I had an sc14 on a fuel injected a15 in a datsun 1200,
I hated it ::)
it was got on pick up, but ran out of puff after 4500 rpm,
and it was soo noisy on the freeway!
I dont own the car any more but i have been told by the new owner
the car has now been fitted with a t28 turbo  and it goes about 30% better and is better on fuel

Depends on what driving you do.  Motorkhanas and small tight hillclimbs/curcuits are perfect for them, turbos are shit for it.  Don't get me wrong, I love my turbo, but I hate lag with a passion.

can you program your ignition if so then give it more timing off boost to account for the low compression that will help fatten up the low end power

yeh, i am only on a street tune atm, be lucky to have 110rwkw, but its my turbo that lets me down in the lag dept.  Its a high flowed, Journal bearing item with a larger VG30 housing.  Its strong, but its slow.  Ill see how it goes when i get it tuned properly again and then go from there.  I would love a GT30RS or similar, but I didnt win lotto.. :D

you could go twin charge. supercharge for down low and turbo for higher rpm.
I have seen it done and the s/c had a bypass for when the turbo came on boost

Lancia did this on their rallying Deltas.  Some other makers have done it before as well.

Maybe run a twin entry ballbearing turbo
Boos lag is really a thing of the past nowadays with modern correctly sized turbos

SC14 supposedly bolts up to the lower mounts on a 280zx aircon bracket but needs some sort of mod to the top mounts.  Could be worth looking into.
My little brother had a VS commode with an SC14 that pulled hard up to 6k, so if you get the pulley dimensions right it should be fine on an L28.

Yeah turbo technology has improved shit loads since people realised V8s weren't the only way to make good power. I have long wanted to SC the RB25 and have heard of it being done.  I reckon with the Autronic it wouldn't be too hard, but I have spent enough money and am going to just concentrate on what I have. 
Sorry to hijack this a bit.

The SC14 bolting to the L28 sounds promising.
