Airboxes and ECUs are free in STU, so the only thing you need to request are injectors (normally "free" but limited by the spec line) and the JCW exhaust ports (you can port in STU but you'd have to add 1% to the weight.

Again, I don't recall if the stock injectors was a conscious decision. Make a request with this data to allow "open" injectors and at a minimum we can dual-line-item the engine if the STAC/CRB thinks it's too much for the existing class weight. - GA
