I am building a new engine and wanted EFI and ITBs. I had some MFI stacks around and thought I would just adapt these. So I made some EFI adapters that screw into the heads in place of the MFI injectors.
I like the Siemens Deka injectors that were originally used on BMW applications. They have 21mm tips and almost protrude into the intake tract. Very much like the MFI injector.
I made some fuel rails but did not like them. I decided to make a flex line system similar to the RSRs. I just got my parts back from the plating company. They came out great.
Now I just have to finish building the new motor...
Oh, these will likely be offered in the catalog very soon by our sponsor.
