you could megasquirt it, (MS2V3), ($250 starting)
now with custom ecu you are free to set it all, where you want.
the injectors, i do not have the spec on the stock ones.
if you cant find it , you can send one to witchhunter.com for cleaning $18 and the sheet that comes back is full spec.
now pump that (no pun) into the Required fuel calc at MSquirt web site and behold the answer.
RQ is the maximum fuel used under full boost, in your case.
really, the cost is a very expensive turbo, and the MS is cheap.
so all the money goes for dyno time.
no matter if you do it the correct and safe way with a real ecu or with a piggy back , you still have to tune it for no boost , and the full boost.
remember the turbo wrecks the no boost volumetric efficiency so must be re-tuned for that ,too.
keeping the stock ecu is madness, as no man alive ,can tell you when or what stock ECU will do next ,under boost. no one.
so it all boils down to tuning costs.
most likely 2 times the hardware.
but do not let me dissuade you, there are many junk yard turbo projects that are successful, google that for fun !
but in that case , its all throw away , any way.
cheers.
happy boosting.
if at anytime the plan fails under boost and it goes lean, say goodbye to engine.
you also need that fancy knock detector as a fail safe independent device so if something goes wrong , it may save the farm.
all this and more , in jeff hartmans new book, "tuning for speed or economy".
sold at all book stores.
best book i have ever read, on engines and i have a large collection.
cheers.
