I haven't turbo'd a Z, but I have installed a draw through setup on my 79 RX-7. Besides the basic kit I also had to tap my engine for an oil line, take off the oil pan and weld on a connection for the oil return, and I installed a oil pressure guage, new fuel pump and fuel pressure regulator. I welded a bung onto my downpipe and installed an o2 sensor with an A/F meter mounted in the dash.
You'll have to come up with a way to get the air/fuel mixture into the turbo first, then into the head. I'm not sure if anyone makes an intake manifold like that for the L24.
I had two problems with the draw through setup, the first was starting the thing. The air/fuel mixture has to run out of the carb, down to the turbo, around it (it won't be spinning at idle) and back into the motor. I notice it took a good 4 or 5 seconds cranking on the thing to get it to fire.
The other issue was the idea of having atomized fuel running through a hot turbo. I never had it ignite in there, but it was something that Corky Bell warned about in his book. The compressor side of the turbo will get hot, there's no doubt about it.
I believe there's a chance of it condensing in an intercooler if you are thinking about running one too.
Hope that helps...if I were you, I'd look at swapping in the turbo motor from the 280zxt. EFI and a blow through setup would be worth it in my opinion.
