308qv efi manifold conversion

There's a couple options on this.
The biggest hurdle is the throttle body sitting right in the way of the fuel rail.

The next one is injectors, majority of injectors now are the new molded plastic ones. The old metal body are getting harder to source.

When I started with the EFI conversions I started with the metal body ones, made an adapter and had custom injectors machined with threading.... Then it got harder to source injectors.
With the advent of printing, I now print custom parts that retain the modern injector in the port with no machining or welding needed.

That still leaves the fuel rail issues... Depending on comfort level and budget, there's everything from custom hand bent lines that look OEM to the new manifold and throttle body we've been using on builds to just running a sectioned 'D' rail.

Kinda comes down to what you're looking for.
