w/ return fitting

Currently im running 6 psi boost controlled via the wastegate. You don't need to drop $3000 on a kit, do what I did its the same thing minus the names.
