Put on a PLOG, HAI, Downpipe, and an HV3. Then get a tune. Should add some noticable pep and MPGs.

Run that setup while saving for a z7 kit and a fully built TEP 4t65e.

When sufficient funds are obtained for not only parts and labor but also some for when/if things go wrong, then install the turbo and trans in one shop trip.

Then you would have a nice flowing and powerful set up.
