In all honesty for suck through it won't matter, boost will be the limiting factor as with no inter cooling or cooling the air a j pipe would do. Just bend some exhaust pipe and weld a flange for the turbo onto it.

i had an A14 turbo setup years ago, used a T2 turbo off an ET pulsar, stock engine with custom turbo manifold, blow through, modified 32/36 weber with a custom box/plenum hanging off it. oil return pipe into the sump, forget where the oil feed come from, went pretty hard, was heeps of fun and more of a novelty than anything.
Would love to build another one, make sure that if you run a brake booster you run a valve in the vacuum line and i think the dizzy may have also been locked or modifed, cant remember. Also had an electric fuel pump and fuel regulator.

have a read of this, dude talks about weber setup on an A14 with some good information.

That is blow through mind you, means you can run a blow off valve and intercooler, i dont really like draw through setups. Its ugly, cheap and i dont like the idea of fuel sitting in a hot turbo/plenum etc.

Also check this setup

Then all you need is an A series turbo manifold, Turbo, cross over pipe and exhaust and you will have a pretty tidy setup which will make decent power.

Awesome stuff
I have seen much debate on draw through vs blow through
I think for a simple budget build draw through will be fine. A lot of people in this forum have had great success with draw through

draw through is technically superior to blow through.
blow through just add a bunch of problems that need to be overcome with more parts, added comlexity, reduced reliability, more weight and extra cost.

when a draw through system can ice up the outside of the inlet pipe post turbo, you don't really need an intercooler for a street car using short bursts of boost. But competition engines like unlimited class ski boats that run at or near WOT for hours on end used intercoolers on draw through twin turbo V8s for decades, and stuck with it for a long time after EFI became cost effective.

BOV's simply aren't needed when the throttle plate isn't being shut on pressurised air! A BOV would never open on a draw thru setup if you did fit one. The 'need' for that is one of the many disadvantages of a blow through setup.

Just done a quick look in my garage and found a reco"d Garrett M24 Ar48. Would this be too big for a mildly worked A14 ??

Is that the front housing Nick might be ok whats the exhaust housing? .48 or .63?, plenty of t25 used on draw through without issues providing not too much boost and high compression. Especially with an A15. Draw through simple & effective for 100hp atw.

Clyons8 is doing log style manis for a great price, they work better in low / midrange to 5000 rpm after that equal length come on their own but only 15% improvement. Log styles are well proven for 100-280hp 4 cyls with excellent area under the graph if well tuned in DT carb or BT efi.
