Matt,

I used a kit and a little imagination.  I'm not much of a motorhead or wrencher but I found that everything was well within my capabilities.  If stoich is considered a f/a ratio of 12.5 and 14.5,  I would say that under acceleration I run around little less than 12 and cruise a little below 14.  Obviously the A/F is changing constantly but I would say those numbers are fairly representative.  Clarify, hold or surpass a very well tuned VR4. Once the headers and exhaust system is installed, necessary in preparing for water/meth injection,  I'll have it dyno tested.  I'm shooting for 290 at the wheels or about 365 at the flywheel which should keep the GT well behaved and streetable.

Did you end up using a kit, or did you put it together yourself?  I
hope it is stoich only while cruising - while under boost you want it
richer than that if you want to get longevity out of the pistons.

I'm guessing you meant "stock VR4" there...  ;-)

Congrats on a successful project!
