This is how it was used on my brothers car. I make manifolds, the uk one isn't restrictive in my opinion, not the best flow velocity wise but I've seen lots worse! There was some really good threads on tggt on ecus and on engine differences but I can't find them now.
fair point, ok, its a low milage JDM engine, injectors, inlet mani, an ecu which is plug and play in a uk ep90 (proven and tested on my brothers uk ep90) and uk exhaust manifold. Heres a picture of the ecu
yeah £25 each. No back box im afraid I do have an over axel pipe but no box on it as it fell off lol but it may be of use to you? Ie buy a box off ebay and get it welded on somewhere?
