If you get all the other parts but keep all your stock internals and compression, you could probably run 7-9 psi maybe? (someone correct me if I'm wrong, I'm not exactly sure)

Sounds about right. The ECU can stay and has to stay if you have an atx but if you swap out the base/SL ecu for the tt ecu then I've heard that there are considerable gains in hp.
Also very true, there is no real 'turbo kit' in production except for the vr-4 which is just a kit to upgrade the turbos already on there.
Look on 3si.org and see if you can't find some used parts for the conversion but it's going to be a bitch to get it all done, I just got done selling all my parts.
