can this be done..?? or do you have to have the s1 runners machined to take electronic injectors...??

 

doesn't fit.

 

The holes for the injectors on the plate beteween inlet and cylinder head must be modified. I've seen some here, I'll do that to my RS1600i manifold in a few weeks and a friend of mine did this many years ago to his RSi manifold to make the WeberMarelli out of the Sierra4x4Cos fit onto his CVH
