I doubt the 20V throttle bodies are a DCOE pattern.

It could be done if you fabricated an adapter between the throttle bodies and the 2T-G manifold. It certainly won't just bolt up. If you want ITB's without the hassle of fabricating stuff, you can get DCOE pattern throttle bodies which will bolt right up to any DCOE manifold (which is what the 2T-G has). These are available from quite a few manufacturers, including some big names like Holley.

Motec, Speed Technolgy and Injection Perfection all sell DCOE style throttle bodies which will bolt straight up to your twin Solex manifold.

A full "kit" of twin DCOE throttle bodies and all the linkages/fuel rail will set you back around 1K minimum. Then you need to buy some injectors.
What I would do (if you have the 20V throttle bodies already) is get the bottom half of a 2TGEU manifold and fuel rail. Take it to a machine shop and get them to make a plate that matches the 20V throttle body spacings and stud patterns. Cut and shut this to the manifold. Hopefully the runners will not need too much modification to match everything up. That way you have the injector holes in the right spot, you can use a Toyota fuel rail and ND injectors.

Not sure.....if they do then ignore my comment about the injector holes.
Maybe I am getting confused with the 3SGEs...their injectors mount in the head.

The 20v throttle bodies don't have injector mounts. Having built up adapters for them in the past, I'd suggest getting some speed technology ones. Much easier.

Just use the existing Solex's as throttle bodies, and add injector ports into the inlet manifold.

It's mechanically pretty much all done, it's just wiring & plumbing to go mainly.
I'll do an update of it on my home page in a week or so.
