Hey B310gx. That's the exact sort of thing I'm after. I wasn't aware the weld-in injector bosses are available, but would be very handy. My plan is to use a VL throttle body, and injectors, as these are also cheap and plentiful. Thanks, you've been a lot of help.

1200rallycar, I'm planning on using a T28 bb turbo and I think that plenum might be a bit restrictive. I'm not sure I haven't seen one, what do you reckon?

If you want the best intake using that idea, I'd suggest using a dual Weber DCOE intake instead of a SU/GX intake and then make a plenum matching to where the carbs would go and then into a single throttle body and weld in the injector bungs. I don't think it would be very hard to do. I would do something like that if I had a better intake, mine's got some repaired cracks that wouldn't hold up to boost. One of these days I will get around to trying out that Nissan EFI setup. I'd love to compare that against the dual 40mm Delloro's, as well as a home made one like described above. All in due time.

Have a look at this site. It has heaps of good info. http://www.sdsefi.com/techinta.htm

That's an excellent system. There's a huge following for it here in Okinawa. I was going to run my 180 with it when I put my RX6 turbine kit on and will use it if I get tired of the A12 and drop an SR or CA into my truck.

Here's a couple of Okinawa cars with it:

I have just made a master for the cylinder head inlet flanges for the A15/15 head. I propose to have a few of them profile cut with a view to putting an EFI system on our car.
I will fabricate the manifold myself.
If you are interested I will get extras done at the same time.
Please let me know.

Stew, Where are you located? Do you have any idea of the cost of the flanges? Barry

Not sure how good my injection is, its still sitting in the shed waiting to go on, the throttle body looks small but thats not hard to change, i plan to twin turbo it later on so i hope it work good with turbo

someone said they dont flow as much as twin webers but cant remember who it was or if they really knew what they were talking about

good luck finding something

ill take some detailed pics with my new camera if you like

ummm...all I was really interested in was the size of the inlet behind the throttle body. Because, like you said, it wouldn't be hard to adapt a larger throttle body to it.

But, I think I'll end up just making one up myself. I've been wanting to buy a TIG for a while anyway.
