yeah sounds like you need to read some more before you start working on it - its the only real way to learn ... the 190cc's on the y7 are FTL ...
also agree'd you need to worry about CFM as well as the psi ...
also try registering at turbod16.com - you will learn alot there as well.
I have a y7 - I am buying new gaskets this week and starting my turbo install the end of july when I have time off - here is what im running to give you an idea of a parts list ... the turbo and manifold Im using can obviously be swapped out for parts of your choice: also the Intake manifold on th y7 sucks - if you can find one get a y8 intake manifold.
d16y8 intake mani
arp head studs
Log manifold w/ bmcrace adapter plate
14b Turbo
precision 310cc injectors
godspeed intercooler
custom necessary piping and 2.5inch down pipe
turboxs bov
golden eagle vacuum block
chipped p06 w/crome and OBD1 jumper harness
thats a basic list of my parts so you can compare if you want
