yeah that looks very neat, so basicly if i but a decent efi set up get someone to fab up some manifolds all should be sweet?

Well there's a fair bit to it than just that but sure that's the general idea.

If you are going to go through the effort of building a manifold you might want to go with the oval port head as these are a better performer than the round port. Probably one of the best upgrades you could go with.

So if you build the manifold to suit the oval port head you'll save yourself having to do that modification later.

cheers mate good info just wish there were off the shelf n avalibilty in parts lol..

Here are some cheap setups, it's up to you to make sure they are the right bore size etc. I'd think anywhere between 30 and 36 would suit a mild A12, for a worked A12 I reckon 36-40mm and for bigger capacity worked A14 or A15 then 40-46mm should do the trick (you should do your own research really maybe send lagwagon a text about his setup).

unless im sure they will fit a a12 motor i would not be confident in this. but that is exatcly what imn after though

There are many off-the-shelf parts for A12 EFI. Most use a DCOE carburetor manifold, but don't use the carburetor itself instead use a pair of dual-ITB (individual throttle bodies).

See EFI for photos and parts. A decent EFI computer starts at 200 kit. You could also use a stock Nissan computer from the wreckers.
