I am running a 1991 240sx. It is sporting a K&N cone filter, flowmaster exhaust system, nology hotwires and stillen metal matrix brake pads.

I'm looking at preparing for a turbo upgrade through JWT or NSport.

Let me know what you think.

No problems on the turbo.  The '91's can handle, i think, 9psi on stock internals.  That should put you up to about 250 hp.  If you rebuilt the engine with forged pistons and lower compression ratios, you can go way up on the boost.  I dont know much about JWT turbo kits, except that he doesn't have a price on the website.  I do know that NSport and FMax are in competition with each other.  It is a prefrence between the two, as both are claiming 240hp (on a s-14).  There is a couple hundred dollar price difference between them.  
I don't see why you would want NOS, unless you have a big-ass turbo and want the JWT system to fill in for the turbo lag.
