Here's the engine as it is now, i just made a new stand off injection set up for it, the old fuel rail and trumpets couldn't handle the vibration at big revs and used to break, i'll upload a few pics of the manufacturing process
I was at a mates place and saw this old fuel rail from a corolla and thought the injector spacing looked similar to my trumpet spacing, took it home and sure enough it was prety close, i got out the sketch pas and drew up a plate to allow me to hold the injectors into the rail in my "stand off" placing and went to work machining up the other associated parts
Here's the collars that will hold the injectors in, precision drilled to fit the end of the injector tightly, and i chose to cut a thread in the collar instead of using nuts, so there isn't any chance of anything falling in the inlet, then i helecoiled them for extra thread strength
I machined the uprights to be counter sunk at both ends, at the fuel rail end the upright actually hold the whole deal together. Counter sinking gives it a lot more strength and a huge amount of regidity
Then i Machined the injector stays, Machined to the perfect length so the injector isn't rediculously tight, but won't be moving anywhere
Here's how the injector holding arrangement looks so far
Here's a better idea of how it is all held together in the rail
And here is the semi finished product
And here's how it mounts
