i just droped a b20b w/a hydro b16 tranny into my eg hatch. it came wit the stock b20 manifold. but i put an 94 up ls manifold. but i dont know wat throttle body 2 use. i have my 2nd gen b16 throttle body on it. but the rpms starts to go up in down.. everything else is fine. wat TB should i get.. looking for a stock one that is capable for my engine. thanks..
