On thinking of doing the EFI part of this!
But go for an SC12 in stedas it is easier to get legal where i live. What about fuel? Is this done nu the stock fuel pump of electric one? + Ill prop. Go 2/4 injectors, would same setup work there?

Stock fuel pump is 2.6 psi. All EFI requires a high pressure pump, at least 14 psi, but usually more like 40 psi.
I'd recommend a fuel pump off a Datsun 280ZX or a generic EFI pump, like the famous Walbro: $127 and up

The vapourization issue? I'll just see what its like with the turbo. I do have some ideas to fix it if its still there.
The actuator mount is this mornings project. On Ziggy's, I made a mount that bolted to the underside of the inlet manifold, and lengthened the rod with all thread and a tube nut. I'll post more pics as I progress.

Turbo to TB plumbing done. Waste gate actuator next.
It took longer than I hoped, I had to make a 2 bolt flange out of steel to weld to the tube. Attach file: A12 single injector engine,turbo plumbing.jpg (196.71 KB)

Anyone want to guess the KW?
It made 29Kw with the standard engine/carb and ign last week on the test stand. It now has the single injector, turbo(single turbo off the R32 TT skyline) wasted spark ign, E85 fuel and 15psi actuator. No intercooler. It cranked 150Psi in each cyl during a compression test but has never been pulled apart in 35+years. I just hope the old head gasket holds up! Anyone for a guess???
