mindflux, i don't know much about the actual Trust TD-06 17C, but according to http://www.capa.com.au/prices_turbo.htm it's priced at $6000 for the kit. But the kit is for the CA18. So that makes me wonder whether or not it will bolt up to the standard RB manifold. Do you have R32 or 33?
And by the look of these photos ( http://www.240ztt.com/zfuture.html ), it will not fit the standard manifold. So do you want to make a custom one or is that out of your budget?
How much is he asking?
I'll have a bit more of a look for specs.
