To complete the install you need 3/4" hose to run from heat exchanger to the IC. Barb fittings, couplings, elbows and whatnot. Hose clamps, maybe some zip ties to keep everything tidy miscellaneous hardware (heat exchanger) and a fuel rail solution weather its modifying your rail, purchasing a modified rail or fuel log setup or find some injector spacers. I believe that is all.
