I picked up a complete dual plug Tec 1 setup for a very good price, so I will be using that. I was think MS, but then this system came up, and it was very close to the MS cost once you added the sensors, and ignition components.
I will replace the washers with spacers, the standoffs for the fuel rail that were on the TB are long enough and the right sizing.
For injectors I am using a set of Acura/Honda injectors, they are the correct size to fit the bungs on the TB's as long as you use the Suzuki o-rings. And I picked up a complete set on e-bay for $130.00, they are available in just about any size you want as the Honda crowd is forever replacing, up-sizing as they turbo/NOS their motors. Quite often almost brand new from a blown motor
I am going to try the throttle position sensor that is built into one of the throttle bodys, it is a three wire, and seems to be within the same range of resistance as the Bosch one I got with the TEC unit.
Just filled in the holes left when I removed the upper throttle plates with JB weld. Once it is dried I will sand and polish it down. Then onto fabbing some linkage arms.
Oh, and one of the manifolds I bought was from a sportamatic so it was drilled and tapped for vacuum fittings on 2 of the runners, I did the same to the other as the standoffs are there, just not dilled through, just need to drill at an angle into the manifold.. That will be my vacuum source for the MAP sensor.
The thottle bodys have vacuum ports as well, but I am going to use those for Idle Air as the are located directly under the throttle plates.
