if you wanna fully build your engine add rods and sleeves to that list. i just listed a t3 turbo manifold on ebay for all b-series engines. search by seller for cavguy23. my reserve is 120 if you are interested. it is better to have a cast manifold bc the tubular ones tend to crack from daily driving. greddy, hks, turbonetics are some excellent brand names to look for when buying anything turbo.
